Bernard de Bury (c. 1720–1785) was a French composer, pianist, and music theorist, primarily known for his contributions to the development of keyboard music in the 18th century. He was associated with the transition from the Baroque style to the Classical era, particularly in the realm of harpsichord and fortepiano music. De Bury's notable works include his collection "Pièces de Clavecin" (1737), which showcases his skill in writing expressive and intricate keyboard pieces. His compositions often reflect the elegance and ornamentation characteristic of the French style, and he was known for his innovative use of harmony and melody. In addition to his work as a composer, de Bury played a significant role in music education and theory. He published various treatises, including "La Méthode de Musique" (1768), which contributed to the understanding of music notation and performance practices of his time. Though not as widely recognized today, Bernard de Bury's influence on keyboard music and his pedagogical contributions helped lay the groundwork for later composers, making him an important figure in the evolution of Western classical music.
