Titon et l'Aurore (English: "Tithonus and Aurora") is an opera in three acts and a prologue by the French composer Jean-Joseph de Mondonville which was first performed at the Académie royale de musique, Paris on 9 January 1753.
 The authorship of the libretto has been subject to debate; Mondonville's contemporaries ascribed the prologue to Antoine Houdar de la Motte and the three acts of the opera to the Abbé de La Marre.
 "Titon et l'Aurore" belongs to the genre known as the "pastorale héroïque".
 The work played an important role in the so-called Querelle des Bouffons, a dispute over the relative merits of the French and Italian operatic traditions which dominated the intellectual life of Paris in the early 1750s.
 The tremendous success of Mondonville's opera at its premiere was an important victory for the French camp (although their Italian rivals claimed that this was because they had been excluded from their seats by members of the army).
 "Titon" was one of Mondonville's most popular works and went on to enjoy several revivals during his lifetime.

The Singing Lesson is a chamber opera in three acts with music and libretto by Matthew Davidson.
 Based on three short stories ("The Garden Party", "The Singing Lesson", and "The Doll’s House") by New Zealand author Katherine Mansfield, the opera is very unusual in several respects.
 For instance, the three acts are not connected by a conventional plot, but instead by literary themes.
 Those themes are class conflict (Acts 1 and 3) and a marriage of convenience (Act 2).
 However, the overall literary theme for all three acts is delusion.
