The Angelic Salutation, Hail Mary, or Ave Maria (Latin) is a traditional biblical Catholic prayer asking for the intercession of the Virgin Mary, the mother of Jesus. The Hail Mary is used within the Catholic Church, and it forms the basis of the Rosary. The prayer is also used by some Anglicans as well as by many other groups within the Western Catholic tradition of Christianity. A somewhat different form of the prayer is used in the Eastern Orthodox and Oriental Orthodox churches and other groups of Eastern Christianity. Some Protestant denominations, such as Lutherans, also make use of some form of the prayer. Most of the text of the Hail Mary can be found within the Gospel of Luke.

The prayer incorporates two passages from Saint Luke's Gospel: "Hail, full of grace, the Lord is with thee," and "Blessed art thou amongst women and blessed is the fruit of thy womb." In mid-13th-century Western Europe the prayer consisted only of these words with the single addition of the name "Mary" after the word "Hail", as is evident from the commentary of Saint Thomas Aquinas on the prayer.

Arvo Pärt (born 11 September 1935; Estonian pronunciation: [ˈɑrvo ˈpært]) is an Estonian classical composer and one of the most prominent living composers of sacred music. Since the late 1970s, Pärt has worked in a minimalist style that employs his self-invented compositional technique, tintinnabuli. His music also takes inspiration from Gregorian chant.

Pärt was born in Paide, Järva County, Estonia. A prolonged struggle with Soviet officials led him to emigrate with his wife and their two sons in 1980. He lived first in Vienna, where he took Austrian citizenship, and then re-located to Berlin. He returned to Estonia around the turn of the 21st century and now lives alternately in Berlin and in Tallinn.

Familiar works by Pärt are Cantus In Memoriam Benjamin Britten for string orchestra and bell (1977) and the string quintet "Fratres I" (1977, revised 1983), which he transcribed for string orchestra and percussion, the solo violin "Fratres II" and the cello ensemble "Fratres III" (both 1980).
