Plainchant isn’t Gregorian chant.
Popes over the years have also gradually allowed more and more to be done, such as the inclusion of kettle drums.
Correct, plainchant also includes Ambrosian chant, Mozarabic chant, Beneventan chant (defunct), plainchant in the vernacular, Sarum chant, Anglican chant.
Moreover I bet if you ask more than one traditionalist which Gregorian mass setting they prefer, they’ll answer “Mass VIII” (aka Mass of the Angels) which isn’t even Gregorian, it’s neo-Gregorian, and post-dates Gregorian chant by some 500 years or so.
I am very much in favour of Gregorian chant, I must admit a soft spot for it. It should be preserved, and it is. In Canada, there are at least two monasteries that use it daily (both Benedictine, men at St-Benoît-du-Lac, Quebec, and women at Ste-Marie-des-Deux-Montagnes just west of Montreal). There are also numerous groups promoting it. I sing in a schola in the archdiocese of Sherbrooke, and we rotate once a month to different parishes. Then of course there’s Solesmes in France where the scholarly study of old manuscripts takes place. Solesmes is mandated by the Vatican to study and preserve Gregorian chant.
I am a strong promoter of the use of Gregorian chant for the OF Mass as well as the Liturgy of the Hours. Our schola does both; we only sing at OF Masses (not because of some allergy to the EF… more because there aren’t any close by that aren’t SSPX).
However, we don’t impose, we propose
