Musical Analysis

Notably, the primary chords in the progression (G and C) are not part of the A major scale. “Penny Lane” is characteristically Beatles-esque in its use of unexpected chord movements and key changes, which add intrigue to the piece without making it sound disjointed or random. The use of the V/vi (E7) chord as a pivot to transition between key areas is very nicely done and is an excellent example of the Beatles’ clever songwriting.

Overall Analysis

“Penny Lane,” written by the Beatles, utilizes key changes and borrowed chords to create an interesting and complex tonal palette. The song is best understood to primarily be in the key of A Major; however, it frequently borrows chords from the parallel minor key, uses unexpected dominant chords, and briefly modulates to other key areas for color and variety. This is characteristic of several Beatles songs, and it’s one of the ways they added complexity to their music while still remaining accessible.

“Penny Lane” is characterized stylistically by its lush arrangements, complex harmonies, and stylistic mixture of traditional ‘pop’ songwriting, classical influence (particularly Baroque), and modern recording techniques. The section of the chorus analyzed here exemplifies this, with the borrowed chords adding unexpected color to the progression and the E7 resolving back to the home key in a satisfying manner.
