Db 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 Db 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 (Gb) 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

Capo fret 1 and the whole key reads as C shapes, which means one fingering you already own covers it. Roots start at fret 9 of the low E. Open low E and A belong to the scale, but at an augmented second and augmented fifth above Db they read as passing tones rather than a drone. Abaug and Aaug both appear and no functional dominant sits under them, so nothing resolves unless you place the CMb5 yourself.
