And a big bellowing organ is somehow more appropriate? Or even pholophony…which sounds an awful lot like aboriginal chant? What can get more secular than a sound that godless natives make?
My views on drum kits at mass have been expressed enough on other threads. I don’t know what kind of polyphony you were listening to, but I don’t think it (meaning sacred polyphony) sounds anything like that below.

Not putting it down as I think it is very interesting to listen to, especially with western ears and only training in Western Art Music and having to make myself understand it from the perspective and whatever rules they have for their form of music.

**That said, original polyphony, (and I know I’ve said this many times on other threads, but I think it is always important to point out to ensure that people just don’t believe that polyphony was always sacred music) before it was refined enough for the Church to recognize it as appropriate for liturgy, was considered to completely secular in sound and totally inappropriate for mass. ** It was often referred to as “lascivious”, “inciting lust”, etc. by contemporaries of the time when polyphony was creeping into the liturgy. It was, by all regards, popular secular music for the time and was banned for use in liturgy three popes at various periods. It wasn’t until Guillame de Machaut actually refined the composition of polyphony as well as the execution of it by the voices that it was deemed appropriate for mass. There is a difference from the sound of polyphony secular music to sacred polyphonic music and when we had to perform it in college, we had to learn not to sing it as smoothly and “solemnly” as we did with sacred polyphony. It’s a bit more “upbeat” and with a little more staccatto-like singing. Some of the vocal secular polyphonic music we sang was very similar in style as this and that was what the Church was against and banned for liturgy at the time.

The sacred refinement of polyphony continued on and Palestrina was considered one who really perfected it by those in the Church at the time and today.

Now, throughout the centuries different kinds of instruments and popular styles of music has crept into the liturgy and the Church has had to reign it in. Operatic singing, for instance, was very popular for a while at mass (it was one of different kinds of popular vocal music at the time… literally considered music for the common people and not for the intellectual), until the Pope had to put the stops on it and singers had to reign their voices in… they had to refine it for liturgy.
Now, the “problem” is with the popular music of today, which usually consists of rock-like bands, folk groups and such. Perhaps some of these instruments and styles of singing can also be refined like so many other “popular” styles of singing and music was refined throughout the centuries. Only time will tell. But we are currently in a transitional time where I haven’t seen yet, this kind of refinement, yet have been seeing more Church authorities in different dioceses or at least in individual parishes begin to request that the music and “performance” of the music be more refined or request that the instruments used not sound completely like a secular rock concert. For instance, I’ve heard an acoustic guitar played absolutely reverently and beautiful for mass and actually cantored a very traditional wedding mass (chanted Latin mass parts, etc) with with a classical guitar and violinist since the organ was out of commission. It was extremely reverent and spiritual. So, although I do believe that the organ does have pride of place and should be used (although I prefer it to be played well because when it is not, I’d rather not hear it at all - classical organ played well can be beautiful) whenever possible, I do believe other instruments could possibly be used if they can be refined.
I just don’t abide by the idea that just because other instruments can be used, that you can just play the instrument any way you like. And I only believe in this due to how the Church has handled it in the past and today. As much as I would love to sing some religious pieces that require an operatic voice at mass because there are some really gorgeous religious vocal music, I still don’t believe it is appropriate, even though when I’ve had to sing that kind of music at mass by various music directors, people have told me afterward how spiritual, beautiful and moving it was.
Anyway, just my thoughts.
