The song “3 Libras Acoustic Live” by A Perfect Circle oscillates between an A major and a C# minor structure, with a D major introduced at the end of the progression. The dominant chords are A (represented as Asus2) and C# (represented as C#m). The final D chord can be seen as a modulation, adding a somewhat unexpected resolution that doesn’t adhere to the traditional rules of tonic-dominant resolution in either major or minor keys.

The progression from B to A to E is a common progression in pop and rock music. This progression utilizes diatonic and non-diatonic chords, meaning that the chords all belong to the same key and it suggests the use of borrowed chords. A Perfect Circle tends to use a lot of downward motion in their chord progressions, moving from higher to lower pitches, which can give their music a distinct ‘heavy’ feel.

“Tonight, Tonight” by The Smashing Pumpkins draws from the band’s unique style of alternative rock influenced by a distinct palette of harmonic choices. Particularly in the songwriting of Billy Corgan (the band’s primary songwriter), the band tends to use a mix of common and uncommon chords, together with a tendency of exploring different tonalities. Often, the chord changes are driven by guitar inversions, suspensions, or additions.

The chord progression in the chorus of “Nude” by Radiohead features a mix of diatonic and borrowed chords, with some added tensions for additional color. It reflects the band’s signature style of blending unexpected harmonic elements to create a unique and evocative sound. In particular, the mix of major and minor chords with added tensions lends a sense of both familiarity and unconventionality to the progression.

As this song has a distinct classical rock sound, you’ll see a mixture of major and minor chords. The progression is in the key of E major. The use of seventh chords and suspended chords provides a dense harmonic texture.

Chord Progression

Chord Progression Analysis

The song appears to be in the key of E Minor. The configuration as presented suggests a repeated sequence of E, C, and F chords during the chorus. This can be broken down into the following:

E Major (‘I’)
C Major (‘VI’)
F Major (‘II’)

Notably, the ‘II’ chord (F Major) seems to be a borrowed chord, since in the key of E minor, the ‘II’ chord is typically diminished (F#dim). Borrowed chords are a technique that can add interest and unexpected twists to a composition.

Similar Chord Progressions

1. Radiohead’s “Creep” also uses a similar chord progression (I – III – IV – iv) although with a major key center. It also borrows the ‘iv’ chord from the parallel minor key, again creating an unexpected twist similar to the ‘II’ in “3 Libras.”

Chord progression:
G Major (‘I’) -> B Major (‘III’) -> C Major (‘IV’) -> C minor (‘iv’)

2. The Beatles’ “While My Guitar Gently Weeps” also uses a I – VI – II progression in a minor key, similar to “3 Libras Acoustic Live.”

Chord progression:
Am (‘i’) -> F Major(‘VI’) -> D Major(‘II’)

Please note that exact musical phenomena like borrowed chords and their specific effects can differ between songs due to other factors such as melody, rhythm, instrumentation, or lyrics.

Musical Analysis

The borrowed ‘II’ chord creates a surprise in the harmony, as its Major quality isn’t expected within the typical key of E minor. While II-V-I progressions are very common in jazz, in the rock context (such as A Perfect Circle’s music), they are less standard and thus create a distinctive sound. As this progression repeats, it creates a loop of unresolved tension. This contributes to the overall moody and melancholy character of the song.

Overall Analysis

“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.

Style Analysis

The style of “3 Libras Acoustic Live” is distinguished by its heavy melodic emphasis and its unorthodox harmonic choices. The borrowed chord, and the ethereal, brooding aesthetic it helps to produce, is fitting for A Perfect Circle’s alternative rock style. The cyclical progression and repetition also contribute to a sense of introspection and ongoing struggle, consistent with the lyrical themes of loneliness and alienation.
