About C7b5/F#
C7b5/F# is C 7 b5 with F# as the lowest note. This is the 2nd inversion of the chord — the same notes as C 7 b5 (C, E, F#, A#), 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.
