The song, “Sour Times” by Portishead, is in the key of C# minor. The chord progression of the chorus that you’ve provided swings between three chords (F#m7, Emaj7, D#7) four times before ending on a C#m chord. It suggests a II – I – VII progression in the chorus, which is rare and distinctive in contemporary music genres. This choice of chord progression creates a mysterious, dark, and contemplative mood, characteristic of the trip-hop genre that Portishead propounds.

The chord progression in Weezer’s “Perfect Situation” is a simple and repetitive progression that cycles through three chords, G, D, and Am, with D being used as a transitional or “passing” chord. This progression is based on the I – V – ii structure in the key of G major.

Similar Chord Progressions

A similar chord progression can be found in Radiohead’s “Paranoid Android” where the verse progression is Cm, Cm/B, Bm7b5, Bb7. They share similar elements including the mixed usage of major 7, diminished 5 and chromatic scale.

An exact track with this same progression is unlikely due to the rather unique nature of the progression, but songs in the same genre may share a similar mood. You will find many songs with similar vibes in the trip-hop genre, for example Massive Attack’s “Teardrop”.

Musical Analysis

Starting with a Dm chord, the song immediately gives a minor key atmosphere. The use of the Dm/C transition chord adds more tension, leading into the Bm7b5 which is a half-diminished chord and further adds to the tension and dark coloring of the piece. Lastly, the Bbmaj7 seems like a satisfying resolution after the tension built up but being a major chord, it adds a slightly bitter-sweet touch.

Overall Analysis

“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.

Style Analysis

“Glory Box”, like many trip-hop songs from the 90s, uses chromaticism and a minor key to elicit a melancholic mood, and combines this with sampled beats and electronica influences to create a darker sound. The use of minor and diminished chords, dominant sevenths and transitions demonstrate the jazz and blues elements often found in the genre.
