A major 9 chord is a 5 note chord having a root, a major third, a perfect fifth, a major 7th and a major 9th.

The chord formula for a major 9 chord is 1 - 3 - 5 - 7 - 9

Stacking thirds: Major 3rd(3) - Minor 3rd(5) - Major 3rd(7) - Minor 3rd(9)


Example: Calculating a Gmaj9 chord
  • major 9th chords consist of the 1st, 3rd, 5th, 7th and 9th notes of the Major Scale
  • G chords are based on the scale of G major which consists of 1 sharp... F#. Because a 9th chord exceeds one octave (compound scale) we need to add an extra note to the existing one-octave scale (9 notes in total).
    The scale reads as follows: G - A - B - C - D - E - F# - G - A
  • Formula = 1, 3, 5, 7, 9
  • Substitute notes from the scale into the formula
  • The Gmaj9 chord chord = G - B - D - F# - A
