This experimental film, "Allegretto," where visuals and action are meticulously synchronized with music, promises an extraordinary sensory experience. "Allegretto" originally refers to a rapid tempo in musical compositions, and in this film, it is used to present a segment of jazz music composed by Ralph Rainger. Rows of orderly concentric circles ripple outward in radial patterns, perfectly following the exquisite background music. They meet and overlap on the screen, creating a sense of power between peaks and troughs. Colorful diamonds fly about everywhere, resembling lively little fish or dazzling, multicolored gems. However, the music abruptly shifts from its earlier conservative style, becoming urgent and hysterical. These highly ordered abstract geometric shapes, guided by the unstable tones, dance in a magnificent ballet. This abstract avant-garde animated short, produced in 1936, was directed by German filmmaker Oskar Fischinger. Oskar dedicated himself to achieving dramatic visual effects through dynamic abstract geometric forms. In the early 1930s, he began experimenting with synchronized sound in his experimental films, seeking to uncover the intrinsic connection between moving visual patterns and musical emotion. "Allegretto" employs these highly experimental colors and lines in an attempt to explore profound aesthetic and philosophical inner connections.
