As published, Vivaldi's Opus 10 is a straightforward collection of concertos for flute and string orchestra. Most works which originally called for obbligato flutes seem to have originated during the early 1720s, perhaps reflecting opportunities that Vivaldi encountered in Rome, where he stayed intermittently between c. 1719 and 1724. Although the transverse flute was then little known in Italy, the availability of an excellent player is was essential for the execution of several of his works for it.
