Aaug: guitar chord voicings, inversions, scales and arpeggios

Aaug (Augmented) is an interactive GuitarArcanum page with chord formula, intervals, voicings, inversions, triads, pentatonic patterns, scales and arpeggios on the fretboard.

Chord formula

Interval formula: 1 3 #5. An augmented triad — root, major 3rd and sharp 5th. A symmetric, hanging chord with no clear rest.

Chord tones

The sharp 5th splits the octave into equal major thirds. Because it's symmetric, the chord has no clear center and pulls upward.

Sound character

Mysterious, lifted and unstable — a whole-tone, floating color.

Harmonic function

Most often a dominant with a raised 5th, or a passing chord pulling upward.

Typical progressions

A – Aaug – D
E+ → C
I – I+ – IV

Guitar voicing advice

Compact shapes from the 5th and 4th strings. Because it's symmetric, one shape repeats every four frets.
