See Mentorship PlansThe A# Locrian scale has 7 notes: A# B C# D# E F# G#. Its formula is 1 b2 b3 4 b5 b6 b7, and the gaps between the notes go H W W H W W W (W is a whole step of two frets, H is a half step of one fret). A# Locrian uses the same notes as B major, its parent major scale. The difference is that everything centres on A#.
Compared with A# minor, it has the flat 2nd (B) and the flat 5th (E) instead of the 2nd (B#) and the 5th (E#).
| Degree | Interval | Name | Note |
|---|---|---|---|
| 1 | 1 | Root | A♯ |
| 2 | b2 | Flat 2nd | B |
| 3 | b3 | Minor 3rd | C♯ |
| 4 | 4 | 4th | D♯ |
| 5 | b5 | Flat 5th | E |
| 6 | b6 | Minor 6th | F♯ |
| 7 | b7 | Minor 7th | G♯ |
The fretboard above shows A# Locrian across all 24 frets. Its root, A#, is on the low E string at the 6th fret, and Position 1 starts there. Use the Shape menu to see the 5 positions one at a time (plus the seven 3-notes-per-string shapes, great for speed and legato), press Play to hear the one you're looking at, and switch the labels to intervals to see where the root, 3rd and 5th sit in each shape.
Learn one position until you can play it up and down without looking, then learn the next one along and practise moving between the two. Before long the whole neck joins up.
These are the chords you get by stacking every other note of the scale on each degree. They're the chords that sound "at home" with A# Locrian.

Locrian is the darkest of the modes, with both a flat 2nd and a flat 5th. It's rarely used as a key, but it's exactly the right sound for half-diminished chords.
Use it over A#m7b5 chords, for example the ii chord in a minor ii V i. In metal it's also used for heavy, unsettling riffs.
