Domenico Scarlatti was an Italian composer from the Baroque period best known for composing the 555 keyboard sonatas. Born to an esteemed musician father Alessandro Scarlatti, Domenico became interested in music early on. After taking early musical lessons from his father, he went on receiving training under several musicians and by the age of 15, he began working at chapels as an organist. After working at a few chapels, he was appointed as a teacher to the Portuguese princess Maria Magdalen Barbara. When she became the queen of Spain, Domenico was hired to be in the full-time service of the court. As a musician, Domenico composed many operas in the beginning along with vocal music. However, when he realized his lack of expertise in these, he focused solely on harpsichord compositions. He thus embarked on a musical journey that established him as one of the most imaginative and well-known musicians of 17th century Europe. He is best known for 555 keyboard sonatas, which were mostly composed for harpsichord. Owing to his allegiance to the royal court, he could not publish much of his music when he was alive, but posthumously he got regarded as a master musician.
