122 avenue Mozart — Hôtel Guimard - Paris 16, 17h00

One of the 72 Facets of Paris, a series born of a piano waltz of the same name: the artist gave each of its seventy-two measures the harmony of a Parisian place at a given hour, then painted each harmony into colour and form through his ideamorphic method. The waltz eases now, the afternoon waning. From the chord B♭−9 it draws the spirit of Guimard's own Hôtel Guimard on avenue Mozart at five: grey and magenta, a burning orange disc, white, blue and teal — the architect's house in the waning light. It holds the square (column 7, row 4) of the mosaic, which fully assembled forms an abstract portrait of Paris.
