The term 'Song of Joy' can be described by three different words: PAEAN (5 letters), HYMN (4 letters), and CAROL (5 letters). A PAEAN is a song of joy or triumph, often in honor of a deity. A HYMN is a religious song of praise, usually addressed to God or a saint. A CAROL is a festive song, typically of a religious nature, sung at Christmas or other special occasions. All three words refer to a joyful song, often with spiritual or religious connotations.
