The most famous of three settings of the Gloria text by Vivaldi, this one (RV 589) most likely dates from about the same time as its predecessor, during the composer's tenure at the Ospedale della Pietà convent in Venice (1713-40). It's also notable for the borrowing of the "Cum Sancto Spiritu" chorus in the setting by Vivaldi's fellow Venetian - Giovanni Maria Ruggieri. This new vocal score is a digitally enhanced reprint of the one originally prepared by the American musicologist Clayton Westermann in 1967 and includes the editor's helpful preface. Now available in an easy-to-read A4 format, with measure numbers and an improved layout, at an affordable price.
