How to use the G♭maj9 chord

The G♭maj9 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 G♭maj9 differs from similar chords

G♭maj9 stacks a major ninth on G♭maj7, and it differs from G♭9 only in the seventh, a half step higher. Without that major seventh it would be G♭add9. Its upper four notes form the minor seventh chord a major third above the root, which is how pianists often voice it.
