Antonio Vivaldi (1678–1741) was an Italian Baroque composer, violin virtuoso, and Catholic priest, renowned for his innovative instrumental concertos and rich orchestration. Recognized as one of the greatest composers of his era, he helped shape the concerto form and expanded possibilities for violin technique and programmatic music. His most famous work, The Four Seasons, remains a staple of classical repertoire. A significant portion of his music, including concertos, sacred works, and over fifty operas, was composed for the talented girls of the Ospedale della Pietà in Venice. Though he enjoyed acclaim in his lifetime, Vivaldi died in poverty, but his music was rediscovered in the twentieth century and is now celebrated worldwide.
