“Glory Box” by Portishead is a Trip Hop masterpiece which blends elements of blues, rock, soul, and electronic music together in an innovative and influential way. The song’s chord progression, as illustrated by the verse, is D minor, D minor with C in the bass (notated as Dm/C), B minor 7 flat 5, and B flat major 7. This particular chord progression gives an overall melancholy and haunting feeling throughout the song and sets the tone for the track.

The song “Roads” by Portishead features a haunting yet melodic chord progression reminiscent of the minor key-oriented pop/rock of the 90’s. It combines chords from the key of A minor along with a borrowed chord from the parallel major key to create a moody, atmospheric soundscape typical of the trip-hop genre.

The piece “3’s and 7’s” by Queens of The Stone Age illustrates a fascinating blend of minor and major tonality, accented dissonances, and unexpected harmonic turns, which is characteristic of the band’s stoner rock and alternative metal style. The verse 2 chord progression is in A# minor and it sticks to a fairly repetitive three-chord progression of A#m – G# – F.

The progression is in the key of C major. The use of the Bb major is known as modal interchange, where a chord that is not in the key is borrowed from a parallel key, which in this case is C minor. This contributes an interesting tone color to the overall sound. The chord progression does consist a use of slash chords (C/B, C/G) which adds a more complex bassline creating a more harmonically active feeling, and yielding more tension and release.

The chord progression in Verse 2 of Pink Floyd’s “Welcome to the Machine” is a complex and somewhat unconventional progression. It primarily features chords from the E natural minor scale, with some borrowed chords from the parallel E major scale. The progression creates an atmospheric and moody soundscape that is characteristic of Pink Floyd’s music, especially in their album “Wish You Were Here.” It also displays a certain level of sophistication in the harmony which underscores Pink Floyd’s musical depth.

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’]
