Giuseppe Domenico Scarlatti, also known as Domingo or Doménico Scarlatti, was an Italian composer. He is classified primarily as a Baroque composer chronologically, although his music was influential in the development of the Classical style. Like his renowned father Alessandro Scarlatti, he composed in a variety of musical forms, although today he is known mainly for his 555 keyboard sonatas. He spent much of his life in the service of the Portuguese and Spanish royal families.
