Ariadne auf Naxos
At a sumptuous home, two theatre troupes are preparing for their performances: a commedia dell’arte group, led by the comedienne Zerbinetta, and an opera company presenting a serious opera, Ariadne auf Naxos. The Major-domo announces that, to save time, both entertainments must be performed simultaneously.
The idealistic young Composer is loath to permit any changes to his opera. But when his teacher, the Music Master, points out that his pay depends on accepting the situation, and when Zerbinetta turns her charms upon him, he complies. When he fully realises to what he has agreed, he storms out.
Ariadne, who has been abandoned by Theseus, laments her lost love and yearns for death. Zerbinetta and her four companions from the commedia dell’arte troupe attempt to cheer Ariadne by singing and dancing, but without success. Zerbinetta insists that the best way to cure a broken heart is to find another love. Each of the four commedia men pursues Zerbinetta.
Naiad, Dryad and Echo announce the arrival of a stranger. Ariadne assumes it is the messenger of death, but in fact it is Bacchus, who falls instantly in love with Ariadne. As Ariadne and Bacchus celebrate their love, Zerbinetta claims that she was right all along.
