Giuseppe Domenico Scarlatti (1685 –1757) was an Italian composer who spent much of his life in the service of the Portuguese and Spanish royal families. He is classified 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.
Harpsichord (Italian cembalo; French clavecin), stringed keyboard instrument in which the strings are plucked to produce sound. It was developed in Europe in the 14th or 15th century and was widely used from the 16th to the early 19th century, when it was superseded by the piano. In the 20th century the harpsichord was revived for performance of music of the 16th, 17th, and 18th centuries, as well as for new compositions.
