On today's date in 1757, the Italian composer and harpsichordist Domenico Scarlatti died in Madrid. He was 71 years old, and for the last 38 years of his life had been employed at the court of Princess Maria Barbara, first in her native Portugal, and then, when the Princess married the heir to the Spanish throne, in Madrid. Although Domenico could very well have stayed in Italy and become a famous opera composer like his father, Alessandro Scarlatti, Domenico spent the better part of his life composing over 600 virtuoso sonatas for Maria Barbara. Only a handful of these were published during his lifetime. In the 19th century, Liszt and Brahms took the trouble to hunt down additional Scarlatti sonatas in manuscript, but the bulk of them remained unpublished and unknown until a complete edition was published in the 20th century. While not coming anywhere close to matching Scarlatti's output, one 20th century American composer, the Philadelphia-born Vincent Persichetti, composed ten harpsichord sonatas of his own. Like Scarlartti, Persichetti was a virtuoso keyboard performer, and wrote showcase pieces for the piano and organ in addition to the harpsichord. The growing number of modern-day harpsichordists has meant that in addition to the wealth of old music for the instrument, an increasing number of contemporary composers have followed Persichetti's example, and are writing new works for this old instrument.
