Mandolin Fills With A# Aeolian
Where A# Aeolian lies on Mandolin's fretboard, and the fill it feeds.
A# Aeolian runs 7 notes to the octave. Below it is laid onto this chair's GDAE fretboard with every A# marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes under it.
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.
A mandolin fill is short and often tremolo-doubled, so the scale here is a source of two- and three-note runs between the vocal phrases, not a ladder to climb.
Play it slowly against the audio until the shape stops being a shape, then take it to a song in A# and let the melody pick its own notes out of it.
