Olivier Messiaen (1908-1992) was a French organist and composer who was passionate about Ornithology and one of the mostimportant composers of his century. Inspired by Japanese music, he had a very special way of composing and his work can be identified by its complexity, its diatonic aspect, its harmony with limited transposition, its colour andits additive rhythms. He composed many works related to ornithology and birdsong, including the 'Treatise on rhythm, colour and ornithology' in 7 volumes.
