What's the word for someone..

[heathfield]

Someone who plays imaginary musical instruments? (Not just guitars). I heard it on the radio years ago, but immediately forgot it.

[SaxyJag]

Isn't it just an air whatever-it-is?

[heathfield]

Nope, there's a proper word for it.

[:Ace:]

A Mental?

[MacGuffin]

very sad?

assuming this is a crossword, do you have any letters

[heathfield]

PC - not a crossword, just a word.

[LotusEater]

I believe it's a condition linked to Tourette Syndrome whereby the person has the compulsion, for instance, to play an invisible 'piano' on a table-top. Can't for the life of me think what the term is, though. May be totally wrong.

[heathfield]

Tourette's? Hmm. Compulsive, yes. Disorder? I hope not! Oh well, I'll just keep on wondering... Thanks all. (Can't believe you've never done it, ace!) ;-)
