The music of Antonio Vivaldi is heard everywhere due to the tremendous success of his four concertos known as The Four Seasons. This popularity was not always the case. Like his contemporary J. S. Bach, his music lay largely unforgotten until in 1829 during the revival of interest in Bach largely inspired by Mendelssohn. It was discovered that Bach had based an organ piece on one of Vivaldi’s concertos. His music gradually became more well known but it was not until the 1930’s that he gained the recognition that he deserved. He produced a vast output – so many concertos that Stravinsky complained “The same concerto four hundred times”.
