Ab augmented heptatonic

The augmented heptatonic scale takes the symmetrical augmented scale and adds a perfect 4th, giving seven notes: root, sharp 2nd, major 3rd, 4th, 5th, sharp 5th, major 7th. The added 4th gives the symmetrical augmented sound a stepping stone toward conventional resolution. It suits maj7#5 harmony where you want both the exotic color and a smooth melodic line.

tip
  • Treat Ab augmented heptatonic as the augmented scale plus a perfect 4th: keep the shimmer, gain a stepping stone toward resolution.
  • Arpeggiate the two augmented triads inside it, then use the 4th (Db) as the pivot when you want the line to land.
  • Over maj7#5 harmony it offers everything the six-note augmented scale does, plus a suspension (IV to III).
  • The half-step pairs (#II-III, V-#V, VII-root) invite slides; the 4th is your one honest passing tone between them.

How to play A♭ augmented heptatonic on guitar

Nearest root is fret 1 on the G string, and both E strings answer at fret 4, which puts an E-shape barre at 4 in charge of this key. Capo fret 1 rewrites everything as G, which lets you borrow open-position moves and still play in Ab. Open G, B and both E strings are in the scale, though as a major seventh, augmented second and augmented fifth they work as passing tones, not a drone. Ebaug and Eaug hold the augmented pair.
