Lodovico Grossi da Viadana (c.1560 – 1627) was an Italian composer, teacher, and Franciscan Friar. He is known for the important contribution he made to the development of Baroque music, being one of the first people to use figured bass as a means of notating a basso continuo line. From 1594 onwards he was choirmaster at various Italian cathedrals, when his O Sacrum Convivium was most probably written. It is an arrangement of the ancient Christian prayer for TTBB Male Voice Chorus, and is a perfect anthem for any Eucharist service.
