7b5, DIAGRAM C major C major 9#11 and C major 13#11 chords IN FIVE SHAPES

The most important intervals in our three IV major chords are the root; the 3rd (which determines the quality of the chord); the 7th (which means any colour tone is then considered an extension); and the highest extension. However, in certain cases, we may have to omit the 7th degree with an ‘incomplete’ voicing that’s more symbolic of the full tonality. One example of this can be found on the C major 13#11 in shape 2, where, starting from the fourth string, there simply may not be enough available range for the full chord. On each diagram, the root notes are indicated in black, with the intervals that make up the specific voicing displayed within the notes.
