It's probably not the same, but I am in an orchestra, and a casual music group, and a cello ensemble, and in all of these I LOVE making music with other people. I think it scratches a social itch without having to employ those skills that are harder for us. There's some kind of communication that goes on when you're playing, where you react to how someone else is playing, where are giving an invitation to play the music with a certain dynamic or tempo, and you can join them or try to play in an opposite way if you don't agree. In the casual music group, everyone might start to slow down as though it is the last time through that piece but someone could determinedly play up to tempo and then start playing again, and maybe someone who also wanted to play again but wasn't going against the majority decides to keep playing as well and support them, and then others relent and join in and everyone ends up playing it again. Or sometimes that bold person isn't able to convince the others and they falter off after two or three bars. It's interesting when they even get 2 or 3 others to join in but the others are stubborn and won't join in and they still end up faltering even with the support. It's like a huge conversation where everyone eventually gets convinced and plays one way. But one with no body language and no words, and usually no eye contact. All the communication is through your ears. It can be beautiful and I love it.
