“Glory Box” by Portishead is primarily in the key of D minor, with some moments of modal interchange. The chord progression contains a distinct spice of jazz influence while remaining in the realm of synthesized trip-hop sound characterizing the band’s style.

The song “It’s A Fire” by Portishead features complex harmonic structures, distinguished by a fusion of pop, rock, and elements of jazz harmonies. The band, known for their trip-hop style, employ chromatically richer harmony and non-diatonic chord progressions in this piece. The chord progression of ‘It’s A Fire’ is consistent with this approach as we see the frequent use of suspended and minor chords alongside major ones, which creates a sense of unresolved tension. Borrowed chords, usually taken from the parallel minor or major key, are also used frequently to add stylistic color to the harmony.

“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.

“Honky Tonk Women” is a classic blues-infused rock and roll track, like many songs by The Rolling Stones. The guitar riffs and solo (though not discussed here) clearly show blues influence in their use of the pentatonic scale and common blues licks.

The chord progression used for verse 2 is a typical example of a classic rock chord progression, with a key center around G, utilizing the dominant chords of the key in a I-IV-I-V-IV-I-IV-I progression.

The chord progression featured in Radiohead’s “Motion Picture Soundtrack” Verse 2 is a four-chord loop that moves from G major to C major (acting as a suspension) and B minor (with an added 9th), creating an interesting mix of tonalities and suspensions. The progression establishes G major as the tonal center but continually moves away from it, creating a sense of ambiguity.

– Dm (i)
– Dm/C (i)

Dm/C is a borrowed chord. It’s essentially the i chord in 2nd inversion (i/C).

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.

Chords in the Verse 2 section of Glory Box by Portishead are:

[‘Dm’, ‘Dm/C’, ‘Bm7b5’, ‘Bbmaj7’, ‘Dm’, ‘Dm/C’, ‘Bm7b5’, ‘Bbmaj7’, ‘Dm’, ‘Dm/C’, ‘Bm7b5’, ‘Bbmaj7’]
