A# Bebop in Drop B — Notes and Intervals
The A# Bebop scale is the dominant bebop scale, an eight-note extension of the Mixolydian mode. On Guitar, the notes are A#, C, D, D#, F, G, G#, A. By adding a chromatic passing tone, it ensures that the most important notes land on the strong beats, allowing jazz players to create fluid, professional-sounding lines. Commonly used in Jazz, Bebop, Swing, Hard Bop. Notable players include Charlie Parker, Wes Montgomery, Joe Pass, George Benson. Use over dominant 7th chords. The added passing tone ensures that the root, 3rd, 5th, and b7 fall on downbeats during eighth-note runs — the 'trick' that makes bebop sound professional.

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.
Notable artists: Architects, Parkway Drive, Whitechapel, Born of Osiris, Emmure
Best for: Extreme metal riffs, deathcore breakdowns, djent chugs, and any style demanding the lowest possible 6-string tuning
