Pope Francis speaking to the Third International Meeting of Choirs this past Saturday:
You are the musical animators of the whole congregation. Don’t take its place, depriving the people of God of the chance to sing with you and bear witness to the Church’s communal prayer.
The root in the word animator in English is “spirit.” While I have no problem with another oft-quoted musical quality, solemnity, it has its place. But only as a mood when prayer and liturgy suggest it–which is not all of the time. The constant task of music is to petition the Holy Spirit to animate the entire people.
