This study score follows the very successful publications of the Urtext full score and performance material (BA 6994) and the piano reduction of all four concertos (BA 6994a). This critical edition of Vivaldi’s masterpiece is based on the Manchester manuscript source, which originates from Vivaldi’s circle, and represents an alternative (in many cases, more explicit) version of these famous concertos. The Manchester source has until now not been used as the primary source for a modern edition. - First study score to be based on the Manchester source - Critical scholarly edition - Details regarding the work's source history as well as comments on performance practice Content Concerto No. 1 Spring op. 8 RV 269 Concerto No. 2 Summer op. 8 RV 315o Concerto No. 3 Autumn op. 8 RV 293 Concerto No. 4 Winter op. 8 RV 297
