I would say that that's the wrong question. Or, perhaps, a secondary question. The primary question, surely, is "WHAT is a musician?" The trite & obvious answer, obviously, is "Someone that makes music!" That it's trite & obvious doesn't mean it's wrong, though it might suggest that a more thorough & considered answer is a good idea...

But only if you know (which really means "If you have an idea what...") what a musician is can you then answer "Is an X a musician?" Is a drummer a musician? Is someone who programs a computer to play music a musician? Is a composer a musician? A composer may not be able to play a note, but they *create* music. I have often suggested that classical musicians are not musicians, they are technicians - they don't create, they interpret. Like actors. Yes, I am very well aware that that is far from entirely true, but for the sake of the point... They are highly skilled technicians. So is a stonemason or a woodcarver. They do what they are told to do. They play the notes, speak the words, make the design that they are GIVEN.

So are they musicians, etc; artists? Is the man on the pneumatic drill a musician? Sounds like that have been incorporated into modern compositions. Is s/he a musician only if they drill to the composer's order? A musician if they are recorded without knowing?

The first question MUST be "What is a musician?"
