About A#m7
A#m7 is built from four notes: A# (root), C# (minor third), E# (perfect fifth) and G# (minor seventh). Its interval formula is 1 – b3 – 5 – b7. The minor seventh softens the sadness of the minor chord and gives it a relaxed color, common in soul, funk and jazz.
On guitar, A#m7 has 3 common shapes: the A, E and D shapes. These are CAGED system shapes, the basis for playing the same chord anywhere on the neck.

The more common spelling is Bbm7.
