Making a living out of music is difficult, but it's not that hard to make pocket money from playing in bar bands. You don't need much in the way of technical proficiency, but probably you'll need to do a lot of playing (esp with other musicians) to learn things like stagecraft and timing before anyone will give you a paid gig.

You can get paid, but it on its own most likely won't cover the costs that go into creating it. But it's often worth that cost anyways

Yeah, it's a side business for me. Pre-covid, I was making $10-15k a year playing on the weekend. Kind of a fun thing to chase too, as if you're playing paying gigs you get to play with better musicians,
