Oh boy... Derrick will probably mention his powers to Brook as a warning at the beginning. His first thought upon meeting his instructor is "The hell is up with his hair?" ._. Being a skeleton doesn't bother him really nor all the puns. He doesn't say or show any of this though.

And then he will spend the entirety of class glaring at an instrument (let's start with a trumpet) instead of playing it... in a corner as far away from everyone as he can be. Also, just being lost in general because he knows nothing about instruments or playing music and wonders how he let himself get talked into taking this class when he's a danger to everyone else and knows nothing.

... I swear eventually Derrick will like this class... |D;
