Let me clarify so that there is no confusion.
Yes, Max Bruch wrote his classical piece Kol Nidre which was based on the Aramaic/Hebrew liturgical prayer Kol Nidre and it’s melody.
However, it was based on the Ashkenazic version of the Kol Nidre, not the Sephardic.
Bruch took the music and adapted it for musical instruments. He created a written musical score.
