Hymns and other forms of religious music are often of traditional and unknown origin. Western musical notation was originally created to preserve the lines of Gregorian chant, which before its invention was taught as an oral tradition in monastic communities. Traditional songs such as Green grow the rushes, O present religious lore in a mnemonic form, as do Western Christmas carols and similar traditional songs.
