What is the G Major 9 Chord?
Here's a fretboard view of the G Major 9 chord so you can see where each chord tone lives across the neck.
Notes and Arpeggios
Major 9th chords extend the major 7th by adding the 9th, creating a lush, sophisticated voicing that's a hallmark of neo-soul, R&B ballads, and jazz. They sound rich and full without any of the tension found in dominant chords. The complete chord tones are: G, B, D, F#, A. The complete formula is 1, 3, 5, 7, and 9.
How to Use It
Extended voicings are a staple of jazz, neo-soul, and modern pop harmony. On bass, outline the harmony one note at a time. Start from the root and add the chord's actual degrees (3, 5, 7, and 9) as the arrangement allows. The chord-tone boxes locate notes; the ordered arpeggio gives a playable route with explicit position shifts.
Connect this chord to the next harmony using nearby chord tones. Shift the hand when the line needs it rather than stretching beyond a comfortable position. Use the highlights to spot where the same tone repeats across strings.
