Vincenzo Salvatore Carmelo Francesco Bellini was an Italian opera composer, who was known for his long-flowing melodic lines for which he was named "the Swan of Catania". Many years later, in 1898, Giuseppe Verdi "praised the broad curves of Bellini's melody: 'there are extremely long melodies as no-one else had ever made before'."

Opera is a form of theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another.
