C 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 C Locrian scale has 7 notes: C – D♭ – E♭ – F – G♭ – A♭ – B♭. 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 C major scale it has ♭2 (D♭ instead of D), ♭3 (E♭ instead of E), ♭5 (G♭ instead of G), ♭6 (A♭ instead of A), ♭7 (B♭ instead of B).

The explorer above is set to C 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 8–13) 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 C (1) in each position.
Improvise over a backing track, ending your phrases on C.
