The track opens with its whole architecture carried by the bass alone. The figure walks three pitches around F, E♭ and C, spelling the root and the flat-seven and the fifth of an F-centered field. No third appears anywhere in this riff, so the bass states an F with no major third and no minor third in it.
That absent third becomes the central question of the entire song. The bass holds the terrain for four bars with no rhythm guitar and no voice present yet. A listener learns the dark, modal ground of the piece while no word has entered the room.
The verse keeps the engine fixed and hands every color to the voice. The bass repeats the E♭ and F and C cell under each bar with no third inside it. The rhythm guitar stacks E♭, C and F together, a third-less voicing, neither major nor minor.
The singer fills the gap the instruments leave open. The opening line moves down through C and B♭, then reaches A♮ on the word "for", the major third the bass does not spell. That A♮ flashes one bar of brightness across an otherwise dark field, then falls toward E♭ on the held word "favor".
The chart labels the chord under that A♮ as a diminished shape over E♭. What the ear takes from the bar stays simpler and stronger than the label. One sung pitch supplies the major third the whole band keeps withholding.
The pre-chorus keeps the floor on a single F pedal and lets the vocal swing across it. The bass plants F under almost every beat, with brief E♭ and C touches around it. The harmony stays an F sus and F7 shape, the third still left out of the instruments.
The voice settles on B♭, the suspended fourth above F, for the opening lines about cooking and washing. It steps up to C, the fifth, for feeding you grapes, then reaches A♮ once more on the word "make" in make you a symphony. The same A-natural from the verse returns as the one bright third inside an otherwise third-less room.
That A on "make" ties the section back to the verse thesis. The promises pile up while the harmony refuses to move off F. One sung major third carries the only lift the bed will allow.
The chorus finally moves the floor and walks the flat side. The roots step D♭5 down to F5 and up to C5, a borrowed flat-six into the home F and out to the dominant. Every one of those chords are a bare power shape, so the wheel keeps turning and no third ever enters in the guitars.
The voice carries the title line across the moving roots. On the words I keep thinking it climbs to E♮, the major seventh of the home F, a sharp leading-tone brightness over the dark wheel. It falls to C, the fifth, on still in love, then the band lifts up to the C5 the whole record keeps circling.
That E♮ is the chorus answer to the verse A♮. One song, two raised tones the bass never spells, both placed in the voice. The dominant C5 closes the wheel and refuses to resolve here.
The Y part pins the bass to F harder than any other section, ninety-six F hits against a handful of others. The chords ring F sus2 and F sus4 and plain F5, the suspensions trading the missing third for an open second or fourth. The voice floats C and E♭ over that pedal on you love the sound and the long beating-heart line.
One detail pays off the whole record. Around the middle of the section the guitar stem flickers an F minor shape, the first time any instrument states a third at all. The band picks the minor third, A♭, after withholding both thirds for minutes, while the voice has spent the song reaching toward the major one.
So the two thirds finally sound in the same song from opposite sources. The instruments lean minor for one moment, the voice has leaned major throughout. The pedal holds F under both readings without choosing.
The outro states the cadence the whole song kept avoiding. The roots walk B♭5 up to C5 and home to F5 across the closing minute. The C5 is the dominant the verse and chorus circled for the entire record, and here it finally falls to F.
The resolution arrives without ever picking a quality. The last chords read F5 and F sus2, the home root with a fifth and an open second, the third still absent at the final cadence. The song answers its dominant and keeps its central question open in the same gesture.
So the close stays true to the opening. The bass riff named F with no third in the first four bars, and the last bar names F with no third again. Only the voice ever spelled a major third across the whole song.
