“Penny Lane” by The Beatles is a pop rock song released in 1967. Musically, the track displays characteristics of the “Baroque pop” style combine with psychedelic pop. The composition is multifaceted with complex chord progressions inspired by classical music, as well as elements of the British music hall style, specifically brass band influences throughout.

“Let It Be” by The Beatles utilizes a very accessible and effective chord progression throughout the song. This progression is designed to create tension and release as it progresses, as well as establish the root key of the song, which is C Major.

The chords used throughout the song show a strong use of borrowed chords, inversions, and extensions, adding to the depth and complexity of the song despite the relatively uncomplicated chord progression.

The balance between the root key, dissonance, resolution, and overall harmony creates an emotive and engaging song that maintains listener interest and displays the songwriting abilities of The Beatles.

The chorus of “Closer” by Nine Inch Nails is built around a progression that oscillates between a single major chord, F, and a single minor seventh chord, Cm7. This is quite minimalistic. Major chords usually have a happy, positive feel, while minor chords induce a somewhat sad, introspective mood. The use of C minor 7th gives a particular color to the progression: it’s a minor chord with an added minor seventh, which means it’s a bit less stable than a regular minor chord.

“For No One” is a song from The Beatles’ album Revolver, released in 1966. The song has a melancholic theme, represented quite well through a sophisticated chord progression that features significant use of the minor scale and infrequent use of chord extensions, such as 7th and suspended chords. It’s written primarily in C Major, but the chorus alternates between D Minor and A7, an interesting modal shift (Using structural chords from different modes).

“Boulevard of Broken Dreams” by Green Day, released in 2004, is an alt-rock anthem that largely follows a 4-chord progression throughout the song. The key signature of the song is E minor (derived from the root chord), and essentially all chords used in the song are diatonic, meaning they are derived from the scales of the key. The chorus shifts to a progression in C Major. However, it returns to E minor at the end.

“`
G Major: bVII
B Minor: ii
C Major: bIII
G Major: bVII
B Minor: ii
C Major: bIII
G Major: bVII
B Minor: ii
C Major: bIII

“`
The above chords contains borrowed chords which are chords borrowed from the parallel minor key, In the key of A major, the parallel minor is A minor. So, the G and C chords are borrowed from A minor.

Here’s the line with borrowed chords written in code block:

“`G Major (bVII), C Major (bIII)“`

Similar Chord Progressions

The Beatles’ use of borrowed chords and key changes was influential and can be seen in many songs by other artists. For example, the Beach Boys’ “God Only Knows” uses similar techniques. In particular, “Uncle Albert/Admiral Halsey” by Paul McCartney also utilizes a similar style of chord borrowing and modulations.

Chord progression in these songs:

“God Only Knows” by The Beach Boys:

“`C (I), E7 (V/vi), F (IV), D (bII)“`

“Uncle Albert/Admiral Halsey” by Paul McCartney:

“`G (I), E7(V/vi), A7 (dominant V)“`

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.

Style Analysis

“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.
