A 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 A 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 (D) 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

Open A string is the root, with both E strings a fifth away and open D a fourth, so four strings ring the key untouched. Fretted roots follow at fret 5 on the low E and fret 2 on the G, which means first-position work and the E-shape barre at 5 share the same region. Dm takes the iv. Eaug and E#aug are the augmented triads, and without a functional dominant nothing here resolves on its own.
