Guitar: Ab Ionian Over the Changes
Where Ab Ionian lies at this seat, and what a chorus takes out of it.
Ab Ionian runs 7 notes to the octave, laid out here on EADGBE with every Ab flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.
Bright, resolved, and stable. The foundation of Western tonal music and the most common mode in pop, classical, folk, and jazz.
Heard in: Pop, classical, country, folk, gospel — the default major tonality of Western music.
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.
