Understanding the Bb Suspended 2 chord
Names and symbols

Bb Suspended 2 and A# Suspended 2 are the same sound spelled two ways; both have a page here, and each links to the other. A# Suspended 2
How it is built
On Bb it is Bb · C · F: 1P · 2M · 5P. The third is gone, so the chord has no quality; the second sits in its place, a whole step above the root.
How it is used
Traditionally a suspension resolves — the second falls to the third. In modern pop and folk it very often does not, and the unresolved sound becomes the texture. Open-string guitar voicings fall into sus2 shapes almost by accident, which is much of why the sound is so associated with acoustic writing.
