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: Bb, D, F, A, C. 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.

Build a one-bar bass line from the chord tones before adding scale passing tones. Use the highlights to spot where the same tone repeats across strings.
