About Adim9/F#
Adim9/F# is A Dim 9 with F# as the lowest note. This is the 3rd inversion of the chord — the same notes as A Dim 9 (A, C, D#, F#, B), but voiced so that F# sits in the bass. Slash chords create a smoother bass line movement and are common in chord progressions where the bass walks stepwise.
