Overlapping choral antiphony and responsorial singing are principal types of African polyphony. Alternative terms for "Antiphonary" are "Antiphonal" or " Antiphony". In Western classical music, call and response is known as antiphony. Most are moderately syllabic, with simple recitations used for the verses, sung in antiphony. Incipient polyphony (previously primitive polyphony) includes antiphony and call and response, drones, and parallel intervals.
