Brightness and density are scored against this record's own sections, not against music in general — they say how its parts differ from each other, and nothing about how it compares to anything else.

Separated into parts by a source-separation model, so each lane is the instrument it names.

outro

Every moment against every other. Squares on the diagonal are sections; a bright patch off it is the record recognising itself — the second chorus meeting the first.

Measured from the YouTube master on . Section labels describe how the energy of the recording moves, not its musical form — a machine can see loudness climb and jump, it cannot hear a chorus arrive. Anything we were not confident enough to state is left out rather than shown with a caveat.

  1. Ranked No. 1 in Ambient

    Four chords, an enormous amount of room around them, and more emotional weight than most symphonies manage. It has soundtracked moon landings and funerals alike, and earns both.

  2. Picked by The Waxonia Desk — A Way In

    Four chords and an enormous amount of room around them. The best argument that ambient music is composition rather than absence, and the easiest one to hear on first listen.

  3. Picked by The Waxonia Desk — The Hundred

    Four minutes that have been used to sell everything and still cannot be cheapened. The purest demonstration that music can be a place rather than an event.
