Guitar Fills With F Mixolydian

F Mixolydian runs 7 notes to the octave. Below it is laid onto this chair's EADGBE fretboard 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.

Major with a flatted 7th (b7) — bright and bluesy. The dominant chord turned into a tonal center with a rock/folk edge.

Heard in: "Sweet Home Chicago", "Norwegian Wood" (Beatles), Celtic and folk music — anywhere a major sound needs a darker, looser edge.

A guitar fill is a flatpicked line, and it lives closest to the vocal melody of any chair in the arrangement — the scale is what fills the bar where the melody is only a long note.

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.
