“Sour Times” by Portishead is largely written in the key of C# minor, with elements of modal interchange and chromaticism that contribute to its haunting, dark sound. The song exhibits a remarkable amount of harmonic complexity and non-diatonic harmony, which is a defining characteristic of the trip-hop genre. The piece makes use of intricate inversions and chromatic voice leading, along with a frequent use of sevenths and diminished chords for added tension.
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.
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.
“Give Me The Night” is a jazz-funk composition with a rich harmonic texture and a catchy melody. It was produced by Quincy Jones and released in 1980.

“Ceilings” by Lizzy McAlpine, draws its magic from a mix of interesting chord progressions and different rhythms. The use of added notes in several chords (Cadd9, Emadd9) introduces additional color into the mix, creating a rich and thoughtful atmosphere. The tonality of the song is in G Major, despite the liberal use of the Cadd9 in the progression. We’ll use this tonality for the Roman numerals.
“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.
