E9 Pedal Steel Fills With C# Mixolydian Bebop

C# Mixolydian Bebop runs 8 notes to the octave. Below it is laid onto this chair's E9 neck with every C# marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes under it.

Mixolydian with a passing major 7th between the b7 and the octave — the bright, bluesy dominant sound with a chromatic slide that keeps every chord tone on a downbeat. Slick, swinging, and quintessentially bebop.

Heard in: Jazz lines over dominant seventh chords, blues changes, and rhythm changes — the workhorse bebop scale.

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 C# and let the melody pick its own notes out of it.
