Composer and keyboard player. He was in Rome by 1650, studied with Antonio Cesti and Loreto Vittori, and became organist of S. Maria Maggiore (around 1663), S. Maria in Aracoeli (1664 until his death), and the Oratory of SS. Crocifisso (1664-85); at some point around 1670 he entered the employ of Prince Giambattista Borghese as harpsichordist and music director. Famous in his time as an outstanding keyboard virtuoso, Pasquini frequently performed with Corelli; the two became members, along with Alessandro Scarlatti, of the Arcadian Academy in 1706. He was renowned as a teacher; his students included Francesco Gasparini, Georg Muffat, and possibly Domenico Scarlatti. He composed a considerable amount of vocal music (much of it lost), including about seventeen oratorios, fourteen operas, and over fifty cantatas, but his present reputation rests on his keyboard works, especially his suites and variations, most unpublished during his lifetime.
