This chord progression from the verse of Tame Impala’s “Alter Ego” suggests a key of C major due to the recurring instances of Cmaj7. However, the presence of certain chords like Bm7 and Dm suggests that Kevin Parker is creatively “borrowing” chords from the parallel and associated keys (C minor, D minor) to create colorful departures from the primary tonality. The use of extended chords (7ths) and suspended chords (Bsus4) adds a sense of complexity and sophistication to the harmony. As can be seen, the chord progression mostly oscillates between Cmaj7, Bsus4, Bm7 before moving to Dm and Gm towards the end of the verse.

The song seems to have a psychedelic pop/rock vibe reminiscing of the late ’60s and ’70s. The use of major seventh chords and repeated shifting between E Major and D Major hints at a sense of yearning and nostalgia, something that is commonly found in Tame Impala’s music.

“Maxwell’s Silver Hammer,” composed by Paul McCartney, is a pop song that sits in the key of D Major throughout. However, it does borrow chords from the parallel minor. This technique, known as modal interchange or borrowed chords, is common in popular music and especially in classical compositions by iconic bands like The Beatles.

The chord progression in the chorus of Radiohead’s “Knives Out” is an interesting and unconventional one, making use of some borrowed chords and a mix of major and minor tonalities. The overall style of the song can be described as alternative rock with some influences of jazz harmony and chromaticism, creating a unique and moody atmosphere. The progression is mostly diatonic, but it also incorporates some borrowed chords from parallel modes to add color and tension.

“Creep” by Radiohead is an alternative rock song in the key of G major, with a somewhat melancholic tone. The chord progression used is iconic, and it heavily relies on borrowed chords to create tension and resolution in the harmony. This use of chords creates a distinct sound that has become synonymous with the song.

Similar Chord Progressions

– “Because” by The Beatles has a similar use of a pattern of chords in the choruses, cycling between Emaj7, C#m, Cm, G#m, and G#m7.

– “Breathe” by Pink Floyd has a similar vibe with a revolving chord progression alternating between Bm7, A(add9), and Gmaj.

– “Marquee Moon” by Television presents a psychedelic sound with a similar vibe, the chord progression alternates between F#m, Emaj7, Dmaj7, C#m, Bm7, and Amaj7.

Bear in mind, none of these songs perfectly match ‘Alter Ego’, but they might have inspired aspects of it.

Musical Analysis

The progression starts with an ‘Am’ (i) and continuously alternates between ‘Fmaj7’ (VI) and ‘Em’ (v) chords for 9 times. This gives the feeling of suspension and tension, pairing well with the psychedelic rock genre. The pattern breaks at the ‘E’ (V) major chord, providing some predictable resolution. We then have a deceptive cadence with the ‘A’ (IV in A major) and ‘G’ (bVII in A major). The usage of ‘Cmaj7’ (III) and ‘Bsus4’ to ‘Bm7’ is similarly notable as these chords fall outside of the normal.

Overall Analysis

This chord progression is in the key of Am. The work can be seen as a mix of the Western tonal harmony, incorporating the use of inversions alongside nondiatonic chords. Tame Impala employs the elements of neo-psychedelia with unique chord progressions and arrangements. The alteration between two chords creates a revolving feeling, reinforcing the title “alter ego”.

Style Analysis

Tame Impala is known for their fusion of classic psychedelic rock with modern synthesized sounds, and ‘Alter Ego’ is no exception. The Meandering progression contributes to a “dream-like” state, matched with ethereal synth and guitar tones, harkening back to late ’60s and early ’70s influences like Pink Floyd. But there’s also a frequent incorporation of more modern sounds and effects that bring the music to the present. This track might also reflect the influence of jazz, notable in the usage of the maj7, m7, and sus4 extended chords.
