G♯ / A♭ Locrian Scale

72 scales in every key on a map of the whole neck: positions, patterns, and every note played as it lights up.

The G♯ Locrian scale has 7 notes: G♯ – A – B – C♯ – D – E – F♯. Locrian is the darkest mode: a minor scale with a ♭2 and a ♭5, built on the 7th note of the major scale. Its root chord is diminished, so it is used for tension rather than as a home key.

G♯ and A♭ are the same pitch, so this page covers both names; the notes are spelled from G♯, the way the key is usually written. Compared with the G♯ major scale it has ♭2 (A instead of A♯), ♭3 (B instead of B♯), ♭5 (D instead of D♯), ♭6 (E instead of E♯), ♭7 (F♯ instead of F𝄪).

The explorer above is set to G♯ Locrian: the whole neck is mapped, and you can zoom into any of its 7 positions, change the labels to degrees or fingers, and hear it up, down and in patterns.
