This paper studies the process of Stravinsky's musical language prior to his most famous work The Rite of Spring was written in 1913. In this work, Stravinsky's diverse musical language and orchestration, evolved through Fire Bird and Petrushka, have matured and became his representative musical style. There are two important events in Stravinsky's life, one is an encounter with Rimsky-Korsakov, and the other is the collaboration with Diaghilev and going out into Paris, France. Rimsky-Korsakov helped Stravinsky understand orchestra and instrumentation accurately, and through this effort, Stravinsky created his unique orchestration style. Stravinsky's first work after studying with this well-informed teacher of orchestration was a symphony, and ballet music such as Fire Bird followed immediately. Quotations of folk melodies and dynamic rhythms, along with orchestration techniques for timbre became more conspicuous in his next work, Petrushka. Therefore, diverse expression styles through the use of Russian folk melodies, and characteristic rhythms all made their way to Stravinsky's inherent orchestration style crystallized in The Rite of Spring.
