1367. Not Appropriate to Set Obligatory Prayers to Music
"We have not come across any instructions which would prohibit the setting of the obligatory prayers to music. However, because of their special nature, we do not consider it appropriate to do so."
(From a letter of the Universal House of Justice to the National Spiritual Assembly of the United States, May 6, 1966)
