The “Glory Box” by Portishead chorus progression is based in D minor and moves between this primary D minor chord and three other chords: Dm/C, Bm7b5, and Bbmaj7. The Dm/C chord is the same as the D minor, but with a different note in the bass (C). The Bm7b5 is a half-diminished chord. The Bbmaj7 is major seventh chord.

“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.

“Undone – The Sweater Song” by Weezer is a grunge rock song from their debut album, “Weezer (The Blue Album)” released in 1994. The chord progression in Verse 2 seems to blend elements from both pop and rock genres, with some diatonic chords and a borrowed chord that adds an unexpected twist.

“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.

Verse 2 of Grizzly Bear’s “Yet Again” presents a straightforward harmonic progression that is common in pop and indie rock music. This series of chords is mainly built around the key of A minor, and uses diatonic chords (those that naturally occur within the key) of this key. The recurring sequence (Am, G, C, F, F, Em, C, Dm) indicates a strong sense of familiarity and predictability, characteristic of many pop/rock anthologies.

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’]
