(CRITICAL EDITIONS). 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.
