Structures, Book I is a composition for two pianos, composed by Pierre Boulez in 1952. It premiered in Paris on March 2, 1953, performed by Yvonne Loriod and Boulez himself. The piece is divided into two movements, each with its own distinct characteristics. The first movement is marked "Livre" (book) and is characterized by its use of serialism. Boulez uses a twelve-tone row as the basis for the entire movement, with each note of the row being used in a specific order. The movement is also characterized by its use of complex rhythms and textures, with the two pianos often playing different rhythms and patterns simultaneously. The second movement is marked "Commentaire" (commentary) and is more improvisational in nature. Boulez uses a series of short musical fragments, which are then developed and expanded upon throughout the movement. The two pianos often play in unison, creating a sense of unity and cohesion. Overall, Structures, Book I is a challenging and complex work that showcases Boulez's mastery of serialism and his innovative approach to composition. The piece has become a staple of the modern piano repertoire and continues to be studied and performed by pianists around the world.
