Two questions I hear most often from students are, “How can I become a better rhythm player?” and “How can I learn to connect different scale positions effectively when soloing?”

To me, these two aspects of playing embody virtually the same concept: whether you’re laying down a rhythm part or taking a solo, you should have the freedom to play musical ideas all over the fretboard without feeling confined in any way.

Just as one studies all the patterns associated with a specific scale for soloing, one must also study chord construction, inversions and chord types, to be able to improvise rhythm parts with the same feeling of authority and freedom as when soloing.

To address both issues, we’ve spent the last several columns examining a repeating I-IV (one-four) chord vamp and associated single-note lines, as played in a variety of positions. Our vamp is in the key of E, built from the one chord, E7, moving to the four chord, A7, then resolving back to E7. In each instance, the two chords have been sounded in a specific position, followed by single-note licks based on the E blues scale (E G A Bb B D) as played in that same area.

Additionally, we’ve included the major third, G#, in order to allow greater melodic flexibility while also eliciting a stronger connection to the E7 chord by sounding each note of its arpeggio (E G# B D). The resulting hybrid scale is E G G# A B Bb D, which includes the chromatic row G G# A Bb B.
