Bb Dorian b2: Fretboard Guide
The Bb Dorian b2 scale runs Bb, Cb, Db, Eb, F, G and Ab. Cb is a B in disguise, which is the only spelling quirk.
Bb sits on the 6th fret of the low E string and the 1st fret of the A string, an easy spot for the A-string shapes. Jazz players meet this mode as the second mode of melodic minor, and bebop scales add more jazz vocabulary.

Structure
Bb dorian b2 scale notes:
How the dorian b2 scale is built:
The dorian b2 scale is built from the degrees 1 b2 b3 4 5 6 b7, which gives the step pattern H-W-W-W-W-H-W (W = whole step, H = half step).
Counting in semitones from the root: 0, 1, 3, 5, 7, 9, 10. That makes it a 7-note scale.
It is mode 2 of the Melodic Minor Scale, so both scales share the same notes from a different starting point.
It is also known as Phrygian #6.
