“Sour Times” by Portishead is a song with a complex and intriguing chord progression. It blends minor key tonality with modulations and chromaticism to give it a mysterious and brooding atmosphere.

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.

The chord progression in Verse 2 of Kali Uchis’s “After The Storm” is a mix of diatonic and chromatic chords that create an interesting neo-soul groove. The harmony is primarily based on G# minor, featuring the G#m7 and A#m7 as primary chords, and the D#aug chord adds tension and release within the progression. Additionally, the use of the D#aug chord acts as a chromatic mediant between G#m7 and A#m7.

“Rocky Raccoon” by The Beatles incorporates chords commonly associated with the genre of folk or country music. It is primarily built on a repetitive chord progression which consists of Am7, D7sus4, D7, G7, C, and C/B. There’s also a use of plenty of sevenths and suspensions to create a slightly jazzy feel. It’s also worth noting The Beatles’ penchant for chords that provide a mix of major and minor tonalities.

The given chord progression belongs to the verse 2 of the song “Apocalypse Please” by Muse. This progression reflects the band’s signature style that combines elements of rock, classical, and electronic music. The chords follow a pattern that combines both diatonic and chromatic movement, creating a dramatic and intense feel. A unique feature in this progression is the use of slash chords, which adds further harmonic interest.

Chord Progression Analysis

– C# minor (i)
– C major (bVI)
– E major over B (V/III)
– E major over G# (V/vi)

markdown
C# minor – the tonic chord, or home chord, in the key of C# minor.
C major – a borrowed chord from the parallel major key (C# major), also known as the Picardy third.
E major over B, E major over G# – inverted V chords that provide strong resolution back to the tonic, adding interest with different bass notes.

Similar Chord Progressions

A chord progression somewhat similar to this can be found in Radiohead’s “Exit Music (For a Film)”, which also makes use of mode mixture and chromaticism:

– A minor (i)
– G major (bVII)
– E minor over B (v/III)
– C major over G (bIII/VI)

Such unconventional chord progressions can also be found in songs by bands such as Massive Attack and Björk, who are also pioneers of the trip-hop genre.

For example, Massive Attack’s “Teardrop” uses a progression that also features modal interchange and a chromatic descending line:

– F# minor (i)
– F major (bVI)
– D# minor over B (vii/iii)
– A# minor over G# (iv/VI)

These examples show the innovative and intricate blending of elements from jazz, funk, and electronica characteristic of the trip-hop genre.

Musical Analysis

C# minor is the tonic or home chord of this progression. The C major that follows is a borrowed chord from the parallel major key (C# major); this is an example of mode mixture or modal interchange, where chords from a parallel key are used to increase the harmonic interest of a piece.

The E over B and E over G# are inversions of the E major chord, which is the dominant (V) in the key of C# minor. The changing bass note—first B, then G#—creates smooth voice leading and adds harmonic interest.
