A conference, entitled "Music and the Church: cult and culture fifty years after Musicam sacram" was
organized by the Congregation for Catholic Education and the Pontifical Council for Culture.
“The encounter with modernity and the introduction of [vernacular] tongues into the Liturgy stirred up many problems: of musical languages, forms and genres....We need to promote proper musical education, especially for those who are preparing to become priests – in dialogue with the musical trends of our time, with the demands of the different cultural areas, and with an ecumenical attitude.”(From his mouth to God's ear, and the ears of bishops and rectors of seminaries.)
A common topic of discussion in the most progressive* liturgical music circles is how greater emphasis on an "ecumenical" use of hymnody could have spared, at least those of us in the English-speaking world, from much ugliness and banality inflicted in the name of "getting the people to sing," no?
(Side note: this is the first time I've ever read the phrase "liturgical animators" except as a quotation from older, past-their-sell-by-date sources.)
* I mean, of course, the authentically progressive.
