Pier Francesco Cavalli (1602–1676) was an Italian composer and a prominent figure in the development of opera during the Baroque period. He was born in Crema, Italy, and became a key innovator in the Venetian school of opera, significantly influencing the genre's evolution. Cavalli's music is characterized by its emotional depth and rich melodic lines, blending elements of drama and lyricism. His notable works include operas such as "La Calisto" (1651) and "L'Argia" (1655), which showcased his ability to combine traditional Venetian styles with more expressive, humanistic themes. "La Calisto," in particular, is recognized for its intricate character development and orchestration. Cavalli's impact on music extends beyond his compositions; he played a crucial role in the popularization of opera in Europe, paving the way for future composers. His approach to storytelling through music laid the groundwork for the operatic form, influencing contemporaries and later figures like Handel and Gluck. Cavalli's work is celebrated for its richness and complexity, making him a significant contributor to the history of Western classical music.
