Angelo Berardi was an Italian music theorist and composer. Born in Sant'Agata Feltria, "Sant'Agata, Tuscany", or some other Sant'Agata yet to be identified, he received early education at Forlì under Giovanni Vincenzo Sarti (1600–1655). From 1662 he was maestro di cappella in Montefiascone. He studied under Marco Scacchi at Gallese at some time between 1650 and Scacchi's death in 1662; he included two motets by Scacchi in Book 1 of his Documenti armonici of 1687, and also cites him frequently.
