[Modes][Scales][Ionian][Aeolian][Dorian][Phrygian][Lydian][Mixolydian][Locrian][Summary]
The Locrian Mode originally ascended from B to B'. Not common in Western music, but much used in Eastern.
Reference:
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

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   G#   A#   C   C#   D#   F   G
