Lawrie,

Believe it or not, I actually anticipated this exact response from you. LOL.

May I propose a scenario for you?

Let's say you're at a social event and you meet someone who happens to be a professional singer,(but they don't play an instrument), and you don't know that.

You ask them what they do for a living.

(I'll concede the voice as an instrument for the sake of this discussion.)

Would their answer be singer, instrumentalist or musician?

Bob
