Yes, we are, and one of those reasons is to PRAISE God, for the gift of His Son, and His awesome Creation. There is a lot of good music out there, and I, for one, as a choir member, love to try out the new stuff, as well as 'oldies, but goodies'.
The Council of Trent reaffirmed traditional Christian teaching that the Mass is the same Sacrifice of Calvary offered in an unbloody manner. People forget what is going on there. The reverence is missing as people celebrate. MountainBunny said it right, “I’m Roman Catholic. If the Transubstantiation isn’t enough to hold your attention, I’m not sure what to tell you.”
Introducing new music is fine. Introducing a new song every week is over kill. I went to a church on Thanksgiving where the Music Director introduced the new song before Holy Mass and had a practice with the congregation. No prayertime in that church before Mass.
The music is not that important to those in the pew. Especially those who are trying to pray after communion. The happy praise music gets in the way.
Like liturgical committees, Choir Directors aren’t always making things better.
We have a parish that sings, because we don’t have a group of people doing it for us.
