Even Catholic parishes today are not wanting for talent. But no serious singer or organist will get anywhere near the typical music program, at least if he wants to retain his self-respect.
The pastor of a parish will typically have no education in the chant or in music, and he will hire the first music director who walks through the door.
Thus the slogan should be reversed: Catholics taught the world what music is supposed to sound like, and, more importantly, what it is supposed to mean.
Inaudible prayers, particularly of the Canon, which at first don't seem to have anything to do with music, end up being a very important part of the aesthetic of the traditional structure of the Mass.
And this speaks to the larger problem that no one wants to talk about: the restoration of the Roman rite is a precondition for a long-term fix for the problem.
For two thousand years, the Church has guided the development of music, carefully legislating to fuse artistic talent and aesthetic beauty with the demands of the Faith.
It bothers me when I hear it in a car commercial or some such. But for the most part, it's better than seeing sacred music relegated to the scrap heap.
You can count on one hand the number of Novus Ordo churches in this country that feature a fully Catholic music program of any quality, consistent with the Roman rite tradition.
