Comedy gold here
Peter K rounds on the article and points out that the basis of the argument is fickle.
I will just point out two things.
That Gregorian Chant is monophonic is not an accident and is not so because people in the past were thick.
Think about it.
In the OT there are references to plucky stringed instruments.
So no-one ever plucked more than one string at a time. Ever.
People who lived in caves had bone flutes.
The Romans and Egyptians had trumpets.
Ye olde Danes had lurs, see the packets of butter.
But people never played more than one pitch at a time.
Until organum. Yay!
That the musical expression par excellence, of the Catholic Church requires us all to share a single melody line must be telling us something important about what it means to be a Catholic.
So rather than junking it, perhaps some effort to involve ourselves and experience it might be worthwhile.
