Guitar Fills With C# Lydian

C# Lydian runs 7 notes to the octave. Below it is laid onto this chair's EADGBE fretboard 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.

Major with a raised 4th (#4) — dreamy, ethereal, and floating. Often called the brightest mode, with an otherworldly suspended quality.

Heard in: Film scores, progressive rock, jazz — Joe Satriani's "Flying in a Blue Dream", John Williams, Steve Vai.

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