Notes and Arpeggios

Major 7th chords add the natural 7th to a major triad, producing a smooth, lush sound often described as "jazzy" or sophisticated. They feel stable but colorful — a step up from a basic major chord without adding tension. The chord tones are: Ab, C, Eb, G. It's built from degrees 1, 3, 5, and 7.

How to Use It

This is especially common in blues and jazz, and it also shows up in funk and R&B comping. 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.
