Shambles - You're dead right again.By which I mean, we're in agreement.

The Musicians of Bremen were an ass, a dog, a cat and a cock.That's the kind of company I feel at home in.

There's people who play instruments. There's people who make music. You might be great at making music and not too good at playing an instrument. It's quite often the other way round. If you're lucky, and we're lucky, you might be good at both. You're a musician in any case. (I suppose if you combine being no good at playing an instrument and being no good at making music you might be termed no musician. But I'd calll you a so-far-unsuccesful musician. Possibly,let us hope, a struggling musician.)
