La stravaganza, Op. 4, is a set of concertos written by Antonio Vivaldi in 1712–1713. The set was first published in 1716 in Amsterdam and was dedicated to Venetian nobleman Vettor Delfino, who had been a violin student of Vivaldi's.
RV 298, the G Major Concerto, is the final piece from the publication. It remains one of Vivaldi's most popular violin solos.
