Why did Antonio Vivaldi’s career decline during the 1730s?

During the 1730s, the career of the Italian composer Antonio Vivaldi experienced a gradual decline primarily because his music fell out of fashion. Contemporary accounts, such as those from the French traveler Charles de Brosses in 1739, noted with regret that Vivaldi’s once-celebrated musical style was no longer in vogue.1

Additionally, Vivaldi’s efforts as an impresario during this period were increasingly marked by failure. While he had previously enjoyed great success and entrepreneurial opportunities as a freelance composer and opera producer, these later ventures did not achieve the same level of prosperity. By the end of the decade, his financial situation had deteriorated significantly; he eventually traveled to Vienna in 1740, where he died in 1741 in what is believed to have been considerable poverty.1
