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 chord tones are: C#, E#, G#, B#, D#. It's built from degrees 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, you usually outline this chord instead of strumming it: emphasize the root, 3rd, 5th, and 7th as the harmony requires, then use passing tones to connect back to the groove.

Play root and 5th on strong beats, then add the 3rd or 7th to make the chord quality clear. Use the highlights to spot where the same tone repeats across strings.
