B lydian augmented

The lydian augmented scale, the third mode of the melodic minor scale, raises both the 4th and 5th of a major scale. It outlines a maj7#5 chord with a #11, about the brightest and least grounded color mainstream jazz harmony uses. Reach for it when a major 7th chord should shimmer instead of rest.

it consists of these notes and degrees:

B

I+

Baug
C♯

II

C♯maj
D♯

III

D♯maj
E♯

#iv°

E♯dim
F𝄪

#v°

F𝄪dim
G♯

vi

G♯m
A♯

vii

A♯m

Characteristic notes: F (#4) and G (#5), the raised fourth and fifth floating over a melodic minor base.

Same notes, different mode

B lydian 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
  • Play it over maj7#5 chords: B lydian augmented is the only common scale containing both the #4 (F) and #5 (G) above a major 7th frame.
  • Suspend rather than resolve: hold #IV (F) or #V (G) over the chord and let the brightness hang.
  • Think melodic minor down a minor 3rd from B; the fingering transfers directly.
  • Use it for a two-chord lift: Bmaj7#5 moving to the plain maj7 a whole step down turns the scale into an arrival effect.

How to play B lydian augmented on guitar

Open B is the root here, and the open G string spells F##, the augmented fifth, so two open strings cover root and altered fifth together. Baug covers I+, so those two open notes are two thirds of the home triad. Fretted roots sit at 7 on both E strings, 2 on the A and 9 on the D. Six sharps, plus one double sharp. Position one ends at fret 11, so the 7th-fret box carries the low neck.
