Augmented major seventh chords are a sophisticated harmonic element in jazz guitar. They add a unique color and tension to your improvisations and comping. Mastering these chords can elevate your playing and expand your harmonic vocabulary.
Understanding Augmented Major Seventh Chords
An augmented major seventh chord is built by stacking a root, a major third, an augmented fifth, and a major seventh. Its formula is 1 – 3 – #5 – 7. This chord has a distinctive, shimmering sound that combines the brightness of the augmented fifth with the stability of the major seventh.
Voicing Tips for Jazz Guitar
When voicing augmented major seventh chords on guitar, consider these tips:
- Use open strings to create rich, resonant sounds.

Common Voicing Ideas
Here are some practical voicing ideas for augmented major seventh chords:
- Root position: Play the chord with the root on the 6th string, with the other notes on higher strings.
- First inversion: Use the major seventh in the bass, with the augmented fifth and major third above.
- Drop 2 voicing: Drop the second highest note of a closed voicing down an octave for a more spread sound.

To incorporate augmented major seventh chords into your playing:
- Practice voicings slowly, focusing on clean tone and accurate intonation.
