Messiaen on Birds I

"Messiaen found birdsong fascinating; he believed birds to be the greatest musicians and considered himself as much an ornithologist as a composer. He notated birdsongs worldwide, and he incorporated birdsong transcriptions into a majority of his music. His innovative use of colour, his personal conception of the relationship between time and music, his use of birdsong, and his intent to express religious ideas all combine to make Messiaen's musical style notably distinctive."
