Russian modernist experiments in sensory communication include the interplay of sound and light in Alexander Scriabin’s symphonic mysteries as well as colored sounds in Wassily Kandinsky’s stage compositions.

This article seeks to assess the role of music and sound in synesthetic experiments of Scriabin and Kandinsky and place their theory and practice within the larger philosophical, artistic, and scientific contexts of their period and beyond.
