Giuseppe Domenico Scarlatti was born in 1685 in Naples, Italy.  Same year Bach was born!  And Handel!  He wrote operas, cantatas, symphonies, liturgical pieces, etc, and LOTS of keyboard music, primarily intended for harpsichord (or very early pianofortes).  When I say a lot, consider his keyboard sonatas:  he cranked out 555 of them.  Be amazed at Martha Argerich’s precision rendition of one of these works.
