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
