[Harp-L] What key is the band in?

[Robert Hale]

Also useful, but rare among blues players and jammers, is the fingers up or
down signal, denoting the sharps or flats in the key. (Does it have a
better name?)

C = fist, no fingers
G = one finger up, one sharp
D = two fingers up, two sharps
A = three fingers up, 3 sharps

F = one finger down, one flat
Bb = two fingers down, two flats
Eb = three fingers down, 3 flats

I am around a few players who will call out verbally "One up" for G, for
example.
I don't expect it to catch on, but it sure is effective when it is the
common language at the time.
(Then follows some confusion about calling the chord changes in numbers!)
