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?
Des is in a band! He considers his guitar almost an extension of his body at this point (and is really good at playing it!)
Also, he does all the uncleans in his band's songs! (screamo :'D)
Reinku, my sona, is a flute player like myself (obviously). Also Kimiko is an above-average singer
Odyssey is literally a bassoon, so of course he's musically talented - he's missing a keypad though, I believe it's T3.
Felix is my truesona so he's literally me, and so of course he plays the bassoon, flute, tenor sax, piano, dulcimer, and fife.
Stephen is also quite literally a tenor sax, so he plays great as well.
last dude - Will plays bassoon and bari sax.
i love musical characters so much, i'm a band kid so what can i say? \o/
jackie boy had an electric guitar before the apocalypse hit his world. he has an acoustic now that he plays anytime he has the chance and he also sings super well ! he's a dumbass, but he has a real ear for music and can sing/play by ear just about anything after he's heard it only a couple of times.
