About Cdim9/A
Cdim9/A is C Dim 9 with A as the lowest note. This is the 3rd inversion of the chord — the same notes as C Dim 9 (C, D#, F#, 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.
