Perfect by Ed Sheeran is played in the key of G at a beginner difficulty level, originally released in the 2010s. It uses 4 chords — G Em C D — arranged in the I-vi-IV-V progression.
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 G
G major is one of the easiest keys on guitar. Its primary chords — G, C, and D — are all open first-position shapes, and the relative minor (Em) is one of the simplest grips on the instrument. A great key to spend time in as a beginner.
