You say your pastor wants to maintain a singable repertoire of about 50 songs. I believe you are saying he wants this so that people are familiar with the songs and not so much because he is concerned about the expense of obtaining new musical scores.
The priest said this to me after a particular Sunday during Lent that the singing wasn’t so swell. He took the opportunity to wrongly berate me about the number of new songs that we learned each year and insinuated that the singing wasn’t as full as it could have been because some songs in the repertoire weren’t being selected enough. (One of my legitimate responses to him was that some Lenten songs are to be used only during Lent.) The pastoral associate set a limit for the music director to teach only 3-4 new assembly songs per year, which I was in compliance with except for one year when I accidentally taught 5 songs to the assembly. The song styles would vary between older hymns written with new lyrics to more modern yet totally accessible compositions of various musical styles. We taught all new songs very methodically so as to integrate them successfully into the singable repertoire. I think that the priest believed that there was a connection between loss of familiarity with music selected less frequently and the addition of new music to the repertoire.
We originally had a repertoire of 323 songs that was pared down to 140 songs. What hurt was that the pastoral associate selected a lot of hymns to discard, reasoning that the assembly did not like singing hymns very well and that they were Protestant in origin. (Among these were: “All Creatures of Our God and King”, “All Hail the Power of Jesus’ Name”, “Let All Mortal Flesh Keep Silence”, From All That Dwell Below the Skies", Hail Redeemer, King Divine", “I Sing the Mighty Power of God”, “On Jordan’s Bank” “To Jesus Christ, Our Sovereign King”, and others.) I tried to argue that the last reason was not legitimate in itself when the musical forms of those hymns have stood the test of time in terms of musical integrity and that the lyrics are in accord with Catholic teaching. It is my personal belief that the p.a. preferred the music they grew up with (post 1965 including the music of the St. Louis Jesuits and their contemporaries). Plus very few of the discarded hymns were of the category as described by mercygate as sappy victorian parlor hymns. mercygate is right about that too. As a current organist and choruster in a Presbyterian church (until a position opens up for a Director of Music at a local Catholic church), I just grin and bear it when those kind of hymns are selected for me to play. They are so drippy!
I understand the boredom factor. But keep in mind that musicians tend to have a much greater boredom threshold than other people in the congregation since they haven’t rehearsed a song 20 times before it was ever heard at Mass.
SMHW also has made an accurate observation. those of us who are musicians do tend to have a greater boredom factor and the first complaints about music getting old quickly tends to come from the choirs and the cantors.
We do have a lot of songs from the hymnal in our repertoire, but our director will spring a new one at the last minute. He seems to think everyone in choir and sight read. Not this girl, especially not the alto part. New songs are good, but people need time to learn them.
I have visited churches where new music is introduced almost weekly. Boy that’s a guarantee for failure! I have also been at a church where there are no hymnals and the music is printed in a program that is used weekly for 4 to 6 weeks at a time (with all the appropriate copy permissions). But you know, it works for them and they are thus able to stay more current than those with hymnals.
Trained and experienced in both classical music and classic rock, I have a rich background with both secular and religious music. There is one deficiency in my musical background and it is chant. I want more exposure to these forms since there does seem to be at least a minor trend to reintroduce and use that music. I am so glad that many of you have spoken highly of chant and sacred polyphony. It is encouraging.
Regarding shelf life to music, it is good for me to have fresh perspectives that I wouldn’t have considered otherwise. You all are wonderful! I will take solace in mercygate’s comment:
I think it’s like everything else. The good stuff will last; the junk will disappear.
