What are extended chords used for?
Extended chords are generally used when a richer harmonic “color” is desired. Since 9th chords are among the most popular extended chords, let's begin with them. If you were to take a Cmaj7 chord (C-E-G-B) and add a D note to the voicing, you would be creating a Cmaj9 (R[oot]-3–5-7-9; C-E-G-B-D).
