[Harp-L] 1st through 4th hole blues scale

[Bill Hines <billhines4@xxxxxxxxx>]

In the Exploring 3rd Position book/CD, David Barrett has a page toward the
end with the 1st through 4th hole D blues scale - 1D 2D" 2D 3D'" 3D" 4B 4D
(or D, F, G, Ab, A, C, D) played on a D harp. But isn't that first position
- D blues scale on a D harp? Just confused by that since it's a book on 3rd
position!

TIA, Bill
