Hey Jack,

Fiddle and violin are the same words. A viol is an instrument with 6 strings. A violin is a little viol ("in" being the diminutive-having 4 strings). So fidheal and viol are the same (f is an unvoiced v).

It seems to work, but it hurts your head. To hear the sound, go to: http://www.youtube.com/watch?v=a3scougnTfA

You can make or buy one of these things (they still sell them in the Eastern block countries) and play some tunes. You can only play in one "key" but as you end on different notes, you have different "modes.". The 7th partial is really weird.

Cheers,

Andy
