Jean-Baptiste Krumphultz (1750–1790) was a French composer and virtuoso harpsichordist, noted for his contributions to the development of keyboard music during the late 18th century. Primarily associated with the classical genre, Krumphultz's works are characterized by their intricate counterpoint and melodic sophistication. His notable compositions include a series of harpsichord sonatas, many of which demonstrate a blend of French and Italian stylistic elements, reflecting the transitional nature of music during his time. Among his most recognized works are the "Sonates pour clavecin," which showcase his technical prowess and innovative use of harmony. Krumphultz’s impact on music lies in his role as a bridge between the Baroque and Classical periods, influencing later composers in the development of keyboard techniques and the evolution of sonata form. Although not as widely known today, his contributions helped shape the landscape of 18th-century music, earning him a place in the history of keyboard repertoire. His works are still performed by harpsichordists and continue to be studied for their musical depth and historical significance.
