The streamlined form and feeling of spaciousness in RV417’s outer movements is typical of Vivaldi’s mature style. The middle movement, in minuet rhythm and in binary form, is accompanied throughout by the continuo alone. To make the slow movement of a concerto indistinguishable from a slow movement in a sonata for the same instrument was an option frequently taken by Vivaldi in mid-career. In this intensely productive period, he often borrowed actual movements from sonatas for his concertos, and doubtless sometimes also vice versa.
