Most Church meetings will be enhanced by the singing of hymns. Hymn singing invites the Spirit of the Lord into a meeting; allows members to join together in unified expressions of prayer, praise, and thanksgiving; adds beauty and interest; and teaches the doctrines of the gospel. (For additional information, see Hymns, pp. 380-81.)
Priesthood leaders should encourage all members to participate actively in congregational singing.Latter-day Saints have a long tradition of choir singing. Choirs can contribute greatly to the beauty and spirituality of our Church meetings.
