The song “Eight Days a Week” by The Beatles is an interesting example of pop music songwriting from the mid 1960’s. It showcases Paul McCartney and John Lennon’s ability to use common chord progressions and tweak them in a unique and recognizable way. It utilizes a simple progression in the verse but what makes it different is their use of 7th and borrowed chords. The key of the song is D major.

“Stairway to Heaven” is a progressive rock song by Led Zeppelin, released in 1971. The song showcases a movement between different styles and musical settings, as it starts with a gentle, fingerpicked acoustic section and gradually evolves into a powerful and climactic electric guitar solo, finishing with a full-band finale. The song is characterized by its ascending progression and intricate chord changes, which contribute to its unique and haunting atmosphere. The verse 1 chord progression features a blend of diatonic and chromatic elements, borrowed chords, and inversions, which create a sense of tension and resolution throughout the progression.

The song “Purple Rain” by Prince is a classic and showcases some interesting use of chord progressions. The key of the song is G major. The classic, popular music formula is present in the use of common chords like I, ii, IV, V which are all diatonic within the key. Noticeably, this song opts for a more simplistic, cyclical chord progression structure that emphasizes repetition of strong melodic lines.

This iconic Britpop song predominantly features the use of traditional tonal harmony found in pop songs throughout the late 20th century, and the verse specifically recalls the harmonic patterns utilized in the 1950s and 60s. The defining feature of this song (as is the case with many Oasis tunes) is the use of returning, resounding repetitions of simple chord sequences.

Similar Chord Progressions

One common progression that shares some similarities with “I Will” is the progression used in “Earth Angel” by The Penguins:

‘Eb (I)’, ‘Bb/D (V/iii)’, ‘Cm7 (ii7)’, ‘F7 (V7)’, ‘Bb (IV)’, ‘Eb (I)’, ‘Bb/D (V/iii)’, ‘Ab (bVII)’, ‘Eb (I)’

The key difference here is a bVII (Ab) chord, which acts as a borrowed chord from the key of Eb minor. It sidesteps the expected V chord and leads back to the I chord for the next repetition of the progression. This chord, similar to the borrowed chords in ‘I Will’, gives the progression an added color and complexity.

Musical Analysis

The underlying structure of ‘I Will’ showcases an interesting use of several common progressions and cadences within the key of C major. The use of a I-vi-ii-V cycle provides a strong forward momentum to the progression, propelling it towards the repetition. The I7 (C7) chord is a secondary dominant, specifically a V/IV that serves as a pivot chord to introduce the IV (F) chord. This adds an unexpected twist that enhances the harmonic interest of the song.

Overall Analysis

The song “I Will” by The Beatles is an example of their unique and sophisticated approach to pop songwriting, demonstrating their comprehensive mastery of harmony within the pop idiom. The majority of the harmonies used in the song are diatonic to the key of C major, however there are several instances of borrowed chords that add color and complexity to the song’s overall harmonic structure.

Style Analysis

The Beatles’ “I Will” is marked by its simplicity and economy. Its chord progression echoes a familiar rock/pop tradition but does so with an inventiveness that betrays the group’s strong understanding of harmonic function. The occasional unexpected modulations and heavily syncopated vocal melodies give the song a unique twist within the pop genre.

Chords in the Verse 1 section of I Will by The Beatles are:

[‘C’, ‘Am’, ‘Dm7’, ‘G7’, ‘C’, ‘Am’, ‘Em’, ‘C7’, ‘F’, ‘G’, ‘Am’, ‘C7’, ‘F’, ‘G’, ‘C’, ‘Am’, ‘Dm7’, ‘G(sus4)’]
