[@SiliconColt] I'm here, I just didn't get any notification from the mention in the OP post for some reason...

I'm ok with everything discussed so far, here's my character:

Plays the Flute and Piccolo

HC: Can create structures and creatures with sound and control them with the melody from the instrument, when playing the Piccolo the structures and creatures are stronger because of the higher pitch of the tone. 

Trouble: Has asthma/other breathing problems so is bad at athletics and can't play for extremely long amounts of time. Structures and creatures break or disappear when they stop playing.
