The Crystal Liturgy, from the name of the first movement of the Quartet for the End of Time, is the ideal introduction to the world of Olivier Messiaen (1908-1992) whose original work is like a singular planet rotating around nature and faith, its stars. The film uses rare documents: we see Messiaen giving lessons at the Conservatoire de Paris with generous simplicity; we follow him down the parths of nature as he writes down the songs the birds teach him; we admire Yvonne Loriod, his wife, student and accomplice, who plays the works of her teacher… He is also interviewed at length, at different ages, which enables us to understand the particularity of his creative process and to understand the mysteries of a vocation: how could an eight-year-old boy, living alone with a mother who wasn't a musician, in a family where there were no musicians, know beyond the shadow of a doubt that he was a musician?

《费加罗的婚礼》是莫扎特最具代表性的诙谐歌剧，故事是由费加罗及其所爱的苏珊娜共同布置着新房展开，紧接着是一连串的闹剧发生在他们与他们的雇主、伯爵、伯爵夫人，以及另一位侍童之间，最后这一切混乱又在闹剧中以喜剧收场。正如前面所提到的，莫扎特并没有将全剧的精彩片断浓缩至序曲中，而是讲整个歌剧诙谐的精神，放入了这个曲似奏鸣曲式架构组成的序曲中。
