Antonio Vivaldi was a Baroque composer from Venice, Italy, born on March 4, 1678, and died on July 28, 1741. His major product was instrumental music. He is particularly known for his concertos, especially his violin concertos, which are some of the most well-known and frequently performed works of the Baroque period. Vivaldi's most famous set of concertos is his Four Seasons, which consists of four violin concertos, each representing a different season of the year. He also composed a large number of other concertos, including concertos for other instruments such as the flute, oboe, and bassoon. In addition to his concertos, Vivaldi also composed operas, chamber music, and sacred choral music. However, his instrumental music, particularly his concertos, remains his most well-known and influential contribution to music history.
