At the beginning of the twentieth-century, social, political, and economic changes had a huge impact on music. Technology also played a crucial role in music development. Composers started experimenting with an increasingly dissonant pitch language. Melody, in the traditional way, was not recognizable. One of the most prominent composers of the twentieth-century was Olivier Messiaen. The purpose of this research is to introduce his compositional technique and his musical language as well as to gain an in-depth knowledge of his piano music. Messiaen derived his compositional technique from variety of sources, such as Greek rhythms, Hindu rhythms, and bird calls. He was one of the leading composers who made his music rhythmically intriguing and appealing. He frequently used rhythms of added values, augmented and diminished rhythms, non-retrogradable rhythms, and polyrhythms in his compositions. He was also an ornithologist. He spent lot of time transcribing bird calls. The Technique of My Musical Language, the book written by the composer himself, is the main source of this research as he introduces his unique compositional methods with many examples. Learning about his compositional technique is of tremendous help in understanding his musical language, his ideology, and the performance of his music.
