In 1722, after short stints as tenor with the Hamburg and Brunswick operas, Hasse traveled to Naples where he studied with Porpora and A. Scarlatti. Nine years later (1731) Hasse was appointed to the court of Poland and the electoral court of Saxony. Beginning in 1734 he served off and on as the director of the Dresden opera where his concert master was the violin virtuoso and proponent of the new Italian concerto style, Pisendel. From 1764- 1773 he lived in Vienna. Hasse composed operas, cantatas, Masses, oratorios, Psalms, and instrumental works (sonatas, concertos, and chamber music). Hasse is mentioned in a letter (1775) from Carl Philip Emanuel to Forkel as one whose works his father had especially valued in his later years.
