It's totally a hobby , she's by no means professional but Caph here plays guitar (acoustic only)
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?
Justin here is a skilled guitar player and singer, and he enjoys traveling and playing for people while taking in new sights.
Heeere's Tia, the bard of the group! Despite her being in a fantasy, somewhat tolkien-inspired setting, her music style is a lot closer to Elvis than medieval. She can really get into it and loves jamming out when she thinks people arne't looking (or sometimes when they are and she gets carried away).
Nokken uses his violin's music to hypnotize his victims, but even when he's not using his magic he's still an expert in playing the instrument.
Theo is quite good at singing and playing guitar, and he's also skilled at dancing and whistling as well.
This guy is my only musically talented OC (for now). He sings and plays guitar and violin, though he's mainly interested in punk music. In one AU I have he actually has a YouTube channel, but he's never been in a band.
Portia can hold a tune, but she's much better at dancing. She also plays french horn for her band class and does pretty well with it.
