[Harp-L] re-tuning to Spiral (Circular)

[Robert Hale <ynfdwas@xxxxxxxxx>]

I have searched archives, but not found posts about which key plates are
being used to retune to each Spiral (circular). I'll contribute some
successes if it will add to what has already been done.

No other tuning can replace the significant historical contribution of the
diatonic in American blues, but Spirals are especially powerful in
pentatonic minor keys! I find Spirals effective for country (major)
melodies, Celtic, and as an extension of the Melody Maker.
