To play the A#m chord, perform a barre by pressing your index finger on the C-string, E-string, and bottom-A string on the 1st fret and ring finger on the 3rd fret of the top g-string.
The Bb minor chord, also known as an A#m, contains the notes Bb-Db-F.
To build a Bbm chord, take the minor triad formula (1-b3-5) and apply it to the Bb major scale (Bb, C, D, Eb, F, G, A).
Identify the first, third, and fifth scale degrees in a Bb major scale which are Bb-D-F.
Because the chord Bbm is a minor chord, lower the third scale degree a half step in accordance with the minor triad formula, which results in the notes Bb-Db-F for the Bb minor chord.
