Styled a "festa teatrale", "Le feste d'Apollo" consists of a prologue and three self-contained acts on the model of French "opéra-ballet" (the court of Parma was passionately interested in French culture).
 Gluck knew the Archduchess Maria Amalia well as she had sung in two of his operas, "Il Parnaso confuso" and "La corona", in Vienna.
 The composer recycled a lot of music from his earlier operas in the score of "Le feste".
 In fact, the whole of the third act, "Orfeo", is a shorter reworking of his most famous piece, "Orfeo ed Euridice" (1762).
 The overture to the prologue is taken from "Telemaco".
 Gluck later reused some of the choruses in two of the operas he wrote for Paris, "Iphigénie en Aulide" and "Iphigénie en Tauride".
Rescue opera was a popular genre of opera in the late 18th and early 19th centuries in France and Germany.
 Generally, rescue operas deal with the rescue of a main character from danger and end with a happy dramatic resolution in which lofty humanistic ideals triumph over base motives.
 Operas with this kind of subject matter became popular in France around the time of the French Revolution; a number of such operas dealt with the rescue of a political prisoner.
 Stylistically and thematically, rescue opera was an outgrowth of the French bourgeois "opéra comique"; musically, it began a new tradition that would influence German Romantic opera and French grand opera.
 The most famous rescue opera is Ludwig van Beethoven's "Fidelio".
This is a list of the recordings of Gianni Schicchi, the third of a group of three one-act operas by Giacomo Puccini collectively known as "Il trittico"; the other operas are "Il tabarro" and "Suor Angelica".
 The three were premiered at the Metropolitan Opera on 14 December 1918, and for the next three years were always played together.
 After 1921, however, Puccini agreed that the operas could be performed separately. "
Gianni Schicchi" became the most popular and most frequently performed of the three, often paired with other works such as Maurice Ravel's "L'heure espagnole" and Richard Strauss's "Salome".
