Pergolesi, Or Pergolese, Giovanni Battista, an Italian composer, born in Jesi, Jan. 3, 1710, died at Torre del Greco, near Naples, March 16,1736. He entered the Neapolitan conservatory dei poveri in Gesu Cristo, but left it at the age of 14, and received lessons in vocal composition from Vinci and Hasse. At 20 years of age he procured an engagement at the teatro nuovo, Naples, for which he wrote comic intermezzos, including the Serva padro-na, subsequently produced with great enthusiasm at Paris. Iu 1734 he left Naples to become chapelmaster in Loreto, and in 1735 went to Rome, where he brought out his opera of Olimpiade, which was coldly received, notwithstanding it was highly commended by contemporary musicians. He renounced the drama, and returning to Loreto applied himself wholly to sacred compositions, which were better appreciated; and few works of their class have been more admired than his mass in D, containing the celebrated Gloria in Ex-eelsis, and his Dixit Dominus and Laudate. Shortly before his death, his health failing rapidly, he removed to Torre del Greco, near the foot of Mt. Vesuvius. Here during his last illness he composed his cantata of Orfeo ed Euridice, his Salve Pegina, and his celebrated Staoat Mater.
