78 It would certainly be best if in diocesan Councils of Christian Art there were someone especially expert in the fields of religious music and chant who could carefully watch over what is being done in the diocese, inform the Ordinary about what has been done and what is going to be done, receive the Ordinary's commands and see that they are obeyed. If in any diocese there is one of these associations, which have been wisely instituted to foster sacred music and have been greatly praised and commended by the Sovereign Pontiffs, the Ordinary in his prudence may employ this association in the task of fulfilling responsibility.
