‘On the Road Again’ was recorded by the American blues-rock group Canned Heat in 1967.
The distinctive harmonica solo first played by Alan ‘Blind Owl’ Wilson utilizes a special tuning adjustment. Played on a harp in key A in cross/2nd position E, adjustments to draw reed 6 are made by raising the pitch of the reed a semi-tone from F#-G.
I show it below in Cross key of G (for comparison with other tunings) and also in Wilson’’s Cross key of E.
