Ab lydian augmented dominant

It matches 7#5#11 chords note for note, sitting one step further out than lydian dominant. Fusion players use it when a dominant chord should glow rather than resolve.

tip
  • Over a 7#5#11 chord, every note of Ab lydian augmented dominant lands; arpeggiate III, #IV (D), #V (E), bVII (Gb) to spell the chord's color.
  • Resolve it as a dominant: bVII (Gb) falls to the 3rd of the chord a 4th above Ab, and the raised tones settle by half step.
  • One notch brighter than lydian dominant: swap between the two over a vamp by moving only the 5th.
  • It is the third mode of neapolitan major; recycle that scale's fingering from a major 6th below.

How to play A♭ lydian augmented dominant on guitar

Both E strings and the open D fall in this key as an augmented fifth and an augmented fourth over the root, so three strings ring even though none of them drones cleanly. G string fret 1 is the nearest root to the nut, which lets you start low without any barre. Fret 4 on both E strings and fret 9 on the B carry the rest. Capo fret 1 and it reads as G, so G fingerings transfer directly. Fret 8 caps the first box.
