A fascinating and unique composer Olivier Messiaen has pushed the limits of the conventions of composition to the extreme. Always extremely popular, Technique of my musical language contains the keys and the knowledge necessary to the understanding of the music of the composer. Admitted to the Paris Conservatoire at the age of 11, Olivier Messiaen (1908-1992) won numerous awards. Organist and composer but also avid ornithologist, Messiaen depicts the song of birds, in a large number of his works. His music is rhythmic, complex, harmonious, of a unique musical style and often uses modes with limited transposition. This prompted the composer to compile Technique de mon langage musical. This book contains illustrated texts of musical examples describing the unique elements of his music such as unmeasured music, rhythmic notation and modes with limited transposition. Technique of my musical language is an indispensable work for all lovers of the music of Messiaen.
