The following is a video that I created for my parish answering the question: How do we select music for Mass?
First, we look at the quote from the General Instruction of the Roman Missal:
In the Dioceses of the United States of America, there are four options for the Entrance Chant: (1) the antiphon from the Missal or the antiphon with its Psalm from the Graduale Romanum, as set to music there or in another setting; (2) the antiphon and Psalm of the Graduale Simplex for the liturgical time; (3) a chant from another collection of Psalms and antiphons, approved by the Conference of Bishops or the Diocesan Bishop, including Psalms arranged in responsorial or metrical forms; (4) another liturgical chant that is suited to the sacred action, the day, or the time of year, similarly approved by the Conference of Bishops or the Diocesan Bishop.

In the video above, I break open the 4th option given above, and how we prayerfully and strategically select music based on the “sacred action, the day, or the time of year”.
