B major augmented

The major augmented scale, also called ionian #5, is a major scale with a raised 5th: the third mode of the harmonic minor scale. One alteration turns the tonic triad augmented while every other degree stays diatonic, so familiar melodies acquire a lifted, unresolved center. It is the cleanest scale choice over maj7#5 chords.

it consists of these notes and degrees:

I+

C♯

ii

C♯m
D♯

III

A♯dim

Characteristic note: G (#5), the raised fifth that gives everything an augmented shimmer.

Same notes, different mode

B major 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.

major augmented in all 12 keys, with chords and related scales

tip
  • Play B major and raise only the 5th (G): the tonic triad turns augmented while every melody note stays familiar.
  • Use it over maj7#5 chords; as harmonic minor's third mode it shares fingerings with the harmonic minor a major 3rd above... borrow them.
  • Resolve #V (G) upward to VI or down to V mid-phrase; parking on it keeps the suspense, moving it tells a story.
  • Try a I to iii change in B: the augmented I chord against the minor iii creates the scale's signature lift.

How to play B major augmented on guitar

Open B doubles the root and both E strings give a perfect fourth, so tonic and fourth are on tap without fretting. Open G spells F## here. Roots run from fret 7 on the low E to fret 2 on the A, which means one barre position covers both. Capo fret 2 and A major augmented fingering takes over, so a key signature of five sharps stops mattering.
