Who is Canticle?
In the context of Christian liturgy, a canticle (from the Latin canticulum, a diminutive of canticum, "song") is a psalm-like song with biblical lyrics taken from elsewhere than the Book of Psalms, but included in psalters and books such as the breviary. Of special importance to the Divine Office are three New Testament Canticles that are the climaxes of the Offices of Lauds, Vespers and Compline; these are respectively Benedictus (Luke 1:68-79), Magnificat (Luke 1:46-55) and Nunc dimittis (Luke 2:29-32). There are also a number of Canticles taken from the Old Testament.
