Source of pieces in Choralis Constantinus II: The Erlangen sources, D-ERu 473/1, D-ERu 473/3, and D-ERu 473/4, have a number of correct readings where all sources deriving from Ott's print exemplar share common errors. These manuscripts must therefore have been based on Ott's original source, most likely Isaac's autograph. The proximity of Heilsbronn to Nuremberg may explain the early access of the monastery to a source in Nuremberg.
Choralis Constantinus II contents:
- Mass 5
- Introit-Rorate coeli (fol. 18v)
- Communion-Ecce virgo concipiet (fol. 22v)
Character of variants in Choralis Constantinus II repertoire:
The versions of the Choralis II pieces differ significantly from the print only in their more accurate readings.
