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.

peak
sits at the top of this record's range
build
energy and brightness climbing without a break
lift
a short rise that does not resolve — a fill or a transition, not a build
breakdown
energy falling away mid-record, percussion thinning
outro
the closing fall
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.

    A woman on a beach insisting to herself that the drowned man will return. Amália is fado, and this is the performance that carried it out of Portugal without softening a syllable.
