Piano: Ab Aeolian Over the Changes
Where Ab Aeolian lies at this seat, and what a chorus takes out of it.
Ab Aeolian runs 7 notes to the octave, laid out here across 88 keys with every Ab flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.
The standard natural minor scale — melancholic, introspective, and deeply emotive. The most common minor sound in Western music.
Heard in: Pop, rock, classical, metal — the default minor sound of Western music.
The right hand takes the line and the left keeps stating the chord under it, which makes a scale at this seat a two-handed problem: the notes have to work against a voicing you are choosing at the same time.
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.
