The A#m9 chord (A# minor ninth) is spelled A#, C#, E#, G# and B#. It sounds identical to Bbm9, which uses Bb, Db, F, Ab and C. Both names describe the same five pitches, so only the spelling differs.
The sharp spelling needs both E# and B#, which are the same pitches as F and C. Three voicings are listed, one of them a barre shape, and the lowest begins at the 4th fret. The A# Dorian scale contains all five notes.
The fretboard at the top labels every note of each shape, including the E# and the B#.
A# minor 9th guitar chord is also written as A#m9, A#min9 or A#-9.
