What is the Ab7#11 Chord?
Learning the Ab7#11 chord tones gives you a set of notes to outline this harmony in bass lines and arpeggios. This chord is enharmonically equivalent to G#7#11.
Notes and Arpeggios
The 7#11 chord adds the Lydian #11 to a dominant 7th, combining dominant drive with Lydian brightness. It's a colorful altered tension that sounds sophisticated rather than dark — common in jazz and fusion for non-resolving dominants. The complete chord tones are: Ab, C, Eb, Gb, D. The complete formula is 1, 3, 5, b7, and #11.
How to Use It
You'll mostly hear altered dominants in jazz turnarounds and tense lead-in chords before a resolution. On bass, outline the harmony one note at a time. Start from the root and add the chord's actual degrees (3, 5, b7, and #11) as the arrangement allows. The chord-tone boxes locate notes; the ordered arpeggio gives a playable route with explicit position shifts.
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.
