Q. I have seen trumpet musicians play most beautiful concert and other music using a shofar, Is that permitted?

A. If the shofar was already used for the mitzva of Tekias Shofar, we mentioned on question 4426 above that there are some issues to be concerned with regarding the honoring and disposal of it.

If the shofar was not used for a mitzva purpose, Horav Shlomo Miller Shlit’a maintains that in principle it could be used for music since that shofar does not have any Kedusha or holiness. Horav Aharon Miller Shlit’a is similar.

However, they cautioned that if the music or event is frivolous or unethical, a shofar should be avoided.

Horav Kalman Ochs Shlit’a maintains that; ” ערוך השלחן  תרפא סעיף יב   התקיעות מעוררים מדות למעלה”.
Therefore it would not be wise to blow shofar for entertainment.
