Theory behind the chord
Diminished seventh chords divide the octave into four equal minor thirds. Every inversion sounds the same, so a single shape can be slid up the neck to lead into several different keys. On Fdim7 this structure sits on the root F, so the degrees 1 – ♭3 – ♭5 – ♭♭7 map onto F, G#, B and D.
