Locrian Mode
The unstable and dissonant mode - creating tension and uncertainty with its flat 2nd and flat 5th degrees.
Theory Fundamentals
Scale Properties
- •Formula: 1-♭2-♭3-4-♭5-♭6-♭7
- •Intervals: H-W-W-H-W-W-W
- •Key characteristics: ♭2 and ♭5 create instability
- •Character: Dissonant, unstable, mysterious
- •Function: Tension creation, avant-garde, metal
B Locrian Example
- •Notes: B-C-D-E-F-G-A-B
- •Parent scale: C major (starting on B)
- •Signature sound: ♭2 (C) and ♭5 (F) create tension
- •Perfect for: Metal, avant-garde, brief tension passages

Natural fingering with open strings:
Music Notation
Pattern Notes:
- • Root on 5th string, 2nd fret (B)
- • ♭2 interval (C) immediately above root
- • ♭5 interval (F) creates tritone instability
- • Difficult to establish as tonal center
F# Locrian - 2nd Position

Musical Applications
Metal Applications
Creating darkness and tension:
- • Brief passages over diminished chords
- • Chromatic approach tones
- • Dissonant harmony creation
- • Atmospheric intros and interludes
- • Progressive metal tension sections
Avant-Garde & Experimental
Modern classical and jazz applications:
- • Free jazz improvisation
- • Contemporary classical composition
- • Atonal melody creation
- • Sound design and texture
- • Experimental rock passages
Harmonic Context
Limited but powerful applications:
- • Over half-diminished chords (m7♭5)
- • Chromatic passing tones
- • Tension before resolution
- • Brief modal interchange
- • Leading into stable modes
