I posted this on a blog other than this one, but I hope it helps! I based it off of what I think I would have, since I know how to play a hell of a lot of instruments.

Musical Manipulation

The user has tattoos on their fingertips, which when all five fingers of one hand come into contact with an instrument, they start to control it. Meaning, that the sound waves it produces, they can use them in different ways. Different instruments have different effects. Electric guitar would be purely attack, having little precision and could damage the user from recoil if not used to it. Violin is a more dialed back attack instrument, precision being key and gives more movement. Bow could be used a a sword. Flute could be a pure support instrument, giving energy and strength to allies in combat. So on and so forth.

The drawbacks would be that since the instruments become somewhat a part of the user, injuries done to the instrument would also harm the user. So if a violin bow snaps, it feels like they broke a finger or something, and if a guitar neck snaps, it could make them cough up blood. Also, manuverability would also be heavily reduced when playing the instruments.
