[Harp-L] Re: Modes, keys and positions (John F. Potts)



Thank you John,  for taking the time to reply with such a clear description.
Much appreciated!
I'll sit down and create some form of a chart / poster from your
information, to which I'll add other gleanings such as the circle of fifths.
By nominal key I meant to indicate the named key of the harp (which can play
in different keys) as purchased, i.e. 'a "C" harp'  etc.
Until now I've just selected the harp that suited the tune and played it
in what I call "Low, mid and high" ranges, bending where necessary but have
begun to suspect there's a great deal more potential.

Best regards
Geoff Atkins
