Bb 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 Bb 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 (Eb) 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 B♭ augmented heptatonic on guitar

Only the open A and D strings belong here, so drones are thin and the work is fretted. Fret 1 on the A string carries the root, which puts the A-shape barre right at the nut end and the E-shape at 6. Capo fret 1 turns it into A shapes. Faug and F#aug both appear, so the V+ gives you two augmented options and no pull back to BbM.
