Decoding the D9 Chord: Notes and Formula
The D9 chord is composed of five distinct notes:
- D – Root (1)
- F# – Major Third (3)
- A – Perfect Fifth (5)
- C – Minor Seventh (b7)
- E – Major Ninth (9)
These notes are derived from the Dominant Ninth chord formula, which outlines the specific intervals from the root note that create this chord type.
Dominant Ninth Chord Formula:
| Interval | Degree |
|---|---|
| Root | 1 |
| Major Second | 9 |
| Major Third | 3 |
| Perfect Fourth | 11 |
| Perfect Fifth | 5 |
| Major Sixth | 13 |
| Minor Seventh | b7 |
| Major Seventh | 7 |
In the context of the D9 chord, we select the 1st, 3rd, 5th, b7th, and 9th intervals from the D major scale to construct its unique sound. This formula is consistent across all dominant ninth chords, simply changing the root note.
