Ben: what a tribute to one of our best composers! I developed an appreciation for Vivaldi a number of years ago (almost 20, to be exact) when our church choir presented his `Gloria' at Christmas, some of my now favorite Christmas music. Vivaldi's music is more easily recognized than other composers' because he employed the same musical techniques in most of his pieces.
You are so right that `Spring' is most fitting to be enjoyed while gardening this time of year. I love to have classical music playing on the radio or CD player when I'm outdoors gardening.
