Pascal Collasse (c. 1640–1710) was a French composer and musician primarily associated with the Baroque genre. He is best known for his contributions to the development of French opera and instrumental music during the late 17th century. Collasse served as a composer for the court of Louis XIV and was influential in the establishment of French opera, particularly with his work "Les Fêtes de l'Amour et de Bacchus" (1685), which showcased his ability to blend lyrical melodies with rich orchestration. His notable works also include various ballets and cantatas, reflecting the stylistic preferences of the time while also incorporating elements of Italian music. Collasse’s impact on music lies in his role in shaping the French Baroque style and influencing subsequent generations of composers, particularly in the realm of theatrical music. His works are often studied for their melodic charm and structural elegance, contributing to the evolution of French music in the Baroque era.
