Locrian Mode

The Locrian Mode originally ascended from B to B'. Not common in Western music, but much used in Eastern.

Reference Scale:

  1 2 3 4 5 6 7 8 9 10 11 12 1'
Note C C# D D# E F F# G G# A A# B C
Note C Db D Eb E F Gb G Ab A Bb B C

Use this table to construct the mode starting on any note, using the pattern of intervals below.

Locrian Mode:


  I   II   III   IV   V   VI   VII   VIII
    Semitone   Tone   Tone   Semitone   Tone   Tone   Tone  
Note B   C   D   E   F   G   A   B

This pattern of intervals: S-T-T-S-T-T-T* is the characteristic of the Locrian mode. Because the mode is characterised by its interval structure, you can start on any note and progress with the same intervals to produce a Locrian mode in that 'key'.

This would be 'G Locrian':

  I   II   III   IV   V   VI   VII   VIII
    Semitone   Tone   Tone   Semitone   Tone   Tone   Tone  
Note G   Ab(G#)   Bb(A#)   C   Db(C#)   Eb(D#)   F   G

* T = Whole Tone, S = Semitone
