Character of variants in Choralis Constantinus II piece:

The copyist Johann Buchmayer, who was originally from Nuremberg, was also a composer. His works occupy nearly half of MS C 100. He had a habit of modifying works of other composers that he copied, in particular by filling in thinly-textured passages with additional voices. That procedure is evident in mm. 7-8, where a two-voice passage is rewritten to include all four voices. The other musical variants in his copy, though relatively numerous, are minor differences in pitch and rhythm of the types that are common in many sources. See Friedheim Brusniak, “Der Kodex A. R. 773 (C 100) von Johann Buchmayer in der Proske-Bibliothek zu Regensburg,” in Bericht über den internationalen Musikwissenschaftlichen Kongress Bayreuth 1981 (Kassel, 1984): 288-94.
