Today I was reading Nehemiah 12. There is an entire list of Levites who were in charge of the songs of thanksgiving. Verse 29 says that "the singers had built their own settlements around Jerusalem." It talks about how they divided into 2 choirs and walked around the top of the wall. Then they sang in response to each other and there were trumpet players and other musicians, as well.
Verse 43 says "and the joy of the people of Jerusalem could be heard far away."
I can just imagine what it sounded like.
