The meaning of “culture” in musical expression needs to be defined more carefully because of the enormous amount of exchange that occurs between diverse peoples who share the same purpose over the course of time. In the Christian religion, it is the liturgy that describes the overall purpose for the music being employed. Therefore, in the Catholic sense of the word, culture needs to be understood broadly; the liturgical setting doesn’t change, yet the means by which the musical expression does. And, there’s always been a certain generosity within the liturgy that allows for amplification or reduction to occur. There’s been a lot of “lend/lease” going on over the course of time. An example of this from the early days of the Church would be how “Roman Chant” ultimately became “Gregorian Chant,” and how, in turn, Gregorian Chant eventually supplanted the Roman.
As I understand it, there was a form of chant that came out of the city of Rome that had been developed and used for their liturgies for (perhaps) hundreds of years. The Roman style was more florid than what we associate with Gregorian Chant, with a higher degree of ornamentation and melismatic emphasis. But, sometime in the mid-700’s AD, the Roman form of the music traveled north into the Gothic/Frankish kingdoms where it was transformed into a form which we now commonly associate with Gregorian modalities of chant. The ornamentation over time was stripped away, but much of what was received by the Franks from the Romans remained in place because the liturgy itself was essentially the same. This Gregorian model, eventually then, became the norm even for the city of Rome.
Music changes over time and distance, and what was once the norm can also (and perhaps, inevitably, will) change.
That’s why when I hear the solemn and deeply moving 19th Century
Negro Spiritual “Were You There” during our Good Friday liturgy, I accept it as being totally appropriate for use the U.S. Church as a hymn for reflection. It’s a part of our collective American culture. While it’s not a formal part of the liturgy, it’s appropriate (I think) for use in the liturgy. Time will tell.
