About the I-vi-IV-V progression
The I-vi-IV-V progression is the classic 1950s "doo-wop" pattern. From home, it moves to the relative minor, then through the subdominant to the dominant, creating a gentle rocking-chair feel that defined early rock and roll harmony. Countless doo-wop, oldies, and pop ballads use this shape.
Playing in the key of Eb
Eb major uses Eb, Ab, and Bb — all barre chords. Capo the 3rd fret and use C-major shapes to make this key approachable.
