The CMaj9(add13) chord makes it possible to play the 13th without having the sharp 11th, and this is most commonly used as the 11th can often clash with other parts! To indicate this, we can say:
- Cmaj7(add 13)
- Cmaj9(add 13)
By saying ‘add,’ we’re told not to play the sharp 11th.
The CMaj9(add13) chord (also known as CMaj9(13), C Major 9 (add13) and C△9(add13)), has a distinctive and unique tone.
