The memorable tunes and infectious optimism of Vivaldi's Gloria have made it one of the most popular choral works in the repertoire. For this edition, the distinguished Vivaldi scholar Paul Everett has returned to the autograph manuscript as the most authoritative source. Both full and vocal scores make clear distinction between original and editorial markings, and information on performance practice is relevant without being prescriptive. The vocal score includes an orchestral reduction for rehearsal purposes, and the full score is supplemented by a comprehensive critical commentary and continuo realization. It also includes a unique transcription of Ruggieri's 'Cum Sancto Spiritu', on which Vivaldi based his own setting.
