For the first time, he SPO invites young singers to join the orchestra in Vivaldi’s well known Gloria. Vivaldi composed this Gloria in Venice, probably in 1715, for the choir of the Ospedale della Pietà, an orphanage for girls. Vivaldi, a priest, music teacher and virtuoso violinist, composed many sacred works for the Ospedale, where he spent most of his career, as well as hundreds of instrumental concertos to be played by the girls’ orchestra. This, his most famous choral piece, presents the traditional Gloria from the Latin Mass in twelve varied cantata-like sections.
