Watch the Deep Soul online guitar lesson by David Santos from 50 Bass Grooves You MUST Know
This is a one measure bass line that serves as an ostinato, which is defined as a phrase or motif that is persistently repeated with the same musical voice. The chords change over the repeating bass line. The bass notes that were chosen to create this ostinato figure do not indicate or define a major or minor tonality therefore many harmonic and melodic choices will fit over the top of it. Work on your right hand.
