Bb Altered Scale: Fretboard Guide
The Bb Super Locrian scale consists of Bb, Cb, Db, Ebb, Fb, Gb and Ab. Ebb is the only double flat, and it sounds like D, the major third of a Bb dominant chord.
Place the root on the 6th fret of the low E string or the 1st fret of the A string. Cb melodic minor is its parent, and the A# page spells the same notes with sharps.

Structure
Bb super locrian scale notes:
How the super locrian scale is built:
The super locrian scale is built from the degrees 1 b2 b3 b4 b5 b6 b7, which gives the step pattern H-W-H-W-W-W-W (W = whole step, H = half step).
Counting in semitones from the root: 0, 1, 3, 4, 6, 8, 10. That makes it a 7-note scale.
It is mode 7 of the Melodic Minor Scale, so both scales share the same notes from a different starting point.
It is also known as Altered Scale and Altered Dominant.
