Richter was originally a painter who came to the movies almost by chance. His interest in abstractions and fast rhythmic movements transferred them to his cinematographic work in his varied works, many of them in the Dadaist style, a movement in which his first works are framed. This documentary, whose original title is "Rennsymphonie", about an impressionist-style horse race, based on a superb montage and dominated by the effects of close-ups, overlaps and contrasts of images, sometimes with a devilish rhythm, was made as an introduction to the feature film "Ariadne in Hoppegarten" and could be included, in a certain sense, within the trend of "visual symphonies" ("Visual Symphonies2"), since it develops, in a musical way but only from images ( since she is originally mute), a day of racing at a racecourse.A figurative derivative of her abstract experiments, it is reflected in a superb dialogue between images of horses (with the race as a climax), the spectators themselves, and the environment the event takes place in. It is not isolated, since Richter produced similar documentaries, although of an advertising nature, for companies such as various advertisements for tobacco, footwear or automobiles, among others.
