The Bells on Temple Square handbell choir is an official music organization of The Church of Jesus Christ of Latter-day Saints. It was formed in 2005 under the direction of the Mormon Tabernacle Choir. The group is a double handbell choir, performing with 27 to 35 ringers on 2 sets of Malmark handbells (one 7-octave set and one 6½ octave set) and 2 sets of Malmark handchimes (6 octaves each). The 12 octave 2 bells are Malmark aluminums. Each part is usually doubled (played by two ringers on separate sets), except octave 2.
