What is the A Locrian Scale?

The Locrian mode is the darkest and most unstable of all modes, featuring both a flat 2nd and a flat 5th. This creates a diminished, unresolved quality that makes it challenging to use but powerful for creating extreme tension.

Interval Pattern: H-W-W-H-W-W-W

Playing Tips

Use sparingly for maximum impact. The diminished 5th makes traditional resolution impossible. Works over half-diminished chords. Great for creating tension before resolving to another mode.
