Whoa, extensive, thanks FR.
I'd probably get a simple one for learning, probably C major, but my goal is to use it in my band, and we play with drop D instruments and so usually end up in D minor. So in theory I'd need a harp to play Dm, or D blues or something similar (if I could throw a flat fifth in there I'd be loving it
). My musical theory isnt quite strong enough to work out which harps I could do this on, but I think there'd be at least diatonic harp that
wasn't Dminor that I could play Dminor on, or I could just get a chromatic one I suppose.
After a glance in the net, it definately looks trickier that I first imagined... ah well the bigger the rewards I suppose
Thanks again for your input all.
