Parody Technique in Masses the Imperial Chapel
Seven extant manuscripts copied by scribes either at the chapel or, as in the case of Andreas Reinschall, with probable access to the chapel's materials will be discussed in Chapter IV. Of these seven sources, VienNB 15948, 15951, and 16194 were copied by scribes at the chapel for use at chapel services. The reasons for the selection of Masses included in these sources are not explicit; however, as extant sources they help to identify the music heard in Vienna and Prague during Rudolf's reign. Implicitly, the selection represents the ideal of Mass settings valued by the court. The expense of copying necessitated a narrowing of Masses available for reproduction by the scribes, and the ensuing selection would have been effected, in part, on an undefined qualitative basis.
