Whenever we dedicate time to internalizing musical material, it is ideal to choose structures that are applicable to many common jazz situations. This lesson focuses on one such structure that I have affectionately labelled the crunch chord. There are two main reasons this voicing is so versatile. First, it contains 2 tritones, so it can be used on 4 different dominant chords. Second, it contains many different smaller chords within its overarching structure. The relationships between these chords within the voicing create a unique harmonic texture that is useful for harmonizing any melody of your choosing.
