About the vi-IV-I-V progression
The vi-IV-I-V progression is a rotation of the classic four-chord pop pattern that starts on the relative minor. Because it opens on a minor chord and resolves upward, it feels darker and more emotionally weighted than starting on the tonic. It's a favorite of ballads and songs with a melancholic mood.
Playing in the key of Ab
Ab major is another all-barre key on guitar. Capo the 1st fret and use G-major shapes as an easier alternative.
