Tra le sollecitudini

Tra le sollecitudini (Italian for "among the concerns") was a motu proprio issued 22 November 1903 by Pope Pius X that detailed regulations for the performance of music in the Catholic Church. The title is taken from the opening phrase of the document (which was written and officially published in Italian). It begins: "Among the concerns of the pastoral office, ... a leading one is without question that of maintaining and promoting the decorum of the House of God in which the august mysteries of religion are celebrated...." The regulations pointed toward more traditional music and critiqued the turn toward modern, orchestral productions at Mass.
