 Lully went on to produce "tragédies en musique" at the rate of at least one a year until his death in 1687 and they formed the bedrock of the French national operatic tradition for almost a century.As the name suggests, "tragédie en musique" was modelled on the French Classical tragedy of Corneille and Racine.Lully and Quinault replaced the confusingly elaborate Baroque plots favoured by the Italians with a much clearer five-act structure.
