What's in F♯add9
An add9 chord is a major triad with the 9th added (the 2nd, an octave up) and no 7th: F♯add9 is F♯, A♯, C♯, G♯. Leaving out the 7th is what separates it from F♯9.
| Note | Formula | Interval from F♯ |
|---|---|---|
| F♯ | 1 | Root |
| A♯ | 3 | Major 3rd |
| C♯ | 5 | Perfect 5th |
| G♯ | 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.
