Domenico Scarlatti was an Italian composer born in 1685, known for his significant contributions to keyboard music. He spent much of his life in Portugal and Spain, where he composed over 550 keyboard sonatas, showcasing his innovative style and mastery of the harpsichord. Scarlatti's music is characterized by its lively rhythms, intricate melodies, and unique use of harmony. His sonatas often feature bold contrasts and are considered precursors to the later works of classical composers like Ludwig van Beethoven and Frédéric Chopin. Scarlatti's influence on keyboard music remains profound to this day.
