“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.

“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.

“And I Love Her” is a masterful composition by The Beatles that beautifully demonstrates their ability to mix pop songwriting with complexities of harmonic journey. The song is in the key of E Major, which is unique for being a popular song written by the Beatles in a major key. The main repeating chord progression of the Verse 3 is a progression that modulates between F# minor (the relative minor of A Major, which is the subdominant of E Major), and C# minor (the relative minor of E Major, the original key). The progression’s use of E6 at the end, which is a borrowed chord from the parallel minor (E minor), adds a unique flavor of sixth interval. Finally, it concludes on E6, a somewhat uncommon way to ground a song within a major key.

Chord Progression Analysis

**

Together, the chords form the following progression:

`C#m – C – E/B – E/G#`

In relation to the C# minor key, they are:

`C#m (‘i’) – C Major (‘♭VII’) – E Major/B (‘III/V’) – E Major/G# (‘III’)`

This repeats and forms the harmonic foundation for the verse of the song.

The `C Major` is a borrowed chord from the parallel key, C# Major. The `E Major/B` and `E Major/G#` are slash chords that implies a melodic movement in the bass.

Similar Chord Progressions

The use of borrowed chords from the parallel major/minor key is quite common in popular music. Similar chord progressions can be found in the works of Radiohead and The Beatles among others.

For instance, Radiohead’s “Paranoid Android” contains a notable borrowed chord progression: `G – B – C – Cm` in the key of G.

`G Major (‘I’) – B Major (‘III’) – C Major (‘IV’) – C Minor (‘iv’)`

The `B Major` is borrowed from the parallel key, G minor, and the `C Minor` is similarly borrowed from G minor.

The Beatles’ “While My Guitar Gently Weeps” also showcases a borrowed chord: `A – Amaj7 – A7 – D`.

`A Major (‘I’) – A Major 7th (‘I7’) – A Dominant 7th (‘I7’) – D Major (‘IV’)`

Here, the `A Dominant 7th` is borrowed from the parallel minor key, A minor.

Musical Analysis

**

The chord progression stands out for its brooding and suspenseful atmosphere, which is heightened by the minor key tonality and the use of a borrowed chord. By borrowing the `C Major` chord from the parallel major key, an interesting contrast is created. This along with the atmospheric textures of the song lends a sense of unease and tension to the music.

The `E Major/B` and `E Major/G#` are slash chords, which indicate a specified bass note other than the root of the chord. In this case, the bass note moves from B to G# while the chord remains the same – E Major. This creates a smooth and intricate bass line within the chord progression.
