"Started out in percussion," Billy said, more than willing to talk about music any time, any place, with anyone, regardless of how much pain it caused him. "But turns out there are a lot of guys better than me, so I ended up singing." He smiled. "I can--well, used to--play some of everything, and it helps when you're putting music together. Probably go back to piano a little heavier, don't have the dexterity for strings anymore." He thought about it. A piano had the basic melodic layers for everything, even percussion if you can pedal and play it right. He could try banging some more on a piano and see what Merc made of it. There was a piano at his parents' house, though it wasn't the one he learned on when he was a kid. He didn't need a real big one, just something to experiment with. "Huh. Maybe when the floor is done." Casting his eyes around. "Maybe stick it over there."
