Cantata: an unstaged secular or sacred composition, with several movements, for single voice or voices (alternating aria, duet, recitative, full chorus, etc.), normally accompanied by instruments. The vocal equivalent of sonata.
Mass: the sacred liturgy first of the Roman Catholic church, and later of the Lutheran and Anglican rites, in which the Last Supper of Jesus, or Holy Eucharist, is celebrated. Derived from the priest's last words "Ite missa est" (the table is concluded).
Oratorio: an unstaged drama or narrative of Biblical events composed for voices (alternating aria, narrator, recitative, full chorus, etc.) and accompanied by instruments.
