About C/F
C/F gives the bass its own instruction: keep the upper chord, but make the lowest note. The slash separates those two jobs.
F is not in the upper triad; it puts the upper chord’s fourth in the lowest voice. Hold the upper chord steady and move only the bass. That low line can connect nearby chords without jumping root to root.
Also written C over F or C with F in the bass.
How to use C/F
In which keys. Every note of C/F belongs to C major (the I, the tonic), D minor (the ♭VII), F major (the V, the dominant) and A minor (the ♭III).
