Philippe de Vitry

Philippe de Vitry was a 14th-century French composer, music theorist, and poet, best known for his significant influence on medieval music. He is credited with developing the concept of "ars nova," which introduced new rhythmic styles and notational systems, allowing for greater complexity in music. His work marked a transition from the prior "ars antiqua" style, emphasizing more varied and expressive compositions. Vitry's ideas laid the groundwork for the evolution of Western music, influencing subsequent generations of composers and shaping the transition to the Renaissance music style.
