Once upon a time…
More than eight hundred years ago in Paris, workers began building a huge cathedral: Notre-Dame. At the same time, a musician called Léonin invented a new way of singing.
Before him, everyone in church sang the same tune. Léonin had the idea of making two voices sing at once: a low voice holding very long notes, like a carpet, and a high voice dancing above it with lots of little notes.
He wrote a big book of songs for every feast of the year. An English scholar called him “the best composer”. Thanks to Léonin, music in several voices started to grow, a bit like the cathedral rising towards the sky.
