C Augmented Scale
C Augmented contains 6 notes: C, E♭, E, G, A♭, B. It has 2 flats: E♭, A♭. The step pattern is W+H–H–W+H–H–W+H–H.
The augmented scale alternates minor 3rds and half steps across 6 notes. It interlocks two augmented triads a half step apart, creating a lush, ambiguous, Coltrane-esque sound.
The formula is 1, b3, 3, 5, #5, 7. Because the octave divides equally into major 3rds, only 4 distinct augmented scales exist. The alternation of minor 3rds (dark) and half steps (chromatic) creates a shimmering quality that is neither clearly major nor minor. It works over augmented chords and maj7#5 voicings, and provides a sophisticated alternative to whole-tone sonority.
Symmetrical patterns transpose by 4 frets (a major 3rd) and remain identical. This makes it efficient for navigating complex harmony. Practice superimposing the two augmented triads separately, then connect them chromatically.
