Drew is primarily a guitarist who also knows how to play piano and tenor sax. He does like to sing and write songs, too, but he's usually too embarrassed to perform his own music in front of anyone else.
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?
Chanson is my most musically talented character. Not only is he trained in opera, he's also mastered the pipe organ and the violin. His unique ability also centers around his musical talents.
Clef is a composer and pianist! Kind of crazy that his appearance just so happens to perfectly suit his chosen career, unless he only became a musician because he felt like he had to... I dunno, he isn't very developed yet.
A bard! Irma has been playing music since she was an elfling. She knows how to handle a few different instruments but favors her lute the most.
