Sandro Magister has another liturgical piece up in Chiesa, From Vienna, a Lesson on How to Sing the Mass:
"Haydn's polyphony and the Gregorian antiphons of the ancient missal accompanied the papal liturgy in the Austrian capital, all of which was celebrated with "the gaze fixed upon God." A model for Catholic Masses in the Latin rite all over the world"
Magister also brings up the issue of the Papal Master of Ceremonies:
"In the Vatican, the liturgical event of Vienna will soon be followed by the replacement of the master of the pontifical liturgical celebrations. Taking the place of Piero Marini – who will go to preside over the pontifical committee for international Eucharistic congresses – will be the current master of ceremonies for the archdiocese of Genoa, Guido Marini. He's close to his predecessor in name, but to pope Ratzinger in substance."
