You, therefore, Lord cardinal, in your high office as Our Vicar in Rome for spiritual matters, will, We are sure, exert yourself with the gentleness that is characteristic of you, but with equal firmness, to the end that the music executed in the churches and the chapels of the secular and regular clergy of this City may be in entire harmony with Our instructions. There is much to be corrected or removed in the chants of the mass, of the Litany of Loretto, of the Eucharistic hymn, but that which needs a thorough renewal is the singing of the Vespers of the feasts celebrated in the different churches and basilicas. The liturgical prescriptions of the Caeremoniale Episcoporum and the beautiful musical traditions of the classical Roman school are no longer to be found. For the devout psalmody of the clergy, in which the people also used to join, there have been substituted interminable musical compositions on the words of the psalms, all of them modeled on old theatrical works, and most of them of such meager artistic value that they would not be tolerated for a moment even in our second-rate concerts. It is certain that Christian piety and devotion are not promoted by them; the curiosity of some of the less intelligent is fed, but the majority, disgusted and scandalized, wonder how it is that such an abuse can still survive. We therefore wish the cause to be completely extirpated, and that the solemnity of Vespers should be celebrated according to the liturgical rules indicated by Us. The Patriarchal basilicas will lead the way by the example of solicitous care and enlightened zeal of the Lord cardinals who preside over them, and with these will vie especially the minor basilicas, and the collegiate and parochial churches, as well as the churches and chapels of the religious orders. And do you Lord cardinal, neither accept excuses nor concede delays. The difficulty is not diminished but rather augmented by postponement, and since the thing is to be done, let it be done immediately and resolutely. Let all have confidence in Us and in Our word, with which heavenly grace and blessing are united. At first the novelty will produce some wonder among individuals; here and there a leader or director of a choir may find himself somewhat unprepared; but little by little things will right themselves, and in the perfect harmony between the music with the liturgical rules and the nature of the psalmody all will discern a beauty and a goodness which have perhaps never been observed. The Vespers service will indeed be notably shortened.
