I like your idea
@WhistlingBadger . Maybe it's the old punk in me, but people should have a chance to make music, even if they aren't great at it. Even if the people who join up have rudimentary skills, that first song that sounds more or less like it's supposed to is magical as a feeling. I was once involved in starting up a fiction writers' group in a blue collar community in a time of high unemployment. 18 people showed up because they wanted to write prose, poetry or songs, and after a year, the majority of them had published something. They wanted to do it, and if they stuck with it, they did it.
None are writers now, but who cares? They accomplished a thing they wanted to do, and who knows where that confidence took them?
Music, writing, painting, all arts - even the art of creating aquascapes - people need that. Give those people musical structure to work with. You have the ability, and they have the need.
I just discovered one of my neighbours up the road had surgery and lives alone. She's a visual artist in her nineties, so I've dropped over to clear snow, and help out a bit. Yesterday I was listening to her as I started up the wood stove. She tries too hard to convert me to her religion, but in between biblical stuff I hear the dedicated artist. She's far from rich, but with her art, she's made herself a rich life. I fed the cat, gathered the dishes and listened to the sparks. Creative people have to create. They may not get rich but they get interesting.
