He who walks down the street, over there, is immersed in the
multiplicity of noises, murmurs, rhythms. […] By contrast, from the
window, the noises distinguish themselves, the flows separate out,
rhythms respond to another. […] No camera, no image or series of
images can show these rhythms. […] The observer in the window
knows that he takes his time as first reference, but that the first
impression displaces itself and includes the most diverse rhythms
on the condition that they remain to scale. […] Rhythms always
need a reference, the initial moment persists through other
perceived givens.
Henri Lefebvre, Rhythmanalysis
