Nothing should have place, therefore, in the temple calculated to disturb or even merely to diminish the piety and devotion of the faithful, nothing that may give reasonable cause for disgust or scandal, nothing, above all, which directly offends the decorum and sanctity of the sacred functions and is thus unworthy of the House of Prayer and of the Majesty of God. We do not touch separately on the abuses in this matter which may arise. Today Our attention is directed to one of the most common of them, one of the most difficult to eradicate, and the existence of which is sometimes to be deplored in places where everything else is deserving of the highest praise-the beauty and sumptuousness of the temple, the splendor and the accurate performance of the ceremonies, the attendance of the clergy, the gravity and piety of the officiating ministers. Such is the abuse affecting sacred chant and music.

And indeed, whether it is owing to the very nature of this art, fluctuating and variable as it is in itself, or to the succeeding changes in tastes and habits with the course of time, or to the fatal influence exercised on sacred art by profane and theatrical art, or to the pleasure that music directly produces, and that is not always easily contained within the right limits, or finally to the many prejudices on the matter, so lightly introduced and so tenaciously maintained even among responsible and pious persons, the fact remains that there is a general tendency to deviate from the right rule, prescribed by the end for which art is admitted to the service of public worship and which is set forth very clearly in the ecclesiastical Canons, in the Ordinances of the General and Provincial Councils, in the prescriptions which have at various times emanated from the Sacred Roman Congregations, and from Our Predecessors the Sovereign Pontiffs.

, a leading [concern] is without question that of maintaining and promoting the decorum of the House of God in which the august mysteries of religion are celebrated, and where the Christian people assemble to receive the grace of the Sacraments, to assist at the Holy Sacrifice of the Altar, to adore the most august Sacrament of the Lord's Body and to unite in the common prayer of the Church in the public and solemn liturgical offices. Nothing should have place, therefore, in the temple calculated to disturb or even merely to diminish the piety and devotion of the faithful, nothing that may give reasonable cause for disgust or scandal, nothing, above all, which directly offends the decorum and sanctity of the sacred functions and is thus unworthy of the House of Prayer and of the Majesty of God

Here are principles which can govern us, as musicians, as laymen.

But it must, at the same time, be universal in the sense that while every nation is permitted to admit into its ecclesiastical compositions those special forms which may be said to constitute its native music, still these forms must be subordinated in such a manner to the general characteristics of sacred music that nobody of any nation may receive an impression other than good on hearing them.

Part II. The Different Kinds of Sacred Music

3. These qualities are to be found, in the highest degree, in Gregorian Chant, which is, consequently the Chant proper to the Roman Church, the only chant she has inherited from the ancient fathers, which she has jealously guarded for centuries in her liturgical codices, which she directly proposes to the faithful as her own, which she prescribes exclusively for some parts of the liturgy, and which the most recent studies have so happily restored to their integrity and purity.

On these grounds Gregorian Chant has always been regarded as the supreme model for sacred music, so that it is fully legitimate to lay down the following rule: the more closely a composition for church approaches in its movement, inspiration and savor the Gregorian form, the more sacred and liturgical it becomes; and the more out of harmony it is with that supreme model, the less worthy it is of the temple.

The ancient traditional Gregorian Chant must, therefore, in a large measure be restored to the functions of public worship, and the fact must be accepted by all that an ecclesiastical function loses none of its solemnity when accompanied by this music alone.

Special efforts are to be made to restore the use of the Gregorian Chant by the people, so that the faithful may again take a more active part in the ecclesiastical offices, as was the case in ancient times.

4. The above-mentioned qualities are also possessed in an excellent degree by Classic Polyphony, especially of the Roman School, which reached its greatest perfection in the fifteenth century, owing to the works of Pierluigi da Palestrina, and continued subsequently to produce compositions of excellent quality from a liturgical and musical standpoint. Classic Polyphony agrees admirably with Gregorian Chant, the supreme model of all sacred music, and hence it has been found worthy of a place side by side with Gregorian Chant, in the more solemn functions of the Church, such as those of the Pontifical Chapel. This, too, must therefore be restored largely in ecclesiastical functions, especially in the more important basilicas, in cathedrals, and in the churches and chapels of seminaries and other ecclesiastical institutions in which the necessary means are usually not lacking.

5. The Church has always recognized and favored the progress of the arts, admitting to the service of religion everything good and beautiful discovered by genius in the course of ages-always, however, with due regard to the liturgical laws. Consequently modern music is also admitted to the Church, since it, too, furnishes compositions of such excellence, sobriety and gravity, that they are in no way unworthy of the liturgical functions.

Still, since modern music has risen mainly to serve profane uses, greater care must be taken with regard to it, in order that the musical compositions of modern style which are admitted in the Church may contain nothing profane, be free from reminiscences of motifs adopted in the theaters, and be not fashioned even in their external forms after the manner of profane pieces.

6. Among the different kinds of modern music, that which appears less suitable for accompanying the functions of public worship is the theatrical style, which was in the greatest vogue, especially in Italy, during the last century. This of its very nature is diametrically opposed to Gregorian Chant and classic polyphony, and therefore to the most important law of all good sacred music. Besides the intrinsic structure, the rhythm and what is known as the conventionalism of this style adapt themselves but badly to the requirements of true liturgical music.

it is permissible, according to the custom of the Roman Church, to sing a motet to the Blessed Sacrament after the Benedictus in a solemn Mass.

Part IV. External Form of Sacred Composition


10. The different parts of the mass and the Office must retain, even musically, that particular concept and form which ecclesiastical tradition has assigned to them, and which is admirably brought out by Gregorian Chant. The method of composing an introit, a gradual, an antiphon, a psalm, a hymn, a Gloria in excelsis, etc., must therefore be distinct from one another.

11. In particular the following rules are to be observed:

The Kyrie, Gloria, Credo, etc., of the Mass must preserve the unity of composition proper to the text. It is not lawful, therefore, to compose them in separate movements, in such a way that each of these movements form a complete composition in itself, and be capable of being detached from the rest and substituted by another.

In the office of Vespers it should be the rule to follow the Caeremoniale Episcoporum, which prescribes Gregorian Chant for the psalmody and permits figured music for the versicles of the Gloria Patri and the hymn.

It will nevertheless be lawful on greater solemnities to alternate the Gregorian Chant of the choir with the so called falsi-bordoni or with verses similarly composed in a proper manner.

It is also permissible occasionally to render single psalms in their entirety in music, provided the form proper to psalmody be preserved in such compositions; that is to say, provided the singers seem to be psalmodising among themselves, either with new motifs or with those taken from Gregorian Chant or based upon it.

The psalms known as di concerto are therefore forever excluded and prohibited.

In the hymns of the Church the traditional form of the hymn is preserved. It is not lawful, therefore, to compose, for instance, a Tantum ergo in such wise that the first strophe presents a romanza, a cavatina, an adagio and the Genitori an allegro.

The antiphons of the Vespers must be as a rule rendered with the Gregorian melody proper to each. Should they, however, in some special case be sung in figured music, they must never have either the form of a concert melody or the fullness of a motet or a cantata.

13. On the same principle it follows that singers in church have a real liturgical office, and that therefore women, being incapable of exercising such office, cannot be admitted to form part of the choir. Whenever, then, it is desired to employ the acute voices of sopranos and contraltos, these parts must be taken by boys, according to the most ancient usage of the Church.
