This classical piece is playing at Miss Patty’s as Lorelai and Rory walk past, the accompanying music to her dance class, who are rehearsing for the Autumn Festival with a Thanksgiving-inspired dance. It is part of Concerto No. 3 in F Major, the “Autumn” section of The Four Seasons violin concerti by Italian composer Antonio Vivaldi. It was first published in 1725, with each concerto accompanied by a sonnet about the season. The “Autumn” one begins, Celebrate the peasant with songs and dances. The music is perfect for the Autumn Festival, and to accompany dancers in a small town.
