Mozart’s Thematic Catalogue
The title of Mozart's "Catalogue of all my works from the month February
1784 to the month [ ] 1[ ]" reveals that he expected to live into
the 19th century. Precisely why he began this catalogue is unknown. The
first three entries are the piano concertos, K. 449, 450, and 451. The
entry for K. 450 reads: "the 9th of February. / A keyboard concerto.
Accompaniment: 2 violins, viola and basso. -- (2 oboes, 2 horns ad libitum.)"
The ad libitum orchestration permitted Mozart to perform his concerto
with as few as four instruments or as many as a full classical orchestra,
depending on the occasion. When Constanze sold the catalogue to Johann
André, their contract stipulated that he would publish an edition
of it, which he did in 1805.
