Hasse , Johann Adolf (called in Italy Il Sas-sone, the Saxon), a German composer, born at Bergedorf, near Hamburg, March 25, 1699, died in Venice, Dec. 23,1783. He was a pupil of Porpora and Scarlatti. His opera Sesostrate, produced at Naples in 1726, established his reputation; and after giving several other works to the Italian stage, the success of which was insured by the cooperation of his wife, the celebrated singer Faustina, he accepted the office of chapelmaster and composer to the elector of Saxony. In 1733 he was invited to London to compete with Handel, and brought out his Ar-taserse, in which Farinelli made his debut before an English audience. Although the opera was performed 40 nights, Hasse, disgusted with the virulence of the musical cabals, left London, and about 1740 established himself in Dresden. Upon the bombardment of that city in 1760 he lost all his musical manuscripts. He then went to Vienna, and the last years of his life were spent in Venice. Dr. Burney considered Hasse the most learned, natural, and elegant composer of his age.
His works, including all the libretti of Metastasio, were so numerous that it is said he often failed to recognize his own music.
