The Yellow Sound (in German, Der Gelbe Klang) is an experimental theater piece originated by the Russian artist Wassily Kandinsky. Created in 1909, the work was first published in The Blue Rider Almanac in 1912. The Yellow Sound is a one-act opera without dialogue or conventional plot, divided into six "pictures." 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...."
