“3 Libras Acoustic Live” by A Perfect Circle revolves around a rock ballad style with an alternative rock genre. It features distinctive chord progressions and some borrowing from outside of the primary key. The harmonic progression in the chorus is relatively simple but contributes to the melancholic and introspective atmosphere of the song.

The song “Gravity” by A Perfect Circle is principally in the key signature of C# minor, which is categorically a minor scale. The primary chords used throughout the song are C#m, F#, and G#m, with the addition of E occasionally. The overall chord progression is quite consistent, with alternative lose touch of the conventional nature of chord progressions in pop and rock music.

“Tiny Dancer” by Elton John, written in the key of C Major, is a classic example of elaborate pop song writing. The chord progression features common primary and secondary chords in the key of C Major, along with some borrowed chords to add color. This combination makes for a memorable and melodic song.

The most unique feature of the song is how it slowly changes to the key of C minor in the second half of the verse, making use of two borrowed chords. This is a powerful tool in songwriting, as it can dramatically affect the emotional tone of the song. Lastly, this song demonstrates Elton John’s use of Coloristic harmony, through chromatically altered chords.

“Something I Can Never Have” by Nine Inch Nails features a haunting and melancholic chord progression typical of the alternative rock and industrial rock genres. The tonality of the piece centers around the key of C major, with occasional borrowed chords and chromaticism adding emotional color and tension. The verse and chorus sections both feature a similar pattern of repeating chords as well as a descending bass line connecting the chords, giving the piece cohesion.

“A Hard Day’s Night” by The Beatles, despite seeming to have a simple structure, is quite unique in its musical composition. The progression varies from standard rock, pop, and folk structure by integrating unique transitions and slightly unconventional chord choices.

Similar Chord Progressions

One notable song with a similar chord progression is “Black” by Pearl Jam (in the key of E major):

Verse:
E – E – Aadd9 – Aadd9 – C#m – C#m – D – D

Chord/Roman numeral representation:
E (I) – E (I) – Aadd9 (IVadd9) – Aadd9 (IVadd9) – C#m (vi) – C#m (vi) – D (♭VII) – D (♭VII)

As with “3 Libras,” “Black” uses suspended and minor chords in its verse to create a dark, melancholic tone, and borrows the ♭VII from the parallel minor.

Musical Analysis

The extensive use of the Asus2 chord creates a sense of movement and unresolved tension in the piece. The frequent repetition of these specific chords contributes to that sense of movement and anticipation, which is then furthered by the unexpected turns to the C# minor and D major chords – borrowed chords from the parallel minor key.

Overall Analysis

The progression starts on the suspended II chord of the key, which anticipates resolution either to the tonic (E major) or the supertonic (F# minor). However, it instead moves to the dominant minor (C# minor), suggesting a borrowed chord from the parallel minor (E minor). The D major chord which concludes the progression is a borrowed II from E minor as well.

Style Analysis

“3 Libras” is characteristic of the alternative rock/post-grunge style of A Perfect Circle, particularly their exploration of darker harmonies and suspended tonality. The song’s style also incorporates elements of the progressive rock genre, demonstrated by its utilization of non-diatonic harmony and unusual chord progressions.
