MOZART AND THE PRACTICE OF SACRED MUSIC, 1781-91 a ...

a mass by Kozeluch himself has an annotation reading “Scritta per l’incoronazione del
Imperatore Leopoldi II re di Bohemia, benche non prodotta”, referring to the coronation
service itself on 6 September; see Figure 3.26. 262 Finally, a partially autograph set of parts for
another mass by Kozeluch has a note reading in pencil “Scritta per la Maria Teresia
imperatrice de Leopoldo II. Imperat.”, presumably referring to the coronation of Leopold’s
consort Maria Theresia on 12 September. With this new information, a partial performance
calendar for the coronation celebrations may be reconstructed; see Table 3.4. Just why
Kozeluch’s mass for the coronation itself was not performed is unknown, but it is possible
that some kind of “turf war” broke out between the Viennese Hofkapelle and the St. Vitus
ensemble. The presence of these annotations in parts belonging to St. Vitus strongly suggests
that the Cathedral was directly responsible for the music in some capacity.
From yet another set of parts in the St. Vitus archive, we know that another mass by
Leopold Hofmann was performed at the Prague coronation of Franz II in 1792, so Mozart’s
mass is out of the question for this occasion. If one had to suggest an Imperial context for K.
337, the most likely candidate is the coronation of Franz as Holy Roman Emperor in
Frankfurt on 14 July 1792. For this occasion, at last, we have relatively straightforward
evidence that a Mozart work was employed. In his 1963 article, Pfannhauser mentioned a
particularly significant source for Mozart’s motet Misericordias domini K. 222, and provided
a transcription of its title page. He did not however reveal the location of the manuscript, or
anything about its provenance beyond the fact that he discovered it in 1954 among the
remains of a “vormals sehr bedeutenden Dommusikarchives.” 263 As it turns out, Pfannhauser
himself owned the manuscript, and at his death in 1984 it was transferred to the Gesellschaft
262 CZ-Pak, 671. The autograph of this work and the Hofkapelle’s parts for it are in A-Wn, HK 313. The score
originally formed part of the collection of Empress Marie Therese; see Rice, Empress Marie Therese, 272.
