About C9/A#

C9/A# is C Dom 9 with A# as the lowest note. This is the 3rd inversion of the chord — the same notes as C Dom 9 (C, E, G, A#, D), but voiced so that A# sits in the bass. Slash chords create a smoother bass line movement and are common in chord progressions where the bass walks stepwise.
