A Lydian on Guitar

A Lydian runs 7 notes to the octave. Below it is mapped onto this instrument's E–A–D–G–B–E fretboard with every A marked, because what a player needs mid-number is not the pattern but where the root is when the harmony moves 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.

Scale work in the armonía is for the passing figure that joins one chord to the next — a few notes at the seam of a change, played by one member while the other keeps the pattern intact.

Take it slowly against the playback until the geometry stops being geometry, then put it under a number in A and let the written line pick its own notes out of it.
