The Choralis Constantinus II Print
Heinrich, Isaac, Tomus Secundus Choralis Constantini
(Nuremberg: Hieronymus Formschneider, 1555).
The second volume of a three-volume set. Volume I was published in 1550 and volumes II and III in 1555. The second and third volumes were produced together, with the dedication and publication information applying to both of them. The dedication, to Johann Jacob Fugger, is signed by the Augsburg book dealer Georg Willer, who purchased the materials for the print from Ott's widow in 1554.
4 partbooks (discantus, altus, tenor, bassus).
Facsimile edition, ed. Edward R. Lerner (Peer: Alamire, 1992).
Modern edition, ed. Anton Webern, Denkmäler der Tonkunst in Österreich 16/i (Vienna: Österreichischer Bundesverlag, 1909).
The print was checked, and a number of errors were corrected by hand, before the book was released for sale. In-house corrections can be identified by the fact that they appear in all, or nearly all, copies of the print. They apply only to the music (notes, rhythms, clefs, key signatures, accidentals, and mensuration signs), not to the texts. Despite the printer's efforts, many errors remained uncorrected.
The texts are treated much more carelessly than the music in the print. Text placement is imprecise, and often simply incorrect. Errors of word choice, spelling, and grammar are common.
There is a very brief errata sheet, which lists only two errors (both in volume II), at the end of the tenor partbook of volume III. Some copies of the print mark these errors by hand on the pages where they occur.
Twelve complete or partial copies of the print survive today. Some of them have handwritten annotations other than in-house corrections that reveal evidence of practical issues faced by the performers.
