[AX7221]

I just know the basic strumming for the riff, but i saw someone play it one time with very interesting strumming so i was wondering if people knew variations of the riff that they would like to share

the first part alternates between open on E with second fret on A and open on E with fourth fret on E. then it goes between open on A with second fret on D and open on A with fourth fret on D. It goes back to the first part, then for the next part is goes back and fourth between second on A with fourth on D and second on A with sixth on D. then at the end it keeps E open and plays 2, 4, 5, 4, 2, 4, 2 on A. If thats confusing then i botched it, its a basic riff and the mp3 should be much much much clearer

That is called a blues shuffle Ax. There are countless variations. You play the root of the chord on the bass or lower string at the same time as you play a 5 interval then you go up to the 6 interval and back down or you keep going and add a b7 before going back down. You can also replace the last notes of the pattern with a muted strum before starting the pattern again. You can break up the pattern like SRV playing The House Is Rockin. It is endless.
