Fourth chords create harmonies reminiscent of McCoy Tyner’s playing. Stacked fourths have a wide open texture and are complimented very well by pentatonic scales. Begin on the third of a major scale and keep adding fourths as your taste dictates. Most voicings include a tritone as well as fourths. Fourth chords, similar to So What chords, can be moved around all scale degrees creating either new chords or variations on the root.
