Labyrinth is an opera in one act by composer Gian Carlo Menotti.
 The work was commissioned for television by the NBC Opera Theatre and uses an English language libretto by the composer.
 Unlike Menotti's previous television operas, such as "Amahl and the Night Visitors", this opera was written with no intention of being moved to live stage performance later.
 Menotti intended for this work to utilize the special effects unique to television which could not be recreated in live theatre.
 As a result, NBC's television production of the opera is the only performance the work has received.
 At its premiere in March 1963 the opera was mainly criticized by the press for its trite use of allegory and music which rejected the avante garde in favour of romanticism.
 Critic Harold C. Schonberg stated in his review in "The New York Times" that, "Menotti falls back on the procedures he has always used: the scraps of canonic imitation, the stretches of parlando, the Puccini like melodies, the banal waltz themes... [It] ended up an allegory that had all the dimension of a Mobius strip: an example of slick television and cinema of the 1960s wedded pretty much to music of the 1890s... On the whole "Labyrinth" is one of the thinnest musical concoctions Menotti has ever put together.
The Medium is a short (one-hour-long) two-act dramatic opera with words and music by Gian Carlo Menotti.

 The Broadway production took place on May 1, 1947, at the Ethel Barrymore Theater with the same cast.
The Hero is a two-act opera by Italian-American composer Gian Carlo Menotti.
 Commissioned by the Opera Company of Philadelphia, the work premiered at the Philadelphia Academy of Music on June 1, 1976.
 At this point of his career, Menotti's style of composition, which rejected the avant-garde, was out of favor with the classical music world. "
Time" stated in its review of the opera, "Most of Menotti's music is passable Puccini: melodic, easy to take—and totally beside the point in 1976."
Amelia al ballo ("Amelia Goes to the Ball") is a one-act "opera buffa" by Gian Carlo Menotti, who set his own Italian libretto.
 Composed during 1936 when Menotti was in his mid-twenties, it was the composer's first mature opera and first critical success.
