No.
Our parish is wealthy and large–over 7000 people. But in spite of the population and money, there are no musicians with the knowledge and ability to be able to sing Gregorian chant, and there are absolutely no musicians who have the knowledge and ability to TEACH chant.
I realize that this is quite a sweeping statement, but I believe it to be true. I know the musicians in our parish because I play piano, and my statement assessing the ability of our musicians to do chant is true. There may be musicians who are hiding their lamps under a bushel and refusing to “come out” and get involved with the Masses. But that doesn’t help the parish to add Gregorian chant to the Mass.
We have a “Music Director” but the gentlemen is not versatile. He doesn’t work with any of the choirs (traditional, children’s, or contemporary) and he seems to know nothing about choral or solo literature. He’s learning to accompany cantors and congregation on the organ, and he is learning to play the piano.
Most of the cantors in our parish do a very poor job singing the simple chant in the Responsorial Psalm, and I frankly wish that the Liturgy Director would find a Psalter that contains more melodious psalms so that the Psalms would be less grating to listen to.

I think that the current Psalter frightens potential cantors away, as there are no melodies and the chants are extremely ugly, like listening to looooong rap.
For those who long for Gregorian chant in our city, the Oratory does daily Latin Mass and several Latin Masses on the weekend, and these include the Gregorian chant and polyphony. So anyone who wants it can hear it only a mile away from our parish. Perhaps that’s another reason why none of the parishes in our city are rushing to add Gregorian chant and ancient polyphony to the Mass–it’s available elsewhere. Any musicians who want to sing chant can attend this parish–it’s a real parish–and sing the ancient music of the Church.
There seems to be a great deal of resistance in our city’s parishes to ancient music in the Mass. People here, and that includes the teenagers and children, really seem to like the contemporary music (I say “contemporary” tongue in cheek, as much of it is almost 50 years old). This could be because our city is very close (driving distance) to Willowcreek and some of the best live contemporary Christian music in the United States.
It could also be that because there are quite a few converts from evangelicalism in our parishes, there is resistance to chant. Yes, some converts like it, but most, and I consider myself in that number, prefer traditional hymns in English, and some CCM. I honestly don’t like chant at all, and I’ve given it several good, honest attempts, listening to CDs. I know, it’s not about my preferences. But since the GIRM allows for other kinds of music, I am not in the wrong to seek out parishes that feature music that I like. At this point, it’s still OK according to the rubrics for Masses to include four hymns in English (or whatever the language is) and the responses in English (vernacular) in a traditional/contemporary style.
So mainly because of the lack of talent/ability of the musicians, I think it’s unlikely that we will see much Gregorian chant in any of the parishes other than at the Oratory. If the seminaries begin graduating priests who are also trained musicians, that could make a difference. as they might be able to train the musicians in the parishes. Of course, whether or not the congregations would tolerate it is another question. I honestly think that it would not go over well, and that many Catholics would head for parishes that feature hymns in English or Spanish rather than Gregorian chant. It would have to be introduced very gradually, with just a smidgeon in the Mass at first.
BTW, in case you’re wondering, our bishop has often expressed a desire to see more Gregorian chant and Latin in the Masses. But his saying so doesn’t make it happen. The trained musicians HAVE to be there for this to happen. He can wish all he wants, and I respect him and would gladly acquiese. But the musicians aren’t there.
One more thing that complicates our situation is an incident that occurred seven years ago. The one knowledgeable organist/musicians in the diocese was involved in a scandal involving homosexuality, and he was asked to leave by the diocese. Many, many of the classically-trained musicians and other trained, professional musicians left the Catholic churches in disgust. At the moment, the AGO has our parish on the blacklist–no organist in the guild is allowed to play in our church. Most of the really good musicians that I know in this area refuse to sing or play in the Catholic churches in our diocese, and they train their students to feel the same way. There is a LOT of social liberalism among the good musicians, and this means that we get the people like me–the musicians who can play or sing reasonably well, but are not teachers or professional performers. This has continued now for seven years, and IMO, it’s getting worse. The actual event that precipitated the blacklisting has developed “legendary” status, so that the facts are obscured and all most musicians know is that the Catholic Church is “anti-gay” and therefore, a “bad” place to go and sing or play. It’s very sad. I think that this is possibly one reason why our bishop doesn’t insist on Gregorian chant or other ancient forms of music–he’s a smart man and he knows that he can’t get blood out of a stone. I think he prefers to count his losses and accept that if he has musicians like me to work with–“Miss Gospel Piano”–well, that’s better than no music at all in the Mass. (I know that some of you prefer no music to contemporary music, but you are the exception–most people prefer some music, even if it’s bad music. I know I do.)
