Are both Savitri and Le devin du village considered operas?
Savitri (opera) Sāvitri is a chamber opera in one act with music composed by Gustav Holst, his Opus 25, to his own libretto. The story is based on the episode of Savitri and Satyavan from the "Mahābhārata", which was also included in "Specimens of Old Indian Poetry" (Ralph Griffiths) and "Idylls from the Sanskrit". The opera features three solo singers, a wordless female chorus, and a chamber orchestra of 12 musicians (consisting of 2 Flutes, a Cor Anglais, 2 String Quartets and a Double Bass). Holst had made at least six earlier attempts at composing opera before arriving at "Sāvitri".
Die Schweizer Familie Die Schweizer Familie ("The Swiss Family") is an opera by the Austrian composer Joseph Weigl. It takes the form of a "Singspiel" in three acts. The libretto, by Ignaz Franz Castelli, is based on the vaudeville "Pauvre Jacques" (1807) by Charles-Augustin de Basson-Pierre and René de Chazet. The opera was first performed at the Theater am Kärntnertor in Vienna on 14 March 1809 and was a great success in German-speaking countries in the early 19th century.
