Assigned Readings To Masses

[quia_pulvis]

This has been bothering me and I want to be clear on this.

I'm only noticing this at a Sunday mass so my scenario is based upon that. We have 3 assigned readings: Prophet, Apostle, and Gospel. Those are all good. My problem is the Psalm. The choir/band rarely does the one that is prescribed for that day. It seems they go through a rotation of psalms they know and when they come across a day they know the music to the psalm they will play it. This bothers me but I may be wrong in my thinking. If the psalm for that day is 60:1-6 (random sorry), then are we supposed to be reciting that psalm whether we know the music or not?

From the GIRM

[61]
The responsorial Psalm should correspond to each reading and should, as a rule, be taken from the Lectionary.

It is preferable that the responsorial Psalm be sung, at least as far as the people's response is concerned. Hence, the psalmist, or the cantor of the Psalm, sings the verses of the Psalm from the ambo or another suitable place. The entire congregation remains seated and listens but, as a rule, takes part by singing the response, except when the Psalm is sung straight through without a response. In order, however, that the people may be able to sing the Psalm response more readily, texts of some responses and Psalms have been chosen for the various seasons of the year or for the various categories of Saints. These may be used in place of the text corresponding to the reading whenever the Psalm is sung. If the Psalm cannot be sung, then it should be recited in such a way that it is particularly suited to fostering meditation on the word of God.

In the dioceses of the United States of America, the following may also be sung in place of the Psalm assigned in the Lectionary for Mass: either the proper or seasonal antiphon and Psalm from the Lectionary, as found either in the Roman Gradual or Simple Gradual or in another musical setting; or an antiphon and Psalm from another collection of the psalms and antiphons, including psalms arranged in metrical form, providing that they have been approved by the United States Conference of Catholic Bishops or the Diocesan Bishop. Songs or hymns may not be used in place of the responsorial Psalm.

That may have changed since the most recent changes in the liturgy
