Le toréador, ou L'accord parfait (The Toreador, or The Perfect Agreement) is an opéra comique in two acts by the French composer Adolphe Adam with a libretto by Thomas-Marie-François Sauvage. It was first performed at the Opéra-Comique, Paris on May 18, 1849. It was a huge success and the work regularly appeared in the repertoire of the Opéra-Comique until 1869. Adam made use of several familiar pieces of music in the score. The most famous number is a series of variations on Ah! vous dirai-je, maman (better known as the melody of Twinkle, twinkle, little star in the English-speaking world). The opera also quotes the aria Tandis que tout sommeille from Grétry's L'amant jaloux and Je brûlerai d'une flamme éternelle from the same composer's Le tableau parlant as well as popular folk tunes, including the Spanish fandango, cachucha and follia. In spite of this, there is little attempt to give the score local colour. The opera was originally intended to be a single act but was split in two to allow the soprano time to recover her breath in a taxing role.
Place: The garden of Don Belflor's house in Barcelona
Coraline, a former opera singer from Paris, is unhappily married to the retired bullfighter Don Belflor. She remembers how a flute-player, Tracolin, was in love with her. At this point, Tracolin himself appears in Barcelona, intent on renewing his acquaintance with Coraline. The two exchange love letters over the garden wall. Tracolin saves Don Belfor from an attack by ruffians and is invited into his house. He claims he is acting as a go-between for a dancer at the opera, Caritéa, who has fallen in love with Don Belflor. The old man is flattered but asks for further proof and Tracolin can think of no other recourse but to give him Coraline's letter. As Don Belflor is leaving for liaison with Caritéa, Coraline accuses him of adultery. In his confusion Don Belflor drops the letter on the floor. The horrified Coraline believes that she has been found out.
