C 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 C 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 (F) 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 C augmented heptatonic on guitar

Open low E, G and B all belong to this key, and the high E doubles that major third, so a drone under the melody costs you nothing. Lowest root waits at fret 8 of the low E, with another three frets from the nut on the A string. Gaug and G#aug both live here. Two augmented triads and no functional dominant means V+ never pulls home, which lets you hold Gaug as color rather than a turnaround.
