TS says not from the musicians' point of view. General public.

Look at it like this. You're bringing your BF to meet your parents. He's an ex-con who just got out. But you already lied and told them that he's a professional musician. So he's coming to dinner tonight, he turns to you and ask "should I say I'm a drummer, guitarist, pianist, or conductor?". Which one is going to impress them most?

thank you
