Ariadne auf Naxos
The composer is stressed. His little opera ensemble is about to perform Ariadne auf Naxos, a grandiose opera of his own making, at the home of a wealthy man. But the very same evening a troupe of players led by the colourful Zerbinetta will also perform, and the two ensembles fight over who is to go first.
The threat of cuts is driving the earnest composer to near breakdown. This is the comic prologue to the opera about Ariadne that the audience will be attending after the intermission.
