Shavua tov, all. Here with a question about halakha.
I saw someone make the point online that according to traditional halachic sources (Gittin 7a, M”T Taanit 5, S”A O”C 560), it’s actually forbidden entirely to make music using instruments or even to enjoy music at all after the destruction of the Beit haMikdash (with machloket as to whether this applies equally to vocal and instrumental music, or vocal music in the process of “making merry,” so to speak). This pronouncement is made without reference to the specific mesorah of the Three Weeks. Obviously, we don’t really hold by this today, and music is a part of Jewish life in pretty much every community. But, I’m wondering if anyone has sources as to why these prohibitions aren’t followed in the modern era.
