What's in Dadd9
An add9 chord is a major triad with the 9th added (the 2nd, an octave up) and no 7th: Dadd9 is D, F♯, A, E. Leaving out the 7th is what separates it from D9.
| Note | Formula | Interval from D |
|---|---|---|
| D | 1 | Root |
| F♯ | 3 | Major 3rd |
| A | 5 | Perfect 5th |
| E | 9 | Major 9th |
Brighter than a plain major chord, with a bit of shimmer from the 9th. Acoustic players lean on it because add9 shapes often keep fingers anchored between changes: Cadd9 played x32033 shares its top two notes, D and G, with the G shape 320033.
