This piece is a joyous and exuberant chorus from Antonio Vivaldi's Domine ad adjuvandum me festina, a polychoral motet based on Psalm 69. Originally scored for two choirs, this edition by Patrick Liebergen is a shortenedversion of the first of three movements, with a keyboard reduction of the full orchestral score and an optional trumpet part provided as the accompaniment. Outstanding choral masterwork.
