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.

“Roads” by Portishead is set in the key of Am, also known as A minor. In the verse, there is an interesting use of the flat major 7 (Fmaj7) chord. This chord is not typically found within the natural minor key but is considered a borrowed chord from the A major key. Thus, this use of said borrowed chord and its resolution to the E7 dominants gives the song a unique feel, contributing to its mesmerizing and emotive ambience. Portishead tends to blend the use of A minor and A Dorian modality in their music, especially apparent in this composition.

Feels Like We Only Go Backwards by Tame Impala uses very interesting chord progressions that convey a feeling of constant motion. The song is primarily in the key of F Major, as revealed by the majority of the chords (F, C, Gm). However, the chord progression in the verse introduces Dm and Cmaj7/G, showing some clever use of modal interchange, also known as borrowed chords.

“Since I’ve Been Loving You” by Led Zeppelin is a slow-tempo blues-rock song featuring a sophisticated and expressive chord progression that falls predominantly within the C minor key, standing out from the more traditional blues structures. The chords in the verse display a creative use of borrowed chords and chromaticism, contributing to the song’s moody and emotionally-evocative atmosphere. The progression is less common in rock music, which is what makes it characteristic of Led Zeppelin’s innovative musical explorations.

Musical Analysis

The song, by construction, is predominantly in E minor, though it explores tonal centers around various modes, such as E Aeolian and E Dorian. The verse moves from ‘Em’ (the 2nd degree), to ‘F’ (a chord borrowed from the parallel major or the E Phrygian mode, considered the flat 3rd degree), back again to ‘Em’.

The progression then drops to ‘C’ (7th degree in E minor), to ‘Am’ (4th degree), then uses another borrowed chord ‘Bb’ (borrowed from the E Locrian mode acting as flat 5th degree), and back to ‘Am’. The verse closes with a ‘G’ (3rd degree in E minor), adding a dimension of resolution.

Overall Analysis

“The Rip” by Portishead is a classic example of the Trip-hop genre. It features simple, yet effective harmonic progressions that offer a melancholic tone which is widely utilized in this genre. The distinctiveness of this particular chord progression lies on its subtle shifting between minor and major tonalities, as well as its use of borrowed chords.
