Locrian Mode

The Locrian Mode is one of the seven modes. The B Locrian has the same notes as in C Major, but the tonic starts at B. Compared to the Major scale, all notes except the tonic and 4th degree are flattened. This creates a diminished character and gives the Locrian Scale an unstable sound.

The chords built from the tonic is diminished, such as Bdim that includes the notes B, D and F. An especially common choice is to use this scale over half-diminished chords and it is probably most used in jazz. See also Super Locrian Scale.

Relative keys – Locrian and Major

The same notes can be found in different Major and Locrian scales:

It is only a semi-step between the roots in the relative scales. One way to approach this relationship is to view B Locrian as C Major starting from its 7th degree.

The ancient heritage

The Locrian Scale emerged in the ancient Greece together with other scales such as Aeolian and Dorian. The names were taken from regions or people – the Locrians once lived in Central Greece.

Altered Locrian #2 and b4

Two relevant scales are the Altered Locrian #2 (sharp two) and the Altered Locrian b4 (flat four), also known as the Super Locrian. These are identical to the Locrian except for the raised second and flattened fourth.
