I'm a sucker for anything related to music, so are any of your characters in a band? Do they like to sing (whether they're any good or not)? Can they play an instrument? Lay 'em on me. :)
I'll start off-- most of my characters are musicians, because they're from a story about a battle of the bands contest, but this guy is Izzy, the lead singer/lead guitar in a punk band in the contest. He's more loud and enthusiastic than he is good, but that's all you need to be punk, right?
Mishka's in a band and plays the keytar. They can probably sing too but prefers to stick with instrumental.
There's also Neil who is literally named after Lemon Demon so. He's a growing musician who can probably play a lot of instruments - well, he can play them but nobody said he was good at them. He's best at song writing.
Even with his gritty, war torn outward appearance, Dayrn is a pretty sensible guy. He plays the Lute as a past time when he isn't guarding a post or being abducted lmao. Him playing instruments isn't a huge part of his character, but when he DOES play, he usually likes to play alone.
Both Carolina and Hector are in a travelling performance band. Carol is the lead dancer and can also sing, with a preferance for French songs.
Hector is more inclined towards intruments, and can p,ay pretty much amy genre. But he prefers more rustic or upbeat tunes, like country, folk, and occasionally tradisional music.
