D 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.

it consists of these notes and degrees:

tip
  • Treat D 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 (G) 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 D augmented heptatonic on guitar

Open D string is the root itself, with open A a perfect fifth and open G a perfect fourth under it, so a three-string drone needs no left hand at all. Fretted roots pick up at fret 5 on the A string and fret 10 on both E strings. Aaug and A#aug stack the two augmented triads next to each other, which lets you shift one shape instead of learning two. Gm fills the iv slot.
