B 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 B Locrian scale has 7 notes: B – C – D – E – F – G – A. 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.

Compared with the B major scale it has ♭2 (C instead of C♯), ♭3 (D instead of D♯), ♭5 (F instead of F♯), ♭6 (G instead of G♯), ♭7 (A instead of A♯).

The explorer above is set to B 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.

How to practise it

Play position 1 (frets 7–12) slowly, up and down, saying the note names.
Play it with the pattern set to In 3s, then In 4s, at a tempo where every note is clean.
Learn position 2 and how it joins position 1: the notes they share are where your hand moves.
Switch the labels to degrees and find every B (1) in each position.
Improvise over a backing track, ending your phrases on B.
