WAV - there's nothing in the least bit traditional about chromaticism, on the contrary; the chromatic tempered scale has been used in the oppression and subjugation of indigenous musical systems & cultures the world over (including those of the British Isles) so what sort of bland boring corporate global musicality are you representing by playing an instrument which a) in in no way shape or form traditional to traditional English music and b) which represents the very music system by which other world & ethnic musics are so ruthlessly impoverished. There is nothing either traditional or English about this instrument; it is vile, unnatural & perverse, and plastic to boot, so donate the fecking thing to your nearest charity shop and invest in a nice Clarke's C (the original key) or one of Dave Shaw's more developed versions of the Clarke's concept, still manufactured, I believe, in County Durham...
