Shaliach Tzibur

From Halachipedia
  1. The Shaliach Tzibbur may use secular tunes for Kaddish and Kedushah, though it is preferable to use tunes that the words to which have already been forgotten.[1]
  1. See Yechaveh Daat 2:5 where he explains that the main issue with secular music is the words, so it's best not to pick a secular tune that will remind the Tzibbur of the words to the song. Rather, one should use a tune that nobody remembers the words to, as it has then come from the Sitra Achara to the Sitra deKedushah
