In the seventeenth century, the Ospedale della Pietà in Venice took in young orphan girls who received advanced musical instruction. The concerts given there attracted visitors from all over the world, curious to hear these divine voices which remained invisible, since the girls performed hidden behind the grilles of the chapel gallery. Vivaldi became Maestro de' Concerti of the Pietà in 1714, and it was his pupils who performed his famous Nisi Dominus. Today they are succeeded by the mezzo-soprano Eva Zaïcik, who brings out the full poignancy of the aria 'Cum dederit'. Another motet by Vivaldi, Invicti bellate, also composed for the Pietà, features in this program planned and conducted by Vincent Dumestre. He invites us on a musical journey centered on the figure of woman and on divine praise, with composers awaiting discovery such as Serafino Razzi (1534-1619) and Soto de Langa (1531-1611).
