How to use the Gmaj9 chord
The Gmaj9 chord is built from a root, a major third, a perfect fifth, a major seventh and a major ninth. Start at the root G and stack the intervals to get the whole chord: G, B, D, F♯ and A. The same formula gives you the chord in any other key.
Major ninth chords work as the I or IV chord where a major seventh would do, adding depth without changing the function. Bossa nova, jazz, soul and R&B treat them as a default tonic sound.
How Gmaj9 differs from similar chords
Gmaj9 stacks a major ninth on Gmaj7, and it differs from G9 only in the seventh, a half step higher. Without that major seventh it would be Gadd9. Its upper four notes form the minor seventh chord a major third above the root, which is how pianists often voice it.
Where Gmaj9 is used
A major chord is at home as a tonic, and just as useful as the IV or the V of a neighbouring key. Each progression below is written in the key its numerals name.
