A white pupil burns at dead centre, ringed by a blush (F) and spring green (A) iris, with grey-blue percussion gathered at the rim like lashes: this portrait looks back. Its strangest truth arrives at the loudest, most crowded moment, when the massed voices flood in and the ring edges go clean, wobble at its lowest reading of the entire song. A climax that rests. An F major hymn, its promise kept.

Harmonically this song never leaves: codominant Bb (dusty rose) and F (blush) hold the centre from first second to last, and the loudness span is 4.2 decibels. The drama lives at the rim, where 859 sharp attacks against 441 available beats crowd the edge as a spiky teal percussion fringe, nearly 2 hits for every pulse. All that motion, running in place: that is the groove, drawn.

Two materials refuse to merge. The interior is a braid of soft violet (Ab), spring green (A), and jade (E), three pitch centres within a single percentage point of one another, so nothing owns the harmony. The beats are drawn in fired clay at the rim, a palette belonging to no pitch anywhere inside, and where they erupt hardest, around 3:30, the ring edges settle to their smoothest of the whole song: emergency, drawn as calm.

For two-thirds of this portrait the ring edges ripple and fray while the harmony refuses to move: one chord, wavering. In the final stretch the edges go smooth, and the loudest moment of the record arrives inside that calm, in a 7-second span where the voice has dropped out entirely. Nothing in the harmony resolved. What let go was the panic.

All 12 pitch classes are present and held almost evenly; the two nearest the top, coral (C) and teal (B), finish in a dead tie a half-step apart. There is no home key to rest on, and the ring edges wobble nearly everywhere under a voice that never rises: the loudest moment of the whole record is the greeting, 17 seconds in. A song that asks its question and answers by not answering.

Two colours refuse to settle who wins: warm coral (C) and spring green (A) sit in a near-tie at the core, and the harmony that opens the song is the harmony that closes it. The ring edges run smooth for almost the entire span, harmonic rest under restless verses. Then, only at the very end, the edges go wavy and the white vocal thread nearly doubles in density: the voice rises exactly where believing gets hard.

Spring green (A) is home here, among the dominant pitches in 10 of the song's 11 sections. The exception is a 6-second window around 2:20 where the green falls out, the rings thin almost to nothing, and the edges reach their most violent wobble in the song: despair given its own room. Through that collapse the violet percussion at the rim holds full density; the pulse carries what the harmony drops.

The white vocal thread is present for 9% of the runtime; you have to hunt for it. It surfaces in short bright dashes at the most exposed admissions, then withdraws, and the last third of the record carries no voice at all: the blush (F) and coral (C) rings, the two warmest colours in the palette, spin on alone. A portrait of warmth that never once helps.

The descent is not in the harmony: the field stays anchored on spring green (A) from cliff to escape. What fails is the light. The opening rings are the brightest in the picture, glassy attack near 6,665 Hz, and two-thirds through the brightness falls below 1,000 Hz, the rings thin by a third, and the weave opens into black at the lower edge, exactly where the lyric touches bottom.

The body of this portrait is jade (E), ring after ring: the home key is dominant in 14 of the song's 18 sections, and the whole disc leans off-axis without ever breaking from it. That lean is the song: a vow to escape, pinned to one pitch, drifting but never free. The dynamic range is 3 decibels, one sustained roar, with a single dark held breath just past the middle.

The core of this portrait is grey: 9 pitch classes crowd it so evenly that no single home wins, an organized avalanche averaging to a cloud. The loudest instant lands early, at 2:14, in the first orchestral climb. The most unstable edge in the whole disc comes at the very end, on the famous held E major chord: a resolution sustained so long it stops being an answer and becomes a presence.
