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 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.

The chorus of Taylor Swift’s “Anti-Hero” utilizes a chord progression that elevates the song’s emotional resonance, serving as a climactic counterpart to the reflective verses. This section combines lush harmonies with straightforward pop sensibilities, creating a poignant and memorable musical moment that aligns with the song’s thematic exploration of self-awareness and complexity.

“Boulevard of Broken Dreams” by Green Day, released in 2004, is an alt-rock anthem that largely follows a 4-chord progression throughout the song. The key signature of the song is E minor (derived from the root chord), and essentially all chords used in the song are diatonic, meaning they are derived from the scales of the key. The chorus shifts to a progression in C Major. However, it returns to E minor at the end.

The chorus of Pink Floyd’s “Comfortably Numb” is a perfect example of their signature sound, combining both rock and progressive elements. The harmonic structure is simple yet effective, providing a sense of resolution and stability throughout the progression. This, combined with the smooth melodic lines, gives listeners a feeling of being “comfortably numb.”

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.
