Bb 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:

B♭

I

C♯

#II

D

III

F

V

#V

A

VII

Same notes, different mode

Bb 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 Bb augmented scale interlocks two augmented triads: arpeggiate them separately (root, III, #V (F#) and #II (C#), V, VII) to see its skeleton.
  • Use it over maj7#5 chords; the major 7th (A) and raised 5th (F#) 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 (C#) to III, V to #V (F#), VII to root) for lines that shimmer without sounding chromatic.

How to play B♭ augmented on guitar

Roots gather low: the 6th fret on both E strings, the 1st on the A string, the 3rd on the G. A capo at the 1st fret turns this into A augmented, so low-position shapes you already play cover it. Open A stands a major seventh over the root, with open D a major third, which means neither belongs under a drone. Box work carries to fret 10.
