The Pope is considering a dramatic overhaul of the Vatican in order to force a return to traditional sacred music.
The Pope wants to widen the use of Gregorian chant and baroque sacred music
After reintroducing the Latin Tridentine Mass, the Pope wants to widen the use of Gregorian chant and baroque sacred music.
In an address to the bishops and priests of St Peter's Basilica, he said that there needed to be "continuity with tradition" in their prayers and music.
He referred pointedly to "the time of St Gregory the Great", the pope who gave his name to Gregorian chant.
Gregorian chant has been reinstituted as the primary form of singing by the new choir director of St Peter's, Father Pierre Paul.
He has also broken with the tradition set up by John Paul II of having a rotating choir, drawn from churches all over the world, to sing Mass in St Peter's.
Mgr Valentin Miserachs Grau, the director of the Pontifical Institute of Sacred Music, which trains church musicians, said that there had been serious "deviations" in the performance of sacred music.
"How far we are from the true spirit of sacred music. How can we stand it that such a wave of inconsistent, arrogant and ridiculous profanities have so easily gained a stamp of approval in our celebrations?" he said.
He added that a pontifical office could correct the abuses, and would be "opportune". He said: "Due to general ignorance, especially in sectors of the clergy, there exists music which is devoid of sanctity, true art and universality."
Mgr Grau said that Gregorian chant was the "cardinal point" of liturgical music and that traditional music "should become again the living soul of the assembly".
The Pope favoured the idea of a watchdog for church music when he was the cardinal in charge of safeguarding Catholic doctrine.
He is known to be a strong supporter of Mgr Grau, who is also in charge of the Cappella Liberiana of the Basilica of Santa Maria Maggiore in Rome.
