Einsiedeln 611 records a few examples of an unusual practice of the monks of Einsiedeln, the singing of some chants at Nones, prior to a feast's First Vespers, in anticipation of the days of certain important saints. Such services (consisting of an antiphon or an antiphon with versicle in the manuscript) may be observed for the following feasts: John the Baptist (f. 184v), Peter (f. 189r), Assumption (f. 213v), and All Saints (f. 237r). The fact that such a Nones service is included for the Common of Apostles (f. 251r) may indicate that this practice was more general than only for those occasions given specific chants for this service in the manuscript. It is not clear whether these anticipatory Nones services were conflated with or replaced the Nones service of the preceding day.
Some of the unusual Offices in Einsiedeln 611 have been edited in Analecta Hymnica and also appear in Andrew Hughes's Late Medieval Liturgical Offices, including Catherine (AH vol. 26, p. 69, LMLO CB24) and the so-called "Historia nova" for Benedict (AH vol. 25, p. 52, LMLO BE01) that appears in Einsiedeln 611 on the feast of his translation. The prose Office for Corpus Christi (often attributed to Thomas Aquinas) was not edited in AHbut was copied in LMLO under the siglum XCX. These Offices appear in several other sources in the Cantus database.
Other saints' Offices have not been edited in AH nor do they appear in LMLO. These include Meinrad, the hermit-founder of Einsiedeln (21 January); Sigismundus, martyred King of Burgundy (1 May); Felix and Regula, martyrs (11 September); and significant portions of the Office for Maurice and his companions (22 September).
There are only three invitatory tones that are written out in Einsiedeln 611. Presumably there were others on folios now lost. The three tones are those identified as GR, 5, and 3 in the Cantus database. For some of the tones represented only by incipit there is little doubt as to their identity: 2, 7, NE, HS, and PA. One tone (beginning DA, GF, GF) seems likely to be BL; another incipit (DA, AC, A) appears to refer both to the tone in general use on Christmas (CH) and to the tone represented as GR in the database.
A final tone seems to be one of those that was written on a leaf now missing from Hartker's antiphoner (St. Gall 390-391); its presence there can be inferred from a copy of Hartker (St. Gall 388) that includes it at the corresponding point in the series. It has been given the siglum HL. St. Gall 388 (and presumably Hartker) assign two antiphons to it, "Regem regum dominum" and "Surgite vigilemus." Einsiedeln 611 assigns the latter of these to the tone called 2 but assigns a second antiphon to this tone, "Ploremus coram domino," for the feast of Mary Magdalene.
The differentiae for each mode have been numbered with a two-digit system: a majuscule letter indicating the final pitch of the differentia and a sequentially-ordered numeral. For those differentiae that exist in slightly variant forms, minuscule letters (a-d) have been added as suffixes.
