Hi
I have just started looking at playing Lampedusa arranged by Derek Gripper:
https://youtu.be/-B0Oki7vS90
The tuning is DADF#BE, so it definitely looks to favour songs in D.
The key signature however portrays the song in the key of A major, with sharps on F, C, and G.
Then the song continually resolves to D throughout.
It is obviously Malian, and not traditionally Western, but can someone explain some of the theory here. Why the key of A but then a tonality of D.
Is it just a different scale being used for D with 1, 2, 3, 5b, 5, 6, 7?
