A cappella, ˌɑː_kəˈpɛlə, also UKˌæ_-, a kkapˈpɛlla) music is a performance by a singer or a singing group without instrumental accompaniment, or a piece intended to be performed in this fashion. The term a cappella was originally intended to differentiate between Renaissance polyphony and Baroque concertato musical styles. In the 19th century, a renewed interest in Renaissance polyphony, coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists, led to the term coming to mean unaccompanied vocal music.
Mary, mother of JesusMary was a first-century Judean woman of Nazareth, the wife of Joseph and the mother of Jesus. She is a central figure of Christianity, venerated under various titles such as virgin or queen, many of them mentioned in the Litany of Loreto. The Eastern and Oriental Orthodox, Church of the East, Catholic, Anglican, and Lutheran churches believe that Mary, as mother of Jesus, is the Mother of God. Other Protestant views on Mary vary, with some holding her to have considerably lesser status.
TheotokosTheotokos (Greek: Θεοτόκος) is a title of Mary, mother of Jesus, used especially in Eastern Christianity. The usual Latin translations are Dei Genitrix or Deipara (approximately "parent (fem.) of God"). Familiar English translations are "Mother of God" or "God-bearer" – but these both have different literal equivalents in Greek, Μήτηρ Θεοῦ and Θεοφόρος ("Who gave birth to one who was God", "Whose child was God", respectively).
