The B Locrian scale is the seventh and most unstable mode of the major scale. On Guitar, the notes are B, C, D, E, F, G, A. It sounds highly dissonant and unresolved, as its home chord is a diminished triad. While rare as a primary key, it is a crucial technical tool for jazz musicians improvising over half-diminished chords in tension-heavy passages. The diatonic chords of B Locrian are Bm7b5, CMaj7, Dm7, Em7, FMaj7, G7, Am7. Commonly used in Jazz, Metal, Experimental, Avant-Garde. Notable players include John Coltrane, Meshuggah, Dream Theater. Use over m7b5 (half-diminished) chords. Essential for jazz ii-V-i in minor keys where the ii chord is half-diminished.

About Drop B Tuning

Drop B tuning (B-F#-B-E-G#-C#) takes the guitar into territory traditionally reserved for 7-string instruments, delivering a subsonic heaviness that you can feel in your chest. This tuning has become essential in modern extreme metal, deathcore, and djent, where low-end clarity and rhythmic precision are paramount.

Drop B represents the practical limit of what a standard 6-string guitar can handle before tone quality degrades. With the right string gauge (12-60 or heavier) and proper setup, it delivers the crushing lows of a 7-string while keeping the familiar 6-string layout. Bands like Architects, Periphery (on some tracks), and Parkway Drive have used Drop B to create some of the heaviest riffs in modern metal.
