Gb augmented

The augmented scale is a six note symmetrical scale alternating minor 3rd and half step: root, sharp 2nd, major 3rd, 5th, sharp 5th, major 7th. It interlocks two augmented triads a half step apart, repeating its pattern every major 3rd. Jazz players run it over maj7#5 chords; its symmetry means one fingering transposes around the neck in major-3rd jumps.

it consists of these notes and degrees:

I

#II

B♭

III

V

Same notes, different mode

Gb augmented uses the same notes as the scales below. Start from a different note and you get a new mode built on the very same note set.

tip
  • The Gb augmented scale interlocks two augmented triads: arpeggiate them separately (root, III, #V (D) and #II (A), V, VII) to see its skeleton.
  • Use it over maj7#5 chords; the major 7th (F) and raised 5th (D) are both scale tones, which almost no other scale offers.
  • Its symmetry repeats every major 3rd (four frets), so one fingering transposes twice before it recurs at the octave.
  • Slide between the half-step pairs (#II (A) to III, V to #V (D), VII to root) for lines that shimmer without sounding chromatic.

How to play G♭ augmented on guitar

A capo on fret 2 rewrites this key as E augmented, so shapes you own down there transfer up whole. Roots without a capo land at fret 2 on both E strings, fret 9 on the A string and fret 4 on the D. Open A runs an augmented second over the root and open D an augmented fifth, which means the open strings stay out of it. First box gives out at fret 6.
