Music and accompaniment

In ancient and medieval times, string instruments such as the harp, lyre and lute were used with psalms and hymns.

Since there is a lack of musical notation in early writings, the actual musical forms in the early church can only be surmised. During the Middle Ages a rich hymnody developed in the form of Gregorian chant or plainsong. This type was sung in unison, in one of eight church modes, and most often by monastic choirs. While they were written originally in Latin, many have been translated; a familiar example is the 4th century Of the Father's Heart Begotten sung to the 11th century plainsong Divinum Mysterium.
