Recordings:

  • under the direction of the late Fr. Roman Bannwart, O.S.B., on Spotify and YouTube; these recordings generally agree with the semi-mensuralist rhythmic theories articulated by Dr. Dirk van Kampen in this article

Note: Most if not all of the following sites presuppose a nuanced, non-proportional rhythmic interpretation.

Restored Editions:

  • Graduale Authenticum - the best online resource for viewing the oldest manuscripts; arranged according to the novus ordo Roman calendar

  • Graduale Synopticum - same edition and numbering as the Graduale Authenticum, with different search options; the Antiphonale Synopticum is accessible at the same site

  • Introits from the Graduale Novum - triplex edition incorporating the melodic corrections of the AISCGre working group published in the journal Beiträge zur Gregorianik

  • Graduale Restitutum - duplex edition incorporating the AISCGre melodic corrections, arranged according to the novus ordo Roman calendar; normally the same reading as the Graduale Novum

  • Col Nostro (Italian) motu proprio of Pope St. Pius X authorizing the Vatican chant edition and permitting the approval of other books only if the variations in the chant come from good manuscripts (paragraph D)

  • Pietras Dubia & PCED Response (2018) tolerating chant editions and interpretations other than Solesmes/Vatican, no. 24; note that Pérès and his disciples use editions that sometimes differ considerably from the Vatican edition
