By the way, if you start at D and count up five steps (D-E-F-G-A) you
arrive at A, which is second position. Count up five more steps
(A-B-C-D-E) and you arrive at third position. Keep counting up five
steps and you get all 12 positions.
Third position, E on a D harmonica, has a home chord in Draw 4-5-6 and
8-9-10. The scale has a flat 7th and a flat 3rd, known as the Dorian
mode. A lot of SCottish and Irish tunes use this scale, in various
keys. The Sailor's wife, Johnny Wilmot's Fiddle, the Warlock, Sleep

Renwick's Ferret, I lost my love, There Came a Young Man, Drummond
Castle, Eilean beag donn a' chuain, among many others.
