Synaesthetic simultanism of the arts (synaesthetics) is a branch of the Aesthetics of Complementarity based on the laws and principles of I. Miroshnik's New Coordinational Paradigm of Development, alternative dialectics, metaphysics, and eclecticism. Therefore, synaesthetic art, in which the Aesthetics of Complementarity is defined, is not a dialectical synthesis or eclectic integration of various types of art. Coordinational theory of musical and speech intoning by Irina M. Miroshnik realized in the System of performing interpretation of music. The synesthetic audio-visual composition (from lat. compositio - composing, linking, joining) the «SONG OF WAVES» is the process and result of selective cross-sensory coordination of complementary art images: the music of Franz Schubert, the poetry of Maximilian Voloshin and the image of the sea, presented simultaneously.
