Antonio Lucio Vivaldi composed this Gloria in Venice, probably in 1715, for the choir of the Ospedale della Pietà, an orphanage for girls (or more probably a home, generously endowed by the girls' "anonymous" fathers, for the illegitimate daughters of Venetian noblemen and their mistresses). The Ospedale prided itself on the quality of its musical education and the excellence of its choir and orchestra. 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.
 
For two centuries after his death, the Gloria lay undiscovered until the late 1920s, when it was found buried among a pile of forgotten manuscripts. However, it was not performed until September 1939 in Siena in an edition by the composer Alfredo Casella. This was by no means an authentic edition (he described it as an "elaborazione"), as he embellished the original orchestration of trumpet, oboe, strings, and continuo, while reducing the role of the continuo, and cut sections from three movements. It was not until 1957 that the now familiar original version was published and given its first performance at the First Festival of Baroque Choral Music at Brooklyn College, New York.

The 10.10 Ensemble presents a performance of the original version, with vocal solos being shared between ensemble members.
