Structure
A# locrian scale notes:
How the locrian scale is built:
The locrian scale is built from the degrees 1 b2 b3 4 b5 b6 b7, which gives the step pattern H-W-W-H-W-W-W (W = whole step, H = half step).
Counting in semitones from the root: 0, 1, 3, 5, 6, 8, 10. That makes it a 7-note scale.
It is mode 7 of the Major Scale, so both scales share the same notes from a different starting point.
