Selections from Tra le Sollecitudini

Pope St. Pius X
, Motu Proprio, November 22, 1903

I. General Principles

1. Sacred music, being a complementary part of the solemn liturgy, participates in the general scope of the liturgy, which is the glory of God and the sanctification and edification of the faithful. It contributes to the decorum and the splendor of the ecclesiastical ceremonies, and since its principal office is to clothe with suitable melody the liturgical text proposed for the understanding of the faithful, its proper aim is to add greater efficacy to the text, in order that through it the faithful may be the more easily moved to devotion and better disposed for the reception of the fruits of grace belonging to the celebration of the most holy mysteries.

2. Sacred music should consequently possess, in the highest degree, the qualities proper to the liturgy, and in particular sanctity and goodness of form, which will spontaneously produce the final quality of universality.

It must be holy, and must, therefore, exclude all profanity not only in itself, but in the manner in which it is presented by those who execute it.

It must be true art, for otherwise it will be impossible for it to exercise on the minds of those who listen to it that efficacy which the Church aims at obtaining in admitting into her liturgy the art of musical sounds.

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.

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 sixteenth 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.

III. The Liturgical Text

7. The language proper to the Roman Church is Latin. Hence it is forbidden to sing anything whatever in the vernacular in solemn liturgical functions–much more to sing in the vernacular the variable or common parts of the Mass and Office.

9. The liturgical text must be sung as it is in the books, without alteration or inversion of the words, without undue repetition, without breaking syllables, and always in a manner intelligible to the faithful who listen.

IV. External Form of the Sacred Compositions

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.

V. The Singers

12. With the exception of the melodies proper to the celebrant the altar and to the ministers, which must be always sung in Gregorian Chant, and without accompaniment of the organ, all the rest of the liturgical chant belongs to the choir of levites, and, therefore, singers in the church, even when they are laymen, are really taking the place of the ecclesiastical choir. Hence the music rendered by them must, at least for the greater part, retain the character of choral music.

By this it is not to be understood that solos are entirely excluded. But solo singing should never predominate to such an extent as to have the greater part of the liturgical chant executed in that manner; the solo phrase should have the character or hint of a melodic projection, and be strictly bound up with the rest of the choral composition.

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.

14. Finally, only men of known piety and probity of life are to be admitted to form part of the choir of a church, and these men should by their modest and devout bearing during the liturgical functions show that they are worthy of the holy office they exercise. It will also be fitting that singers while singing in church wear the ecclesiastical habit and surplice, and that they be hidden behind gratings when the choir is excessively open to the public gaze.

IX. Conclusion

29. Finally, it is recommended to choirmasters, singers, members of the clergy, superiors of seminaries, ecclesiastical institutions, and religious communities, parish priests and rectors of churches, canons of collegiate churches and cathedrals, and, above all, to the diocesan ordinaries to favor with all zeal these prudent reforms, long desired and demanded with united voice by all; so that the authority of the Church, which herself has repeatedly proposed them, and now inculcates them, may not fall into contempt.
