Gm7

note >> this is the original notation
of this tune. the etude is rhythmically different. also try different grooves, play parts of the lick "out" - one fret higher or lower,
and get back into G minor again. the chord progression in the 1st bar is Gm9 - Dm7 - Dm7/11 , of course.
it could also be Gm9 - Dm7 - Ebm7 - Dm - Dm7/11 . check out any arpeggio u use to play, and combine it with this ... :-)
