We can add more later and for other characters... just wanted to get some up.
ps... I'm not sure what instruments you wanted Chris to play, I figure they both started with piano, she went to Violin. Topher does Piano, Guitar/Bass, Some Drums and will learn Trumpet out of boredom XD

~Yea they both started with Piano, Chris switched to strings, mostly violin, and that's her main but she also learned more of the woodwind instruments. Saxophone would be her second favorite and Flute her least fave. She also knows how to play Clarinet but she don't touch it often. Probably picked up a bit of brass knowledge through Topher. Like if she had to she could play it but normally she wouldn't. She also probably dabbled a bit with other percussion instruments: marimba and timpani. Maybe able to pluck out some stuff on guitar but that's about it. ~Krazy
