Bernardo Pasquini (7 December 1637 – 21 November 1710) was an Italian composer of operas, oratorios, cantatas and keyboard music. A renowned virtuoso keyboard player in his day, he was one of the most important Italian composers for harpsichord between Girolamo Frescobaldi and Domenico Scarlatti, having also made substantial contributions to the opera and oratorio.
Pasquini was born at Massa in Val di Nievole (today Massa e Cozzile), Grand Duchy of Tuscany. He was a pupil of Mariotto Bocciantini in Uzzano. Around 1650 he moved to Ferrara with his uncle Giovanni Pasquini. In 1654–55 he was organist of Accademia della Morte. Later he moved to Rome and in 1657 became organist of Santa Maria in Vallicella (Chiesa nuova). In November 1667 entered to the service of Prince Borghese. In February 1664 he was appointed organist of the Basilica di Santa Maria Maggiore and Santa Maria in Aracoeli. As a composer and keyboard player, he collaborated to the music performances patronised by most famous patrons in Rome, such as cardinals Flavio Chigi, Benedetto Pamphilj, Pietro Ottoboni, and Queen Christina of Sweden in whose honour his operas L'Alcasta (libretto by Giovanni Filippo Apolloni), and Il Lisimaco (libretto by Giacomo Sinibaldi) were performed respectively in 1673 and 1681.
Together with Arcangelo Corelli and Alessandro Scarlatti, in 1706 Pasquini became member of the Academy of Arcadia.
He composed numerous operas, all staged in Rome between 1672 and 1692, and partially replayed in several Italian theatres (Florence, Pisa, Naples, Ferrara, Perugia, Genoa, Rimini etc.).
