“And I Love Her” by The Beatles is predominantly set within the key of F# minor. Apart from the chorus that momentarily modulates to the key of D minor, the verses embrace a darker, melancholic atmosphere portrayed by the minor keys. The tonal structure and chord progressions in the song are reflective of the band’s exploration of intricate harmonies, going beyond the simple three-chord structures of many contemporary pop songs of the time.

“Perfect Situation” by Weezer is a pop-rock song that follows a standard verse-chorus format, with a strong focus on melody and harmony. The song is in the key of G major, and the chord progression provided is for the second verse. It features a simple, yet effective progression that creates a sense of movement and tension before resolving back to the tonic chord. This gives the song a very engaging, classic pop/rock feel.

“All My Loving” by The Beatles is a mid-tempo pop song written in the key of E minor for the verse and D Major for the bridge and outro, featuring a distinct, upbeat walking bassline. The grey, almost mournful verses, along with the brighter, major-toned bridges and chorus, create a juxtaposition of feelings within the piece. The bridge also highlights The Beatles’ use of secondary dominants and chromaticism. Concluding in the tonic key of D Major, the song has an interesting interplay between Em and D Major throughout, which could be perceived as a Em: i, VI, III, II and D: vi, V7, I, vi, IV, ii, I progression.

Similar Chord Progressions

1. “Bittersweet Symphony” by The Verve also uses similar rhythm and techniques. It sticks more to traditional diatonic harmony but bears a similar ambience.

– E (I)
– Bm7 (vi7)
– D (IV)
– A (V)

2. “Creep” by Radiohead, while more simple in construction, uses a chromatic mediant chord (Major III) unexpectedly, similar to how Portishead uses the Bbmaj7.

– G (I)
– B (III)
– C (IV)
– Cm (iv)

Musical Analysis

This progression repeats and forms the foundation for the verse. It begins on the tonic chord (Dm), lending a familiar, grounded feel. The bass then drops to play a Dm/C, essentially the same chord in 2nd inversion.

A shift to Bm7b5 creates a jazzy half-diminished sound, preparing for a move to Bbmaj7, a chromatic mediant relationship with the tonic Dm. The use of Bbmaj7 supports the overall melancholy and longing found throughout the song. It also forms a clear ii-V-I progression in the key of the relative major key (F Major), further emphasizing a jazz influence on the song, and yet it becomes an unexpected progression due to the return to the tonic minor afterward rather than resting on the relative major.

Overall Analysis

“Glory Box” by Portishead from the album Dummy (1994) presents a haunting and somewhat melancholy ambience commonly found in their trademark trip-hop style. This song, in particular, draws from a palette of jazz-influenced harmony. The chords used, their extensions, and inversions, conjure complexity beyond basic triadic harmony. The chord progression listed appears to be in the key of D minor and employs common jazz techniques like ii-V-I progressions and usage of the half-diminished chord.

Style Analysis

Portishead’s definitive style is trip-hop, a genre born in the UK, often featuring electronica-influenced beats, scratching, samples, and a dark, brooding atmosphere. “Glory Box” utilizes these features with its prominent looping sample, slow tempo, use of synths, and Beth Gibbons’ chilling vocals, over a predominantly minor chord progression, welcoming an overall melancholic mood.
