Hymns

A hymn is a type of song, usually religious, specifically written for the purpose of adoration or prayer, and typically addressed to a deity or deities, or to a prominent figure or personification. The word hymn derives from Greek ὕμνος (hymnos), which means "a song of praise". 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. Later hymnody in the Western church introduced four-part vocal harmony as the norm, adopting major and minor keys, and came to be led by organ and choir.
