The six Concerts op. VI for violin, strings and continuo by Antonio Vivaldi were published in Amsterdam by Roger in 1719. Although the contribution of Vivaldi was most likely modest - even to assume that the publishing occurred without his authorization - these six compositions mark a decisive step towards the definition of the classic Vivaldi Concerto, consisting of three movements and with the participation of a single Soloist. This critical edition - mainly based on the first printed edition and its following reprints - takes into consideration also all the printed sources related to each single concert of op. VI found in anthologies and the manuscript ones kept at the Wiesentheid and Dresda libraries.
