'''''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.
