As an example, we take the C chord, and present examples for C major, minor and dominant variations. I’ve written below each note its appropriate degree of the C major scale. Major chords Variation 1: C6add9 = C E G A D Variation 2: Cmaj9add6 = C E G A B D Variation 1 is really a 6th chord. Note it has no 7th degree! Variation 2 is a rootless voicing (no root included). Minor Chords Cm11 = C F Bb Eb G I’ve omitted the 9th. Why? Because. Really no reason, just personal preference. Dominant Chords Variation 1: C9 = C E G Bb D Variation 2: C13 = C E G Bb D F A In the second variation I omitted the 11th degree (F). Again, just a matter of taste.
