  In the “free art” of design, parallel lines, and especially vertical stripes, are expressive of iki: almost all the other beautiful patterns developed by Japanese fabric arts, since they often involve curved lines, are un-iki. The only colors that embody iki are certain grays, browns, and blues. In architecture the small (four-and-a-half mat) Zen teahouse is a paradigm of iki, especially insofar as it initiates an interplay between wood and bamboo. Lighting must be subdued: indirect daylight or else the kind of illumination provided by a paper lantern. The scales, melodies, and rhythms of various kinds of music are correspondingly iki, insofar as (alluding to Goethe, Schelling, and Schopenhauer)“Architecture is frozen music, and music as flowing architecture” (Nara, 41–51).
