The Yellow Sound (in German, Der Gelbe Klang) is an experimental theater piece originated by the Russian artist Wassily Kandinsky.

[3] Kandinsky's pieces were part of a larger trend of their era that addressed color theory and synesthesia in works that blended multiple art forms and media.

He and his Blue Rider colleagues, including Franz Marc, August Macke, and Alfred Kubin, worked intensively on a planned 1914 Munich production, but it was cancelled by the outbreak of World War I.

[7] There has also been productions at the Alte Oper, Frankfurt am Main (7–8 September 1982) the Theatre im National, Bern Switzerland (12–15 February 1987) and the NIA Centre, Manchester on 21 March 1992.

A child in white and an adult performer in black represent life and death; other figures are costumed in single colors, including five "intensely yellow giants (as large as possible)" and "vague red creatures, somewhat suggesting birds...." Drawing on elements of Symbolism and Expressionism (while and anticipating Surrealism), Kandinsky's work had a strong influence on German theater innovator Lothar Schreyer, who "built a whole theory of performance on the expressive process first suggested in The Yellow Sound.
