Nice little tune.
Simple and solid intro.
Two places on YouTube to look at for ideas:
For this Lesson File I provide the basic rhythm.
The intro licks.
And a few idea for adding licks in between the rhythms.
It is in the key of E, though it is not explicitly implied.
The three chords also fit in to the key of A.
The differences between the scales are
- E has D#
- A has D
The D or D3 is not used at all as far as I can tell, maybe it is in there somewhere.
For that reason, when soling etc, try and avoid playing either D or D# to keep the vibe the same, slightly ambiguous.
