Born in Venice, Benedetto Marcello was a member of a noble family and his compositions are frequently referred to as Patrizio Veneto. Although he was a music student of Lotti and Francesco Gasparini, his father wanted Benedetto to devote himself to law.
Indeed, Benedetto combined a life in law and public service with one in music. In 1711 he was appointed member of the Council of Forty (in Venice's central government), and in 1730 he went to Pola as Provveditore (district governor).
Benedetto Marcello was the brother of Alessandro Marcello (1669 -1747), also a composer of some note.
The composer Joachim Raff wrote an opera entitled Benedetto Marcello, based loosely on the life of Marcello.
As a composer, Marcello was best known in his lifetime and is now still best remembered for his Estro poetico-armonico (Venice, 1724-1727), a musical setting for voices, figured bass (a continuo notation), and occasional soloist instruments of the first fifty Psalms, as paraphrased in Italian by his friend G. Giustiniani. They were much admired by Charles Avison, who with John Garth brought out an edition with English words (London, 1757).
The library of the Brussels Conservatoire possesses some interesting volumes of chamber-cantatas composed by Marcello for his mistress. Although Benedetto Marcello wrote an opera called La Fede riconosciuta and produced it in Vicenza in 1702, he had little sympathy with this form of composition, as evidenced in his writings (see below).
Benedetto Marcello's music is "characterized by imagination and a fine technique and includes both counterpoint and progressive, galant features" (Grove, 1994).
Marcello vented his opinions on the state of musical drama at the time in the satirical pamphlet Il teatro alla moda, published anonymously in Venice in 1720. This little work, which was frequently reprinted, is not only extremely amusing, but is most valuable as a contribution to the history of opera.
