- The Rabbis instituted to say Pesukei Dezimrah starting with the blessing Baruch Sh’amar and ending with the blessing Yishtabach. 
- In Nusach Sefard, Hodu, Hod V'Hadar, V'hu Rachum, Hoshiah, Mizmor Shir, Hashem Melech, Hoshieinu, and Lamnatzeach come before Baruch Sh'amar. Hodu is put first since it is related to Korbanot. Part of Hodu was sung in the Mishkan and the Tamid service every day until the inauguration of the Beit Hamikdash from 43 years before. 
- One shouldn’t add to the Mizmorim or repeat them unless he wants to repeat something for which he didn’t have Kavanah the first time. 
- One should stand for Baruch Sh’amar and Vayevarech David until and including Atta Hu Hashem Elokim and Ashkenazim also stand for Yishtabach. 
- Someone sick or old can say it seated. 
The time of Pesukei Dezimrah
- The time to say Pesukei Dezimrah is from Olot Hashachar (72 before sunrise) until the 4th hour in Sha’ot Zmaniot. 
- If one missed the time unintentionally or unwillingly he can say it after 4 hours until Chatzot (when one can’t say Birchot Shema but can say Shemona Esrah). However it one missed the time intentionally he can only say Baruch She’amar and Yishtabach without Hashem’s name in the Bracha (and Shemona Esrah should be said with a stipulation that it should be voluntary if it’s unnecessary). 
- If it’s after Chatzot, or one said Shemona Esrah before he said Pesukei Dezimrah, he should only say Baruch She’amar and Yishtabach without Hashem’s name in the Bracha. 
Women saying Pesukei Dezimrah
- The practice of Sephardic women is that since there’s no obligation, if women want to say it, they can only say it without Hashem’s name in the Bracha. The practice of Ashkenazi women is that they say the Bracha with Hashem’s name. 
Amen after Baruch Sh’amar and Yishtabach
- If one finished Baruch Sh’amar before the Shaliach Tzibbur one can answer amen after the Shaliach Tzibbur finishes Baruch Sh’amar. 
- If one finished Baruch Sh’amar with the Shaliach Tzibbur one can not answer after the Shaliach Tzibbur finishes Baruch Sh’amar because it looks like one is answering amen to one’s own bracha. 
- The Sephardic custom is to say amen after one’s own bracha when it concludes a significant section such as saying amen after Yishtabach. Ashkenazim have the minhag not to say amen after one’s own bracha as after Yishtabach, but if one finishes Yishtabach with the Shaliach Tzibbur he can answer amen. 
Interruptions in Baruch Sh’amar and Yishtabach
- When one is saying the beginning of Baruch Sh’amar or Yishtabach before the words Baruch Atta Hashem, one can answer Kaddish, Kedusha, and Barchu. 
- When one is saying the Bracha of Baruch Sh’amar or Yishtabach after Baruch Atta Hashem, one can’t answer amen to a bracha. 
- When one is saying the Bracha of Baruch Sh’amar or Yishtabach after Baruch Atta Hashem, one can answer Kedusha, Barchu, and the first five amen’s of a Sephardic Kaddish and three amen’s of an Ashkenazic Kaddish. One shouldn’t answer Barich Hu. When one answers Amen Yehe Shem Raba one should only answer up to Ulmiya Yitbarach and not until De’amiran Be’alma. 
Interruptions in middle of Pesukei Dezimrah
- After the fact, if one did interrupt during Pesukei Dezimrah with talking unrelated to prayer, according to Sephardim, one doesn’t repeat the bracha (Baruch Sh’amar) again. [According to Ashkenazim, one has what to rely on to repeat Baruch Sh’amar.] 
- When one is saying Pesukei Dezimrah, even right after Baruch Sh’amar before the zemirot, and even during Baruch Sh’amar before the bracha part, one can answer amen after a Brachot he hears from his friend. 
- When one is in between the zemirot, one can interrupt just one would by in between brachot of Brachot Shema, meaning one can answer anyone’s greeting or greet a person who is due respect. When one is middle of one of the zemirot, one can greet someone who one has to fear such as one’s parents or Rabbi and one can answer the greeting of one who is due respect. Yet some hold, nowadays, when no one is offended by not being greeted one shouldn’t interrupt. 
- If one needs to tell others the page number it’s preferable one use a page number cards, but if that’s not available and it’s a great need one can speak. 
- Sephardim should answer only the first five amen’s of a sephardic Kaddish and Ashkenazim the first three amen’s of an Ashkenazic Kaddish. Barich Hu shouldn’t be answered. Amen Yehe Sheme Raba can be answered up to De’amiran Be’alma. 
- One can’t answer Baruch Hu U’Baruch Shemo. 
- One can answer the following in Kedusha: “Kadosh Kadosh…”, “Baruch Kavod…”, and “Yimloch Hashem…”, but not the entire kedusha. 
- One can’t answer the Kedusha of Brachat Yotzer or Uva Letzion. 
- One can’t interrupt for the Vayavor and the 13 midot, [but those who have the Minhag to say it, have what to rely on]. 
- One should answer only the first three words of Modim Derabanan, “Modim Anachnu Lach” and the rest one should just recite it mentally. However, those who have the minhag to answer the entire paragraph may answer it. 
- Sephardim shouldn’t say the first pasuk of Shema with the tzibbur, rather one should cover one’s eyes and continue to read Pesukei Dezimrah. Ashkenazim should answer the first pasuk of shema. 
- One must stand up for a Torah scholar or elderly person (70 years old). 
- One who hears thunder or sees a rainbow, can interrupt for these brachot because they are a passing mitzvah. 
- One can put on talit and tefilin between mizmors and if one’s up to Yishtabach he should first say yishtabach and then put on talit and tefilin. 
- If the Zman Kriyat Shema (even if it’s just the Magan Avraham’s time) is about to end within minutes and it’s not possible to skip zemirot, finish Pesukei Dezimrah, brachot shema and shema, one may interrupt Pesukei Dezimrah to say all 3 paragraphs of shema. 
- One who went to the bathroom, should say Asher Yatzar, put on talit without bracha and put on tefilin with bracha between mizmorim and if he was in between Pesukei Dezimrah and yishtabach he should wait until after Yishtabach. 
- A mourner within 12 months of the death of one of his parents, can interrupt with “Kaddish Al Israel” but should be careful to only to interrupt when he’s between mizmorim. Those who want to say the other kaddishim that one has the minhag to say as a mourner has what to rely on. One has what to rely on to say “Kaddish Yatom” between “perakim” of brachot kiryat shema. 
- One can’t answer the Vezot Hatorah of Hagbah or Barich Sheme when the Aron is opened. 
- One should not interrupt to listen to Kriyat HaTorah if he can hear it later from another minyan. If not, he should listen between the mizmorim. 
- If one was called for an aliyah by name one should make the brachot and read along with the bal koreh as usual. If one wasn’t called by name he should refuse the aliyah by signaling. If one’s the only Cohen or levi there he can take the aliyah even if not called by name. One should finish the pasuk he’s in but not the paragraph unless one is close to the end. One shouldn’t ask the shaliach Tzibbur to say a mesheberach. 
- If one gets the maftir Aliyah, he should say the Haftorah with Brachot. 
- If there is no one else who know how to read the Torah with the tune and correct pronunciation, he may interrupt (even in Shema), but shouldn’t say misheberach’s. One can interrupt to correct the Torah reading if the mistake changes the meaning. 
- The tzibbur shouldn’t add piutim in Pesukei Dezimrah or Brachot Kriyat Shema, but should be said after the Kaddish Titkabel after Shema Esreh. Ashkenazim allow the tzibbur to add classical piutim even in Brachot Kriyat Shema, but shouldn’t add new piutim. 
- Even though one isn’t obligated to interrupt even for the Dvarim Shebekedusha that are permitted to answer it’s proper to interrupt for them; initially one should place oneself in a place that he can’t hear the Dvarim Shebekedusha so won’t have to answer. 
- One shouldn’t smell Besamim and make a bracha since it can wait until after davening. 
Interruptions between Yishtabach and Brachot Yotzer
- One can answer any dvar sh’bekeusha, including Baruch Hu UBaruch Shemo. 
- One can answer the kedusha with the entire passage of “nakdishach” or “nekadesh” 
- One can answer the entire Modim Derabanan 
- One can answer the first pasuk of Shema with the Tzibbur 
- One can answer Vezot Hatorah of Hagbah and Barich Sheme when the Aron is opened. 
- In Hodu, one should pause between the words “Ki Kol Elohe HaAmim Elilim” and “VeHashem Shamayim Assa” 
- Baruch Seh'amar should be sung. 
- Baruch SheAmar should be said standing. 
- There is a practice to hold the two front tzitzit during Baruch She’amar and kiss them at the end. 
- One who forgot Baruch She’amar can say it when he remembers even in middle of Az Yashir, but if he finishes Az Yashir he isn’t allowed to say Baruch She’amar or Yishtabach. Ashkenazim have what to rely on if after the fact they forgot Baruch She’amar that they can still say Yishtabach. 
- One should answer Amen while saying Baruch SheAmar before reaching the Bracha part of it. During the Bracha half one could answer Amen to any Bracha except for hearing someone finish Baruch SheAmar, however, during the conclusion, Baruch Atta Hashem Melech MeHulal BaTishbachot one shouldn’t answer Aman at all. The same is true of Yishtabach. 
- If one finished Baruch SheAmar together with the Shaliach Tzibbur one shouldn’t say Amen because it looks like one is saying Amen to one’s own Bracha, however, if one finishes Yishtabach with the Shaliach Tzibbur one may answer Amen. 
- Ashkenazim stand during mizmor letodah, but Sephardim don’t stand for mizmor letodah. 
- On Shabbat and Yom tov we replace mizmor letodah with mizmor shir leyom hashabbat and Hashem malach. Many have the minhag to also say the first pasuk even on Yom tov. 
- On Rosh Hashanah the majority minhag is not to say it, but some have the minhag to say it. Ashkenazim have minhag not to say it on Erev Yom Kippur, but Sephardim do. 
- Ashkenazim don’t say it on Erev or Chol Hamoed Pesach, whereas Sephardim do. 
- It’s to be said on Erev Tisha BaAv or Tisha BaAv. 
- One needs Kavanah that Hashem provides for all in “Pote’ach Et Yadecha”. If one didn’t have kavanah one should say the pasuk again. If one finished the mizmor one should repeat from Pote’ach until the end, and if one only remembers later, he should say Pote’ach between mizmorim. If one finished all the mizmorim one should have Kavanah in Ashrei after Tachanun or in Ashrei of Mincha. 
- Sephardim have the custom to open their hands during Pote’ach. 
- Ashrei is composed of two pesukim “Ashrei Yoshvei” and “Ashrei HaAm” before “Tehilat ledavid” and concludes with “VaAnachnu” 
- The pasuk of “Kol Hanishma tihalelya” and “Hashem Yimloch leolom va’ed” are repeated. The Targum of Yimloch is also read, followed by “Ki Ba Sus”. 
- Sephardim have the custom to give three coins to tzedaka during “atta moshel bekol” in Vayevarech David, two coins first and then the third coin. 
- Az Yashir is said even on Tisha BaAv. 
- In the pasuk “Mi Chamocha BaElim Hashem Mi Kamocha Nedar Bakodesh” the first kamocha has a soft kaf and the second one has a dagesh. Similarly, “Yidamu KaAven” has a kaf with a dagesh and “Am Zu Ga’alta” has a gimmel with a dagesh. 
- One should pause between the words “Tzalelu KaOferet Bemayim” and “Adirim”, however some say not to pause. 
- S”A 51:1. Rambam (tefilah 7:12) bases it on Shabbat 118b that one should say tehilim of Hashem’s praise daily. Rif and Rosh Brachot 5, learn it from Brachot 32a that a person should prepare praise before his requests. Tosfot Brachot 46a, Pesachim 104b state that since there’s a Bracha it must be an establishment of the Rabbis and not just a Minhag. The Pri Chadash 51 writes that it’s an establishment of the Geonim against the Birkei Yosef 51:1 who quotes Tur who quotes Sefer Hayecholet that Yishmael ben Elisha Cohen Gadol wrote Baruch She’amar and the mentioning of it in the Yerushalmi and Zohar.
- Beis Yosef, Orach Chaim 50
- Sh”t Otzrot Yosef 4:1 proves it from Siddur Bet Ovad (Hilchot Pesukei Dezimrah 66b) who says adding unneeded verses or repeating unnecessarily would be an interruption based on Rama 51:9. Similarly, Sefer HaEshkol says that since parts of Vayevarech David and Az Yashir aren’t part of David’s works they should be said after davening because of an interruption. However Yaavetz in Mor Ukesiah says one can add praises from tehilim as he likes and so the Chaye Adam 20:1 uses this to challenge S”A 65:2. Yet, since S”A is strict not to say the pasuk of Shema during Pesukei Dezimrah, S”A must hold that verses not established in Pesukei Dezimrah can’t be added, so holds Chida in Moreh Etzba 3(74), Petach Dvir 65:3. Yeshuot Yacov 51:1 says it may be an interruption to repeat the verse “Pote’ach et Yadecha” without Kavanah. Kaf Hachaim 51:33 one shouldn’t repeat “Pote’ach et Yadecha” in Pesukei Dezimrah. See further Sh”t Yabia Omer 6:5
- Concerning Baruch Sh’amar, Darkei Moshe 51:1, Rama 51:7, Bach 53 argue that one should stand during Baruch sh’amar. Taz 51:1, Eliyah Raba 51:1, Solet Belula 51:1, Shalmei Tzibbur pg 66(4), Mishna Brurah 51:1, Kaf Hachaim 51:1. Magan Avraham 51:1 says one must stand even one praying privately. Concerning Vayivarech David, Darkei Moshe 51:8 records the minhag to stand not like the Maharil, Arizal (Shaar Kavanot Tefilat Shachar 18c), Pri etz chaim (shaar zemirot 6), Magan Avraham 51:9, Eliyah Raba 51:9, Yad Aharon (hagot tur), Shalmei tzibbur 69d, Kesher Gudal 7:43, Siddur Bet Ovad 1, Mishna Brurah 51:19, Kaf Hachaim 51:43.
- Rama 51:7 writes that Ashkenazim have the minhag to stand during Yishtabach. Bet Yosef 53 quotes Hagahot Maymone and Kol bo in name of Rav Amram Goan that such is the practice. Sephardim don’t have this minhag as noted by the Bach 53, Shaarei Knesset Gedolah 53, Chesed LeAlafim 53:1, Ikrei Hadaat O”C 4:15, Yafeh Lev 53:1, and Kaf Hachaim 53:42.
- Mishpatei Tzedek 70 and Halichot Olam Vayigash 1 pg 75 write that an old or sick person may stay seated. Additionally, Biur HaGra 51:12 says standing altogether is a stringency.
- Elyah Raba 664:3 in name of Maharil, Mekor Chaim 18:3, Torat Chaim Sofer 51:1, Yechva Daat 2:8. The Yosef Ometz Uzfa is strict that it shouldn’t be done until closer to sunrise. However, Teshuva MeAhava 2 pg 6(3) and Meharsham BeDaat Torah 664, in name of Rashi, say that it can be said before Olot Hashachar.
- Mishna Brurah 89:6, and Yalkut Yosef (Tefilah 1 pg 140, Sherit Yosef 2 pg 256) say that by Shemona Esrah after 4 hours one can still pray only if one unintentionally missed the time as stated in S”A 89:1, however, whether one can say Shemoneh Esrei if one intentionally missed the time is a dispute of the Achronim and so one can pray with a stipulation. Halacha Brurah 51:6 writes, however, for Pesukei Dezimrah, since it’s a dispute and no stipulation is valid, we don’t say the Bracha as it’s a Safek Bracha.
- S”A 52:1, Aruch (Erech Tefilah), Machsor Vitri 23, Or Zaruha 1:100, Smak 12:77, Hagahot Maimon Tefilah 7:50, Rashba 1:589 in name of Ramban, Shibolei HaLeket 7, against the Talmedei Rabbenu Yonah Brachot 23a who say you can still say it after Shemoneh Esrei. Halacha Brurah 51:6 extends this also to where the Chatzot passed.
- Halacha Brurah 51:7 from his teshuva Sh”t Otzrot Yosef 4:3. S”A 589:6 says women can’t make brachot that are on time bound positive mitzvot and Rama says women can make these brachot. Whether women are obligated in Pesukei Dezimrah is a dispute in the Achronim. The dispute is based on the dispute in the rishonim where women are exempt from time bound mitzvoth that are derabanan. (Tosfot Brachot 20b holds they are exempt and Orchot Chaim (Hilchot Tzitzit 31) in name of Rabbenu Tam holds they are obligated.) Since pesukei dezimrah is a time bound derabanan mitzvah seemingly it’d be dependant on the dispute of the rishonim. In Siman 47, the taz and magan avraham imply from Bet Yosef that women are patur from Pesukei Dezimrah; however the Maharil haChadashot 45:2 pg 53, holds women are chayav and when Bet Yosef quotes the Maharil he leaves out that women are chayav. Mishna Brurah 70:1 implies from Rabbi Akiva Eiger that women are obligated. Or Letzion 2, 5:3 pg 44-5, holds they aren’t obligated but can still make the bracha since it’s praise of Hashem, but Sh”t Yabia Omer O”C 2:165, 8:8 argues that one shouldn’t make unnecessary brachot.
- S”A 51:2, Kitzur S"A of Rav Rephael Baruch Toledano, siman 11, laaws of tefila from baruch she'amar until yishtabach, seif 3, Tur 51:2 based on the Rosh in a Teshuva (Klal 4:19), Bet Yosef (51:2) compares this to a dispute of Rishonim of answering Amen after HaBocher B’Amo Israel Be’Ahava before Shema and then concludes by Pesukei Dezimrah we can be lenient since Amen is a praise of Hashem(fitting with the theme of Pesukei Dezimrah). Magan Avraham 51:3. Sh”t Yabia Omer O”C 6:4, 7:8(3), Yavetz in Mor Ukesia 65, Kiseh Eliyahu 51:3, Chida in Kesher Gadol 7:21,34, Pri Megadim A”A 51:3, Chaye Adam 2:3, Kesot HaShulchan in Badeh Shulchan 18:5 in name of Siddur Rav Zalman, Shalmei Tzibbur pg 67b, Sh”t Zechur L’Yitzchak Hareri 7:6, Rav Shlomo Kluger in Sefer HaChaim 59, Minchat Aharon 12(4). However the Tevuot Shemesh O”C 12 and Aruch Hashulchan don’t allow one to answer amen during Pesukei Dezimrah.
- Teshuvat Harosh (klal 4:19), Magan Avrham 51:2, Birkei Yosef 51:2, Kesher Gudal 7:26, Shalmei Tzibbor 67:1 SHulchan Aruch Harav51:3, Siddur Bet Ovad 11, Ben Ish Chai Vayigash 8, Mishna Brurah 51:8, Kaf haCHaim 51:3.
- S”A 51:3,215:1 and Rama 215:1. It’s permitted to answer the Shaliach tzibbur’s bracha if one finishes at the same time and it’s not an issue of looking like you are answering your own bracha. So writes the Bach 54, Magan Avrham 51:2, Beir Hetev 51:2, Shulchan Aruch HaRav 51:3, Mishna Brurah 51:3 and other Achronim.
- Halacha Brurah 51:12, Ben Ish Chai Vayigash 9, Kaf HaChaim of Rabbi Chaim Palagi 18:4, Mishna Brurah 51:2, Kesher Gudal 7:29,30 see footnote 17.
- The Magan Avraham (51:3) holds one can answer Amen during the bracha of Baruch Sh’amar since it’s a Bracha not mentioned in Talmud, so holds the Pri Chadash 51, Imri David Padir 51, Sh”t Levushei David Tanina O”C 16, Sh”t Hayshiv Moshe Titelbaum O”C 3, Mishna Brurah 51:2. However, Birkei Yosef 51:1 quotes Tur who quotes Sefer Hayecholet that Yishmael ben Elisha Cohen Gadol wrote Baruch She’amar and the mentioning of it in the Yerushalmi and Zohar. Thus, in the bracha itself one can’t answer amen, so holds Mishkenot Yacov O”C 64, Chida in Kesher Gadol 7:29, Mishna Brurah 51:2 in name of Chaye Adam 5:13, Igrot Moshe O”C 4:13, Shalmei Tzibbur pg 67b, Sh”t Zechur LeAvraham 3 pg 5b, Kaf Hachaim of Rabbi Chaim Palagi 18:5, Ben Ish Chai Vayigash 9, Tehilah LeDavid 51:1, Me’ain Ganim O”C 13:4, Torat Chaim Sofer 51:1, Biur Halacha D”H Im Siyem, Sh”t Meshiv Halacha 1:438, Sh”t Yabia Omer O”C 5:7(5), 6:6(3), Sh”t Yacheva Daat 6:3 pg 18.
- Kaf Hachaim of Rabbi Chaim Palagi (18:5) says one can’t answer any Dvar Sh’bekedusha during the Bracha. Yet Taharat HaMayim (Shuirei Tahara Ma’arechet 5:19, pg 54b) argues one should be allowed just as during Brachot of Shema. So holds Ben Ish Chai Vayigash 9, Kaf HaChaim of Rabbi Chaim Sofer 53:2, 54:7, Chesed LeAlafim 54:2, and Halacha Brurah 51:12. Mishna Brurah 54:3 quotes Chaye Adam 5:13 who forbids any interruption in the actual Bracha, but the Mishna Brurah says one could argue with this and leaves it as a tzarich iyun. Ben Ish Chai Vayigash 9 says one should say Amen Yehe Sheme Raba until Da’Amiran Be’alma and Sh”t Yabia Omer O”C 1:5, 6:8, Halichot Olam Vayigash 3 quotes Achronim who say one should only say up to Ulmiya. Concerning Barich Hu see footnote 23.
- Sh”t Ginat Veradim O”C klal 1:52, Sh”t Pardes HaGadol 5, Sh”t Zechur L’yitchak O”C pg 11d, Pri Megadim A”A 51:3 concludes with a Sarich Iyun, Mishna Brurah 51:4 all hold an interruption forfeits the bracha of Baruch Sh’amar and one should repeat it, Halacha Brurah in Birur Halacha 51:3 brings the Rashbetz in name of the Geonim that speech isn’t an interruption to answer a greeting of anyone or to greet someone who is due respect during Pesukei Dezimrah even between Baruch Sh’amar and the zemirot; and doesn’t effect the bracha, so holds Perach Soshan O”C klal 1:15, Korban Esheh O”C 2, Taharat HaMayim (Shuri Tahara Merechet 40:47), Sh”t Yabia Omer O”C 6:5(3). Minchat Aharon 12:3e, Kaf Hachaim 51:7 implied from S”A 51:4. On the other hand, Mishna Brurah 51:4 holds one should repeat, as do several other Achronim. However, Sh”t Yabia Omer O”C 6:5(3) says that had those Achronim seen the Rashbetz in the name of the Geonim they would have retracted their positions.
- See footnote 12 regarding Amen during Pesukei Dezimrah, Concerning answering amen during the beginning of Baruch Sh’amar, one can answer since one still didn’t begin the bracha with Hashem’s name; so holds Kaf Hachaim of Rabbi Chaim Palagi 18:4, Kesher Gudal 7:29,30, Mishna Brurah 51:2, Ben Ish Chai Vayigash 9 allows one to answer but afterwards one should begin Baruch Sh’amar again. Yet Kaf Hachaim of Rabbi Chaim Sofer (51:11) and Halichot Olam (Vayigash 4) say one shouldn’t repeat the beginning of Baruch Sh’amar.
- S”A 51:5 based on Tashbetz 204, Orchot Chaim (Meah Brachot 22), Kolbo 4, and Avudraham (Tefilah shel Chol) rules that the laws of greeting that apply to Kriyat Shema (S”A 66:1) also apply to Pesukei Dezimrah. Nonetheless, Sefer Chinuch (42) says since nowadays no one is concerned with be greeted for respect and it’s sufficient that one stands for them, one shouldn’t interrupt at all. So holds Mishna Brurah 51:12 and Halacha Brurah 61:4 against the Sh”t Tzitz Eliezer 2:1(3). Additionally, Kennest Gedola (66 Hagahot HaTur) limits the permit to greet to someone one hasn’t seen recently and not greeting him will cause hatred; another limition is that it’s only permitted to interrupt outside of shul. Many Achronim bring this as halacha including Magan Avrham 66:1, Eliyah Rabba 66:2, Solet Belula 66:2, Shalmei Tzibbur 97b, Mishna Brurah 66:2, Kaf HaChaim 66:3, yet, Halacha Brurah (Shar Tzion 51:26) argues since Shulchan Aruch quotes the Mishna without limiting the permit to a shul, it seems that he doesn’t hold of this chiluk.
- Sht”t Igrot Moshe 1:22
- Halacha Brurah 51:14 and Piskei Teshuva 51:14 define the part of Kaddish that one can answer as the first five amen’s however, the amen’s of titkabal, yehe shlama, al Yisrael, and oseh shalom shouldn’t be answered based on Magan Avraham 66:36 who says these amen’s aren’t an obligation but a Minhag. So holds the Ben Ish Chai (Vayigash 10, Shemot 6), Kaf Hachaim of Rabbi Chaim Sofer 66:23, Dvar Yehoshua 2:7, and Sh”t Yabia Omer 1:5, 6:8. However there is what to rely on to answer these amen’s as in Sh”t Igrot Moshe 4:14, and Sh”t Shoel VeNishal 4:26 that all amen’s can be answered during Pesukei Dezimrah. Concerning answering Amen Yehe Sheme Raba, Mishna Brurah 56:15 holds Ashkenazim should only answer up to U’lmiya, while, Halacha Brurah (Birur Halacha 51:7) quotes Me’at Mayim 19e, Shuiri Tahara 70:44, Minchat Aharon, Ben Ish Chai Shemot 6, Rabbu Eliyahu Mani in Yarchon Hameasef 3:36, Kaf HaChaim of Rabbi Chaim Sofer 56:33, and Sh”t Yabia Omer 1,5(10 and on), and Shulchan Aruch Harav 66:5 who permit one to answer until DeAmiran BeAlma. Concerning the 2nd amen of Kaddish Meorer Yishenim 21, Sh”t Igrot Moshe 4:14 say is just a minhag and shouldn’t be said, but Dvar Yehoshua 2:7 in name of Arizal this amen is of great importance, so holds Sh”t Yabia Omer 5:7(3). Concerning answering Barich Hu, Piskei Teshuva 51:14, Yalkut Yosef (Kriyat Shema U’Birchoteha footnote 18 pg 116-7) hold one shouldn’t say Barich Hu in name of Sh”t Levushei Mordechi 2:10, Sh”t Igrot Moshe 2:16, Sh”t Dvar Yeshua 2:7, Sh”t Tzitz Eliezer 11:3, Sh”t Az Nidabru 4:37.
- Magan Avraham 124:9 says any time one isn’t allow to talk one can’t answer Baruch Hu UBaruch Shemo, so holds Pesukei Dezimrah one can’t answer it, Sh”t Yabia Omer 2:4(6), Sh”t Yechave Daat 4:9, Mishna Brurah 51:8, Kitzur Shulchan Aruch 14:1, Chida in Tov Ayin 18:35, Shulchan Aruch HaRav 124:8,Sh”t Zechur Leyitzchak Hareri 7, Pekudat Elazar (beginning of 51), Siddur Bet Ovad (Pesukei Dezimrah 9) Aruch HaShulchan 51:5, Sh”t Afarkasta DeAniya 9, Peni Yitzchak Abulafiya (Brachot 1:43), Sh”t Ish Matzliach 22:2, Sh”t Lechem Shlomo O”C 36 against the Kaf HaChaim 18:13, Kitzur S"A of Rav Rephael Baruch Toledano, Volume 1, Page 111, and Rav Frankel in his comments on Shulchan Aruch 51.
- S”A 66:3 says one in kiryat Shema one can interrupt for Kaddish, kedusha and baruchu. S”A 125:1 holds one doesn’t say this even in a place where you can interrupt, even though the minhag is like the Arizal (Shaar Kavanot 3 of Chazarat Amida pg 39a) to say the entire passage regularly, yet in a place where one can’t interrupt one shouldn’t say the entire passage, so holds Kaf Hachaim of Rabbi Chaim Sofer 66:18 in name of some Achronim. Whether one should say Yimloch by the brachot of Kriyat Shema is a dispute of the Achronim and the majority opinion is that one shouldn’t say it. (see Hilchot Kriyat Shema Section II, Halacha _). Seemingly, the same law should apply to Pesukei Dezimrah since the Poskim compare the two for interruptions even though Pesukei Dezimrah is different that one can answer amen of brachot. Nonetheless, Birur Halacha 51:8 argues that Yimloch can be said since it’s a pasuk of praise that already instituted in Pesukei Dezimrah in the first halelluya. Imri David Padir 51 allows one to answer the entire passage of Kedusha since it’s praise but the Birur Halacha rejects it since the basic obligation to say it is a dispute between the S”A and Arizal. So holds Halichot Shlomo 6:11 in name of Rav Shlomo Zalman Aurbach, Sh”t Yabia Omer 1:5 in name of Sh”t Kiryat Chana David 2:41, but Rav Po’alim 4:4 is strict
- Sh”t Otzrot Yosef 4:4. There’s a dispute in the rishonim if the kedusha in Yotzer and Uva Lesion is a Dvar Sh’bekedusha. [The following hold it’s a Dvar Shebekedusha: Rav Amram Goan hashalem 1:15 pg 33) in name of Rav Tzemach Goan by Kedushat Uva Lesion and Rav Saadiah Goan by Kedushat Yotzer, Shibolei HaLeket Brachot 13 in name of many Goenim, Piskei Riaz (Megilah 3:3), Sh”t Rashba (1:7,5:9),Rabbenu Avraham Ben HaRambam testifies that his father retracted from his ruling (Tefilah 7:17) and held one can say it privately, while the following hold it can be said by an individual: Ravya 1:2,66, Talmedei Rabbenu Yonah 13a in name of some Geonim, Hagahot Maymonit Tefilah 7:90 in name of Rashi, Sh”t Maharam 143, Mordechai Brachot 69, Rosh (Brachot 3:18, Megilah 3:7), Tur 59, Orchot Chaim (Din Kedusha Meyushav 1), Ritva Megilah 23b. The S”A 59:3 writes that some say an individual can say it and some say not to and one should be concerned for this opinion and say it with the Torah reading tune. The Rama adds that the minhag is to say it as an individual.] Therefore, says the Otzot Yosef, since it remains a matter of safek we don’t interrupt in order to say it, just as the Bet Yosef 56 says in Pesukei Dezimrah one shouldn’t say the entire line of Yehe Sheme Raba because of the dispute.
- Sh”t Otzrot Yosef 4:4. There’s a dispute in the Rishonim if Vayavor is a Dvar Sh’bekedusha and needs to be said with a minyan. [Siddur of Rav Amram Goan 2 pg 79b, Sh”t Rabbenu Yosef Ibn Magash 193, Siddur of Rashi 545, Machsor Vitri 271, Or Zaruh 2:416, Hagahot Ashuri (end of taanit), Sh”t Mahariv 132, Orchot Chaim (Hilchot Sheni VeChamishi 2) hold it requires a minyan, but the Tur 565 holds it can be said without a minyan. (That is the explanation of the Tur according to Avudraham (siddur tefilat taaniot pg 88a) and Bet Yosef, against the Taz 565:5.)The S”A 131:6 rules that one can’t say it without a minyan unless it’s with the tune.] Therefore, it seems that Vayavor is a Dvar Sh’bekedusha and just like kaddish it could be answered in Pesukei Dezimrah. However, says Sh”t Otzrot Yosef 4:4, because of the opinions that say it’s not a dvar shebekedusha (such as the Tur and Talmedei Rabbenu Yonah) and the opinion that even divrei kedusha can’t be answered in Pesukei Dezimrah (Maharam), as well as the fact that the 13 midot are in the topic of praise but request, and that it may be an obligation but just a minhag the 13 midot are not to be answered in Pesukei Dezimrah. So holds Sh”t Shevet Halevi 9:1, Sh”t Kinyan Torah 4:9. yet the Mateh Efraim 619:37, Sh”t besel hachochma 5:1, and halichot Shlomo 6:17 in name of Rav Shlomo Zalman Aurbach are lenient.
- Halacha Brurah 51:18. Bet Yosef (beginning of 66) quotes Rabbeinu Yonah 13b who says one should wait and not answer Modim derabanan which would be a big interruption, so holds the Rabbi Avraham Aleshivli (father of the Ritva) 13b pg 298, Trumat HaDeshen 2, Avurdraham brings a dispute whether one should say just “Modim” or the entire paragraph. The S”A 66:3 says concerning Brachot Kriyat Shema to answer just “Modim” even in the middle of a paragraph. The Achronim explain the S”A as meaning one should answer the first three words. So comments Levush 66, Lechem Chamudot, Taz 66:3, Olat Tamid 66:8, Magan Avraham 66:6, Kaf Hachaim 66:22, Mishna Brurah 66:20. Seemingly the same should apply to Pesukei Dezimrah. Even though by Amen Pesukei Dezimrah is more lenient (Bet Yosef beginning of 51), Modim is just a Minhag [so hold Madeni Yacov Brachot 3:18(70), Tzlach ibid., Yeshuot Yacov 109:4, Yabia Omer O”C 4:21(4)] and not like Amen. Yet, the Eliyah Rabba 66:5 implies from Trumat Hadeshen 13 who says one can answer the first pasuk of shema with the tzibbur during Pesukei Dezimrah, that one can answer Modim Derabanan during Pesukei Dezimrah. However, argues Rav Ovadya Yosef in Yabia Omer 6:4(4), the Trumat Hadeshen is brought in the bet Yosef 65e and still the S”A 65:2 rules that one can not interrupt with shema even during Pesukei Dezimrah. Therefore the only reason the Eliyah Rabbah holds one can say Modim Derabanan during Pesukei Dezimrah is because he holds against the S”A by the first pasuk of shema (end of 65). Thus, Yabia Omer 6:4 holds since we hold like S”A by the first pasuk of Shema, here too we should hold not to say Modim Derabanan. Like the Eliyah Rabbah so Aruch HaShulchan 51:6, Kesot HaShulchan (Badei Shulchan 18:8 implied from Shulchan Aruch HaRav 66:5), Sh”t Minchat Yitzchak 9:8, and Mishna Brurah 51:8 hold one can answer the entire Modim Derabanan. However, Yabia Omer 6:4 (4) explains that these achronim are following their opinion that one can interrupt Pesukei Dezimrah to say the first pasuk of Shema. Siddur Bet Ovad (Dinei Pesukei Dezimrah 8), Sh”t Zechur LeYitchak Harari 7:5, Darchei Chaim 45a, Sh”t Yabia Omer 6:4 say to only say the first three words.
- The Rosh 20b writes that one should say the first pasuk when the tzibbur says shema. The Trumat HaDeshen 13 says one shouldn’t interrupt for shema since he’s not sitting idly but then concludes that one can interrupt Pesukei Dezimrah (and brachot shema) to accept the yoke of heaven. The Bet Yosef (65e) quotes this and in S”A 65:2 rules one can’t interrupt to say shema from baruch sh’amar and on. The Eliyah Rabbah asks on the S”A from the Trumat HaDeshen that one should be allowed in Pesukei Dezimrah to say shema. But the Bach and Taz explain that the Trumat HaDeshen’s conclusion was just a possible rejection. However the Bach says that the Minhag Ashkenaz was to say Shema, and the Taz says it’s only not allowed in Birchot Shema [In line with the Taz, Meorei Or Bear Sheva 22b say the acronym “Bet Shin” in S”A really meant Brachot Shema not Baruch Sh’amar] Ashkenazic Achronim rule like the Taz, including the Perisha 51:6, Atret Zekenim 65:2, Magan Avraham 51:4, Mor Ukesiah 65:3, Chaye Adam in Nishmat Adam 20:1, Shulchan Aruch HaRav 65e, Aruch HaShulchan 65:6, Mishna Brurah 51:8, Derech hachaim, Kesot HaShulchan 18:2, Shevet Halevi 1:40(2) However the simple ruling of S”A that one can’t interrupt in Pesukei Dezimrah is explained and held by Sephardic Achronim including Mamar Mordechi 65e, Chida in Kesher Gadol 7:32, Zechur LeYitchak Harari 7, Yafa Lelev 1:132(7), Siddur Bet Ovad (Pesukei Dezimrah 2), Chesed LeAlafim 51:2, Kaf HaChaim 51:6 ,Halacha Brurah 51:19.
- Birkei Yosef 244:1 quotes an anonymous sage who says one doesn’t need to show respect to a Talmid Chacham when he is involved in respect of Hashem, and rules against him because it is honoring Hashem to keep his mitzvah of “Mipneh Seva Takum”, so writes Rokeach 369, Sh”t Peni Mabin O”C 234, Sh”t Shlomo Chaim Zonenfeld O”C 48, Yalkut Yosef 1:77-8
- Rosh Brachot 2:5 agrees with Rabbenu Yonah who holds that during Brichot Shema one can interrupt for Dvar Shebekedusha. The Maharam (quoted by the Rosh) doesn’t allow one to interrupt praise of Hashem with a different praise. The Tur and S”A 66:3 holds like the Rosh. Magan Avraham (66:5) explains since one can interrupt for respect of person, how much more so for Hashem, thus one can interrupt for the Bracha of thunder. Erech Hashulchan 66e, Magen Giborim 66, Bear Heitev 66, Shulchan Aruch HaRav 66:4, Yeshuot Yacov 66, Tosfot Rabbi Akiva Eiger (Brachot 2 beginning), Mamar Mordechai 66:2, Solet Belulah 66:3, Aruch Hashulchan 66:6, Tiferet Yisrael Brachot 2:8, Sh”t Machat Yado O”C 1:7, Darchei Chaim 49a, Torat Yekutiel 35, Sh”t Yabia Omer 8:6(3), Sh”t Otzrot Yosef 4:5. However, Bechor Shor argues it’s only for respect of people because they would feel degraded, but for Hashem’s respect one doesn’t interrupt since it’s not degrading as one’s in middle of saying Hashem’s praise. So holds Mateh Yehuda 59:1, Chida in Machzik Bracha 66:3, Kesher Gadol 9:15, Shalmei Tzibbur 86a, Nahar Shalom 66:2, Minchat Aharon 12:4, 13:30, Sh”t Zechur LeYitchak 7:3, Siddur Bet Ovad Brachat Kriyat Shema 6, Meorei Or (Bear Sheva) 26b, Kaf Hachaim Palagi 18:8. See further Mishna Brurah 66:19, Chaye Adam 20:4, Sh”t Yabia Omer O”C 6:6(1). Even for those who are strict not to interrupt Brachot Kriyat Shema could be lenient in Pesukei Dezimrah since it’s a praise fitting the idea of Pesukei Dezimrah (as Bet Yosef 51 about amen).
- The Rambam in Sh”t Pear Hadar 147 says one can interrupt to put on talit and tefilin with a bracha. However, Bet Yosef 53 quotes the Kol Bo 5, who allowed the shaliach tzibbur to make a bracha on talit before yishtabach, and rejects this and rules in S”A 53:3 one can not interrupt between Pesukei Dezimrah and Yishtabach. Ginat Veradim O”C 1:52 understood S”A to mean one can’t interrupt even between the mizorim but quotes Rabbenu Yishaya who understood S”A to mean that only between Pesukei Dezimrah and Yishtabach one can’t interrupt. Divrei Mordechai 53, Kesei Eliyahu 53:3, Erech Hashulchan 53:1, Siddur Bet Ovad 9 pg 80a, Yafeh Lelev 53:3, Kaf Hachaim of Rabbi Chaim Sofer 53:7, Shulchan Aruch HaRav 53:3 agree with the Ginat Veradim’s understanding. Birkei Yosef 53:4 argues on the Ginat Veradim’s understanding because of the letter of Rambam. So holds Rabbi Akiva Eiger 53:1 (he leaves off with a tzarich Iyun),Sharei Kennest Gedola 53:4, Sh”t Korban Eshe O”C 2, Aruch hashulchan 51:6, 53:2, Mishna Brurah 53:5, Sh”t Shoel VeNishal 2:36, Netivei Am 51:3, Mekor Chaim 66:3, Sh”t VeYosef Avraham 35, Minchat Aharon 12:4, Sh”t Mishiv Halacha 1:409, Badei Hashulchan 18:23, Halacha Brurah 51:22. Sh”t Zechur LeYitchak 8 says had the S”A seen the letter of the Rambam he would have retracted.
- Otzrot Yosef 4:5. Bet Yosef 63e brings a dispute in the Rishonim about what part of Kriyat Shema is from the Torah; the majority of rishonim hold just the first pasuk is from the Torah. Pitchai Shearim 5, forbids one to interrupt Pesukei Dezimrah with Shema (more than the first pasuk) since Shema is not a praise. However, Otzrot Yosef argues that Shema is allowed just as Kaddish and Kedusha. Mishna Brurah 51:10 allows all three paragraphs (as he hold in 46:31). Even if it’s just to make the time of the Magan Avraham it’s allowed since it’s a Safek Deorittah for the first line and once you had to make a break one should continue. Sh”t Kennest Yisrael 13d allows one to even interrupt Shemona Esrah for saying shema in it’s time.
- See previous footnote for background. Ginat Veradim 1:51 quotes Rabbanu Yisheya who allows one to say Asher Yatzer, bracha on talit and tefilin when he returns between mizmorim and between Pesukei Dezimrah and yishtabach since once there was already an interruption anyway (to go to the bathroom). The Korban Eshe O”C 2 argues that one shouldn’t interrupt between Pesukei Dezimrah and yishtabach. Chaye Adam 2:1 writes similarly. Between mizmorim one can be lenient as holds Chida in Kesher Gudal 7:33, and Biur Halacha 53:3 D”H Ein Levarech says on the talit one doesn’t say a bracha at all since he had in mind to return. But between Pesukei Dezimrah and Yishtabach one should just wait. Yabia Omer 6:4(3), 8:6(7). Halacha Brurah 51:23
- Halacha Brurah 51:24. Sh”t Yehuda Yaleh Kobo O”C 4 allows one to say Kaddish Yatom during Pesukei Dezimrah, Sh”t Rav Poalim O”C 2:14 allows those who have the minhag to say chasi kaddish before yishtabach between mizmorim, however Sh”t levushei mordechai (tanina O”C 36, Kama O”C 112) forbids kaddish Yatom during brachot kiryat shema. Siach Yitzchak 25b:13, and Kaf Hachaim sofer 53:13, 55:22 forbid even in Pesukei Dezimrah but would perhaps agree by Kaddish Yatom. See further Sh”t Yabia Omer 7:10
- Sh”t Kennest Hagedolah O”C 51 says one can interrupt the end of Brichot Kriyat Shema for Vezot Hatorah. Emet LeYacov Elgazi (Dinei Hakamat Sefer Torah 2) agrees. However, the following are strict and don’t allow one to interrupt: Sh”t Zechur LeYitzchak Harari 7 pg 7d, Siddur Bet Ovad (Dinei Semichut Geula LeTefilah 9, Chesed LeAlafim 60:4, Kaf Chaim Palagi 18:13, Sh”t Nishmat Kol Chai O”C 4 pg 9d, Sh”t VeYosef Avraham 35 pg 218a, Me’at Mayim 4, and Kaf Chaim Sofer 66:47, Sharei Halacha Uminhag 1:63. [The Chida’s opinion is unclear as he writes in Chaim Shal 68, Kissei Rachamim (Masechet Soferim 14:14), and Kesher Gudal 11:21 not to interrupt for Vezot Hatorah but in Birkei Yosef 134:4 he brings the Kennest Hagedolah; it seems that he disagrees with the Kennest Hagedolah but just is quoting the Rishonim and Achronim, yet in LeDavid Emet 4:4, it sounds like he agrees with the Kennest Hagedolah.] Concerning Barich Sheme, Sh”t Meharshag 1:52(2), Siddur Bet Ovad (kriyat Sefer Torah 5-6, pg 100a), Sh”t Zechur LeYitzchak 7:5, and Sh”t Mayim Chaim Mashosh 27, hold one can’t say Barich Sheme. However, Shomer Emet 12:7, Vayismoch Moshe pg 5b, and Pri Sadeh 3:112 hold one can answer Barich Sheme. See further Sh”t Yabia Omer O”C 5:8, 7:9(2), Halacha Brurah 51:25.
- Imrei Yosher 2:171 says one shouldn’t interrupt since Kriyat Torah isn’t a personal obligation but a obligation on the tzibbur (implied from the leniencies of S”A 146, and explicitly in Ramban (Milchamot Megilah 1:5)) [however Igrot Moshe 4:40(4), (Biur Halacha 146 D”H Veyesh Matirim leaves in a Tzarich Iyun) hold that it’s a personal obligation.] Similarly, Sh”t Mayim Chaim Mashash 27 forbids even listening during Pesukei Dezimrah. Shomer Emet 12:7 says one can listen between mizmorim in Pesukei Dezimrah and not in Brachot Kriyat Shema, and Leket Yosher 1:18 says that once the Trumat Hadeshen came late and listened to Kiyat Hatorah during Birchot Kriyat Shema. Similarly, Sh”t Yabia Omer 7:9(2) allows one to stop and listen if one can’t find another minyan to hear Kriyat Torah.
- S”A 66:4 rules that one can’t interrupt kiryat shema to get aliyah even if called by name or he’s the only cohen. Magan Avraham says by Pesukei Dezimrah a cohen can get the aliyah. So holds Olat Tamid 66:13, Eliyah Raba 66:4, Kesher Gudal 11:23, Siddur Yavetz Siach Yitzchak 109b, Kaf Hachaim Palagi 15b:7, Sh”t Zechur LeYitzchak 7 pg 8d, Sh”t Veyosef Avraham 35 pg 220a, Tehila LeDavid 32b, Aruch Hashulchan 135:14, Sh”t Ish Matzliach 22. Siddur Bet Ovad(Pesukei Dezimrah 15) and Pri Megadim A”A 135:6 explain that this where he’s the only Cohen. Shaari Efraim 1:1 says not to ask for a misheberach. Yalkut Yosef 1 pg 73 says a Yisrael called by name is allowed just like an only cohen. Since someone who gets an Aliyah must read along with the bal koreh (S”A 141:2) so too in our case, so holds Shaari Efraim ibid and Tehilah Ledavid 282:1, against Siddur Bet Ovad (Pesukei Dezimrah 16) and Kaf Chaim Sofer 66:27 who say not to read along. Since it’s a issue of Bracha Levatalah if one doesn’t read along one should read along. See Sh”t Yabia Omer 7:8(3), Yechave Daat 4:11(58)
- Rama 284:4 rules that the one who gets maftir must do haftorah unless he doesn’t know how to read it as the Rivash holds it’s necessary and not effective after the fact. Sh”t Yabia Omer 7:8(22-3), Tehila Ledavid 282:3 and Sh”t Ayin Eliezer O”C 29 hold one should read the hatorah in our case. However Sh”t Kinat Soferim 122 and Kesot Hashulchan (Badei Shulchan 81:1) say one shouldn’t say the Haftorah.
- S”A 144:3 forbids rolling the sefer Torah in front of the tzibbur because it’s not respectful to the tzibbur. Therefore it’s like one is answering to a person due respect for which it’s allowed to interrupt even in shema. So holds Sh”t Teshurat Shy 1:128, Mishna Brurah 66:26, Sh”t Mahargash 1:48, Kesot Hashulchan (Badei Shulchan 19:7). If reading the Torah is okay where there’s no one else, so too it should be allowed for the same reason to correct a mistake. So holds Sh”t Lev Chaim 3:5. see further, Sh”t Yabia Omer 7:9 D”H Uleinyan pg 25
- There’s a dispute by Brichot Kriyat Shema whether one can add piutim brought in the Tur and Bet Yosef 68 between the Rambam, Rosh, and Ramah who don’t allow and the Rayvad, Rabbeinu Tam and Rashba defend the Minhag. S”A 68 rules some have the minhag to add piutim but it’s proper not to say them. Whether pituim are allowed in Pesukei Dezimrah is a dispute of the Achronim. The hold the tzibbur shouldn’t add piutim and should change their minhag so it’s not an interruption: Divrei Yosef 5e, Pri Chadash 68, Chida in Sh”t Tov Ayin 18:35, Mashcha Deravuta 112, Sh”t Divrei david meyeldola 24 pg 61c, Siddur Bet Ovad (Nishmat 7), Batei Kenisiot 124 pg 125b, Sh”t Yavikra Avraham (Makom Shenehagu 123c), Ikrei Hadat 4:21, Sh”t Mayim Chaim Mashosh 157. However others say the tzibbur shouldn’t change it’s minhag to take out the piutim such as the Sh”t Mahari kolon, Sh”t Adoni Paz 22c, and Pachad Yitzchak 136d. see further Sh”t Yechave Daat 2:7, Otzrot Yosef 4:6.
- Seemingly this should depend on the dispute of the rishonim whether Osek Min Hamitzvah Patur Min Hamitzvah applies if you are able to fulfill both mitzvoth. However one could argue here there’s more of a reason one’s chayav as the interruption is also a praise of Hashem and part of the mitzvah you’re involved in. On the other hand, one could argue that one should be exempt as it’s an interruption of his thought in Pesukei Dezimrah. Some hold it’s not an obligation and is just optional including Sh”t Mayim Rabim O”C 2, Torat Chaim Sofer 66:8, Sh”t Vayechi Yacov O”C 4 in name of Rav Chaim Berlin, Sh”t Yad Eliyahu Mekalish 9e, Sh”t Yabia Omer 5:13(5-6),6:21(3), Halacha Brurah 51:31. However Sh”t Nishmat Kol Chai 4 pg 9a, Sh”t Shalmat Chaim Zonenfeld O”C 49 holds one must answer not to be separating from the tzibbur but Sh”t Yabia Omer 1:5(7) argues on this.
- Magan Avraham 494:9 in name of SHlah, Eliya Rabba 494:12, Shulchan Aruch HaRav 494:17, Halacha Brurah 51:31 against the Chok Yacov 494:7.
- Halacha Brurah 51:16. In footnote 24, the overwhelming consensus of the achronim was not to say Baruch Hu UBaruch Shemo in Pesukei Dezimrah. However, the Tur 54 in name of Rav Amram Goan that one can interrupt between Yishtabach and Yotzer for a public need or to distribute charity against the Hagahot Miymoni Tefilah 7:12 in name of the Yershalmi that it’s an Aveirah to speak in between yishtabach and yotzer. S”A 54:3 quotes both of the above opinions. The Rama ibid writes that one can interrupt for blessing the sick or accepting someone for a court case since they are tzorech mitzvah, so holds Sh”t Meharshal 64. Similarly, the minhag is to say Shir HaMaalot during Asert Yeme Teshuva based on the Arizal (Darush L’Rosh Hashana 90a). Therefore, one should be able to answer Baruch Hu Ubaruch Shemo so hold Sh”t Rabbi Eliyahu Hamway 167c D”H UMekol Makom, Taharat Mayim 70:90, Lechem Shlomo O”C 36, Halichot Olam 1 pg 81, Sh”t Yechave Daat 4:9, against the Sh”t Peni Yitzchak 5 pg 170d. See further in Sh”t Shuirei Tahara 2:36, Sh”t Lev Chaim 2:109, Sh”t Kinyan Torah 3:91(3)
- Halacha Brurah 51:15. S”A 66:3 says one in kiryat Shema one can interrupt for Kaddish, kedusha and baruchu. Since whether one should say the entire passage is a dispute in a place where one can’t interrupt one shouldn’t say the entire passage, so holds Kaf Hachaim of Rabbi Chaim Sofer 66:18 in name of some Achronim. However, interruptions between Yishtabach and Birchat Yotzer are treated leniently as in footnote 44 and so one can answer the entire passage.
- Halacha Brurah 51:18. Interruptions between Yishtabach and Birchat Yotzer are treated leniently as in footnote 44.
- Halacha Brurah 51:19. Interruptions between Yishtabach and Birchat Yotzer are treated leniently as in footnote 44.
- Halacha Brurah 51:25. Interruptions between Yishtabach and Birchat Yotzer are treated leniently as in footnote 44.
- So that it doesn’t look like one is including Hashem in the statement about the other deities. S”A 51:6. Beir Gra 51:7 sources this in the Masechet Soferim 4:9. In the same pasuk, one should pause between Ki and Kol (so that kaf of kol has a dagesh), and Shamayim and Assa (so the mem isn’t swallowed). Thus, the pasuk should be read: Ki – Kol Elohei HaAmim Elilim – VeHashem Shamayim – Assa. Magan Avraham 51:5 in name of Shlah, Yad Efraim (Hagahot Tur), Bear Heteiv 51:4, Shulchan Aruch HaRav 51:7, Kitzur S"A 14:2, Mishna Brurah 51:14, Kaf Hachaim 51:7, and Halacha Brurah 51:32 agree.

- Kitzur S"A 14:2, Kitzur S"A of Rav Rephael Baruch Toledano, siman 11, laaws of tefila from baruch she'amar until yishtabach, seif 2, Mishna Brurah 51:1
- Magan Avraham 51:1 and Kaf Hachaim 51:1 write one should hold the tzitzit during Baruch She’amar. Chesed LeAlafim 51:2, Kitzur Shulchan Aruch 14:2, Ben Ish Chai Vayigash 7, Mishna Brurah 51:1 say that one should kiss them after Baruch SheAmar.
- Sh”t Yabia Omer 6:5(2-4),Yaskil Avdi O”C 8:42. The Sh”t Otzrot Yosef 4:2 proves from Sefer Pardes Gadol 5 pg 10a, and Rashi quotes by Shibolei Haleket 7 (on Shabbat 118b), that Yishtabach is compared to the end bracha of hallel and so one can say Baruch She’amar when he remembers since by hallel one can say the bracha on hallel when he remembers (Birkei Yosef 683:1, and Sh”t Kol Gadol 31). S”A 53:2 says one can’t say Yishtabach if he didn’t say Baruch She’amar and some Zemirot. Against S”A, the Pri Megadim says after the fact one who skipped Baruch She’amar can still say Yishtabach, so quotes the Biur Halacha 53 D”H Amar Baruch She’amar.
- Mishna Brurah 51:2
- Mishna Brurah 51:3
- Kitzur S"A 14:2 writes that the Ashkenazic practice is to stand for mizor letodah. Kaf Hachaim 48:1 quotes the Arizal as saying that one does not need to stand for mizmor letodah. Shalmei Tzibbur 68b, Keshur Gudal 7:38, Shaarei teshuva 51:9, Kaf hachaim palagi 12:18, and Shulchan hatahor 7 agree. See further minchat david 1:52, Rivivot Efraim 4:22. Yad Aharon (1 Hagahot Tur), Siddur Baet Ovad 3, Shulchan Aruch Harav 1:14, Siddur Yavetz, Derech Hachaim.
- Rama 51:9, bet Yosef 51 in name of Orchot Chaim (meah brachot 26) say the minhag isn’t to say mizmor letodah on Shabbat and Yom tov but the Tur disagrees. Instead we say mizmor leshabbat as mentioned by the orchot chaim (quoted by bet Yosef ibid.). Concerning the first pasuk on Yom tov, the orchot chaim holds not to say it, so says in Siddur Rav Sadyah Goan 120, Sefer minhagim of Rabbi Yitzchak madura says to say it even on Yom tov. So holds Pri Chadash 51:9, Shaarei Knesset gedolah (Hagahot bet Yosef 10), Olat tamit 51:2, Eliyah raba 51:12, Bear Heteiv 51:10, Shalmei Tzibbur 68c, Ruach chaim 51:8, Mishna Brurah 51:21, Kaf Hachaim 51:49. see Sh”t Yabia Omer O”C 8:11(14 D”H Beshabbat)
- Knesset gedola (Hagahot hatur), Magan Avraham 51:10, Shaalmei Tzibbur 68b, Minchat Aharon 69c record the minhag to say it on rosh hashana and some would also say it on Yom Kippur. However, Pri Megadim (A”A 10), Sh”t Rav Poalim 3:38, Kaf Hachaim Sofer 51:50, Mishna Brua 51:21, Kaf HaChaim Palagi 12:19 in name of the Arizal. See Sh”t Benai Levi 3. Concerning Erev Yom Kippur, Rama 51:9 says not to say it, but Knesset Hagedolah(Hagahot Tur), Shaarei Knesset Gedolah (604:5 Hagahot Bet Yosef) say the minhag is to say it. So writes Pri Chadash 604, Shalmei Tzibbur 68b, Kaf Hachaim palagi 12:19, Kaf Hachaim Sofer 51:52
- Rama 51:9 based on Sefer minhagim (hilchot erev peasch pg 38), as well as pri Chadash 429:2, Siddur Bet Ovad, Siach Yitzchak say not to say it. Bet Yosef in name of Tur, Shaarei Knesset Hagedolah (hagot bet Yosef 8-9), Sh”t bet david O”C 441, Sh”t Maaseh Avraham O”C 19, Shaalmei Tzibbur 68b, Rov Dagan 154b, Zecher LeAvraham 429, Kaf Hachaim Sofer 51:51, Kaf Hachaim Palagi 12:19, Chazon Ovadiah 2 pg 6, Sh”t Yabia Omer O”C 8:11(14)
- Sefer Minhagim of Rabbi Isaac Tirna 82 says not to say it, but Sh”t Maharil 64 says it’s a mistake and it should be said. So holds Olat Tamid 51:2, Knesset Gedola (Hagahot Tur), Magan Avraham 51:11, Bear Heteiv 51:10, Shalmei Tzibbur 68c, Kaf HaChaim Palagi 12:19, Mishna Brurah 51:21, Kaf Hachaim Sofer 51:53.
- S”A 51:7 based on Talmidei Rabbeinu Yonah 23a D”H Kol HaOmer. Orchot Chaim (Tachanot Vemizmorim sh’acher shema esreh 3), Sefer Eshkol (Mehuderet Rav Aurbach 24:53), Birkei Yosef 51:5, Siddur Rav Amram Goan 103 say we Ashrei is said 3 times so that if one didn’t have the first time he can have kavana the next time. However the Levush 51:8 says when one remembers one must repeat the whole mizmor, on which many achronim (Eliyah rabbah 51:6, Magan Avraham 51:6, Pri Megadim A”A 51:6, Mor UKesia, Solet Belula 51:5, Yeshuot Yacov 51:1, Shulchan Aruch Harav 51:8, Birkei Yosef 51:1, Siddur Bet Ovad 51:3 and Kaf Hachaim Sofer 51:32, Halacha Bruah 51:33) disagree based on the Talmidei Rabbenu Yonah that one just repeats Pote’ach. Still, Chaye Adam 18:2 and Mishna Brurah 51:16 hold when one remembers one should repeat from Pote’ach until the end. The Kaf Hachaim Sofer 51:33 says one shouldn’t interrupt to repeat Pote’ach in Pesukei Dezimrah since one can say it with Kavanah after Shemoneh Esrei and repeat it there if needed. However many allow one to repeat it even in Pesukei Dezimrah. So holds Ben Ish Chai Vayigash 12 and is implied from many posikim. Therefore Sh”t Yabia Omer 5:6 says one should preferably say it between mizmorim
- Rov Dagan (Ot Letova 24:2), Chaim LeRosh (Birkat HaMazon 8 pg 78b). See further in Sh”t Torat Lishma 31, Ben Ish Chai Vayigash 12, Pekudat Elazar 51e, Sh”t Kiryat Chana David O”C 1:13, Tzitz Eliezer 12:8, Milta Betama 72, Sh”t Shaarei Tzedek Chirari 2:20.
- Tur 51 writes of the practice of the introductory pasuk Ashrei from Tosfot Brachot 32b D”H Kodem. The Bach 51 brings the second introductory pasuk of Ashrei against the Rokeach. Magan Avraham 51:7 agrees. Bet Yosef 51 and Rama 51:7 bring the ending verse VaAnachnu.
- Concerning repeating, Rama 51 brings the practice based on Machsor Vitri 1:6, against the Orchot chaim who says not to repeat Hashem yimloch. So holds Magan Avraham 51:9. The source to read the targum of Hashem yimloch and ki bas Sus is the Arizal (Shaar Kavanot 31b), Ben Ish chai vayigash 14. however the Mishna brurah 51:17 quotes the Gra who says not to say ki ba sus.
- Shaar Kavanot (Tefilat Shachar 18c) Pri Etz Chaim (shaar zemirot 6), Magan Avraham 51: 7, Shalmei Tzibbur 70a, Keshur Gudal 7:43, Siddur Bet Ovad 1, Mishna Brurah 51:19, and Kaf Hachaim 51:44. See Sh”t Yagdil Torah 1:21.
- Tur 559 records the minhag not to say Az yashir on Tisha BaAv. Bet Yosef says the minhag was to say haazinu instead of az yashir, so records ben ish chai Devarim 26, but the Darkei Moshe 559:6 says the minhag is to say az yashir as usual, so records Chesed LeAlafim 51:11 so was the minhag of yerushalim according to the practice of the Arizal. See further Sh”t Olat Shmeul 79, Sh”t Yabia Omer Y”D 4:32(3)
- Orchot Chaim (Meah Brachot 32) quotes by Bet Yosef 51, Magan Avraham 51:7, Eliyah raba 51:7. see ketonet or vayechi d”h ve’amarti.
- Solet Belula 51:4 says one should pause since adirim isn’t referring to the water but the Egyptians, Pri Megadim M”Z 51:1, shalmei tzibbur 70c, ben ish chai vayigash 14, Mishna brurah 51:17, kaf hachaim 51:39. However the Sansan leyair 35 argues from Rav Yehuda halevi, Rashi and Mechilta on the pasuk. See Sh”t Levushei Michlol 4:41, Rivavot Efraim 2:34, 3:52, 4:23
