Chromaticism

 

the augmenting or diminishing, by a semitone, of a degree in a diatonic scale, thereby heightening the degree’s tendency to gravitate toward an adjacent degree. A chromatic semitone lies between a diatonic degree and its augmented or diminished variant. The difference between a chromatic semitone and a diatonic semitone is that the notes of the chromatic semitone belong to a single degree; thus, the chromatic semitone C–C sharp contrasts with the diatonic semitone C–D flat. Chromatic alteration is indicated by signs of alteration, or accidentals. Alteration is more common than chromaticism, since every chromaticism is an alteration, but not every alteration is chromatic; an alteration in C major, for example, may lead to the establishment of a new key. Chromatic alteration is a real change in a diatonic degree in one voice; alteration occurs when the diatonic variant of that degree is given before the altered note in another voice or does not precede it at all.

(Godard, obsessed as always with connecting his work with the traditions of Western art, no doubt also has in mind the convention of three-dimensional painterly effects, from Renaissance parapet paintings to Chardin's drawers, pipes, and knives showily extending into the viewer's space.) Occasionally resorting to the Fauvist chromaticism he introduced in Eloge de l'amour, Godard allows his color-distorted images to flourish with intensely tinted flowers (psychedelic daisies, eye-searing poppies), shoved into the foreground so they may intrude into our space, and fixates on found loveliness: the bonfire of a woman's .Botticellian inane, a yellow X pulsing on a rain-slicked crosswalk, snowflakes glittering in the air like a slow shower of crystals.
