C6 Pedal Steel Fills With F Whole Half Diminished

F Whole Half Diminished runs 8 notes to the octave. Below it is laid onto this chair's C6 neck with every F marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes under it.

Unstable and eerie — alternating whole and half steps, with the b3, b5, and 6 spelling a diminished seventh chord in every direction. Ominous, symmetrical, and unresolved.

Heard in: Diminished seventh chords in classical and jazz, horror and suspense scores, Bartok and Stravinsky, and neoclassical metal.

A pedal steel fill is a line the bar and the pedals share: the bar comes to rest on a fret, and a pedal or lever raises a ringing string into the next note of the line, so a scale here marks the resting places and the notes a bend can reach from them.

Play it slowly against the audio until the shape stops being a shape, then take it to a song in F and let the melody pick its own notes out of it.
