The Bebop Locrian scale is a fusion of bebop jazz tones with the dark, mysterious sounds of the Locrian mode. It's an eight-note scale that introduces chromaticism, a defining feature of bebop, inside the more unsettling confines of the Locrian's diminished framework. This scale extends the traditional seven-note Locrian scale by adding an extra note, usually a major 7th (leading tone), which enhances the smooth, flowing, and often slippery characteristics desired in bebop improvisation. Guitarists will find the Bebop Locrian particularly flexible for soloing over dominant b9 chords or when exploring minor key jazz tunes requiring a modern, avant-garde touch. Understanding its structure can substantially enrich a player's ability to craft intricate and swinging improvisational lines.
