ExAMPLE 2 octave melody
Like numerous other jazz guitarists (most notably Wes Montgomery), Ronny uses octaves to beef up his playing - the lower octave adding body to the upper octave. It also encourages you to be more melodic and less ‘box’ based with your phrasing. Notice how the syncopated D Dorian melody (D E F G A B C) is rounded off in bar 4 with chord voicings in 4ths. You can hear Ronny using these types of chords on tracks like So What, which up the sophistication quota without confusing the underlying harmony. If you like this type of chordal approach you could do a lot worse than checking out the jazz pianist, McCoy Tyner.
