My issues isn’t just with the style of the music. It is also the lyrics. There is nothing wrong with them. But they are not very deep and very repetitive.
Fair enough but as you said it was meant for common folk so is simple and easy to memorize. Perhaps more appropriate for working in the fields or on a chain gang…
Chant wasn’t designed to be sung by common folk. There was nothing “simple” or “primitive” about it. It was designed to be sung by exclusively by clerics in their daily liturgical offices and the Mass.
This is very true. Even the Divine Office, prior to the Council, was never intended for the laity. At Mass, all the great propers were chanted by the schola, I sing in a schola and it is true, chant requires some expertise to do well. And unless it was a dialogue Mass, the responses would be by the altar servers.
People complain sometimes that the OF Mass is a show, where the priest gets to show off, but much the same could be said of an EF Mass without participation by the laity. Some perhaps would pray along with the missal, in silence, but the evidence of many people simply clicking away a rosary or two during Mass is enough to suggest that, especially a solemn High Mass, was a lot of pomp and circumstance observed from the pews.
In monasteries, chant was usually complex enough that the community was divided into choir monks and lay brothers, the former dedicated mostly to the liturgy and studies, the latter to the manual labour. The lay brothers didn’t even attend the Divine Office except maybe on high occasions. They had their own Little Office; they often would attend a very early low Mass so they could get busy in the fields, while the choir monks had a later Conventual Mass.
Vatican II did away with these distinctions as St. Benedict’s rule never intended them nor mentioned them, so it’s no surprise that many monasteries adopted the vernacular and simplified their chant at the same time. Our abbey kept Latin Gregorian chant for Lauds and Vespers and hymns at the other hours, but does the rest in French plainchant.
