Guitar: A Lydian Over the Changes

Where A Lydian lies at this seat, and what a chorus takes out of it.

A Lydian runs 7 notes to the octave, laid out here on EADGBE with every A flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.

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 chorus is a single line with the comp dropped, so a scale here is what the picking hand walks through between the two or three phrases it actually meant to play.

Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
