An impresario (from the Italian impresa, "an enterprise or undertaking") is a person who organizes and often finances concerts, plays, or operas, performing a role similar to that of an artist manager or a film or television producer.
The term originated in the social and economic world of Italian opera, in which from the mid-18th century to the 1830s, the impresario was the key figure in the organization of a lyric season. The owners of the theatre, usually noble amateurs, charged the impresario with hiring a composer (until the 1850s operas were expected to be new) and the orchestra, singers, costumes and sets, all while assuming considerable financial risk. In 1786 Mozart satirized the stress and emotional mayhem in a single-act farce Der Schauspieldirektor (The Impresario). Antonio Vivaldi was unusual in acting as both impresario and composer; in 1714 he managed seasons at Teatro San Angelo in Venice, where his opera Orlando finto pazzo was followed by numerous others.
Alessandro Lanari (1787–1852), who began as the owner of a shop that produced costumes, eliminated the middleman in a series of successful seasons he produced for the Teatro La Pergola, in Florence, which presented the premieres of the first version of Verdi's Macbeth, two of Bellini's operas and five of Donizetti's, including Lucia di Lammermoor. Domenico Barbaia (1778–1841) began as a café waiter and made a fortune at La Scala, in Milan, where he was also in charge of the gambling operation and introduced roulette.
Duchess Elisabeth Sophie of Mecklenburg was a harpsichordist who also presided over seventeenth-century North German court music as an impresario.
