As regards music, let the clear and guiding norms of the Apostolic See be scrupulously observed.
Gregorian chant, which the Roman Church considers her own as handed down from antiquity and kept under her close tutelage,
is proposed to the faithful as belonging to them also. In certain parts of the liturgy the Church definitely prescribes it;
it makes the celebration of the sacred mysteries not only more dignified and solemn but helps very much to increase the faith
and devotion of the congregation. For this reason, Our predecessors of immortal memory, Pius X and Pius XI, decree— and We are happy to confirm with Our authority the norms laid down by them—that in seminaries and religious institutes, Gregorian chant be diligently and zealously promoted,
and moreover that the old Scholae Cantorum be restored, at least in the principal churches. This has already been done with
happy results in not a few places.
192. Besides, "so that the faithful take a more active part in divine worship, let Gregorian
chant be restored to popular use in the parts proper to the people. Indeed it is very necessary that the faithful attend the
sacred ceremonies not as if they were outsiders or mute onlookers, but let them fully appreciate the beauty of the liturgy
and take part in the sacred ceremonies, alternating their voices with the priest and the choir, according to the prescribed
norms. If, please God, this is done, it will not happen that the congregation hardly ever or only in a low murmur answer the
prayers in Latin or in the vernacular." A congregation that is devoutly present at the sacrifice, in which our Savior together
with His children redeemed with His sacred blood sings the nuptial hymn of His immense love, cannot keep silent, for "song
befits the lover" and, as the ancient saying has it, "he who sings well prays twice." Thus the Church militant, faithful as
well as clergy, joins in the hymns of the Church triumphant and with the choirs of angels, and, all together, sing a wondrous
and eternal hymn of praise to the most Holy Trinity in keeping with words of the preface, "with whom our voices, too, thou
wouldst bid to be admitted."
193. It cannot be said that modem music and singing should be entirely excluded from Catholic
worship. For, if they are not profane nor unbecoming to the sacredness of the place and function, and do not spring from a
desire of achieving extraordinary and unusual effects, then our churches must admit them since they can contribute in no small
way to the splendor of the sacred ceremonies, can lift the mind to higher things and foster true devotion of soul.
194. We also exhort you, Venerable Brethren, to promote with care congregational singing, and
to see to its accurate execution with all due dignity, since it easily stirs up and arouses the faith and piety of large gatherings
of the faithful. Let the full harmonious singing of our people rise to heaven like the bursting of a thunderous sea and let
them testify by the melody of their song to the unity of their hearts and minds, as becomes brothers and the children of the
