About Bbsus2
The Bbsus2 chord is made up of Bb (root), C (second) and F (perfect fifth). In scale degrees above the root, the formula is 1 – 2 – 5. With no third it leaves the harmony undefined: it sounds open and modern, and it is used a lot in pop and rock.
Bbsus2 has no standard open shape in the CAGED system, so its 20 voicings are sorted only by difficulty and position on the neck. Bbsus2 is also written as A#sus2: the same chord with the root spelled differently, and it sounds identical. The more common spelling is Bbsus2.
