Fair-Copy Full Score
When completed, the full score of a concerto served as the source for
a copyist to extract a set of parts, which Mozart used for his performances.
Mozart sometimes had AN EXTRA SET of parts made for his sister or one
of his best students (for instance, Barbara Ployer or Josepha Auernhammer)
or a paying patron. In the present case he also apparently had a business
arrangement with the Viennese music-copying firms of Lorenz Lausch and
Johann Traeg to sell sets of parts, which were advertised in the Wiener
Constanze Mozart sold the autograph scores of the keyboard
concertos to the Offenbach music publisher Johann André in 1799-1800,
and gave Mozart's own sets of parts to their pianist-composer younger
son, Franz Xaver (W. A. Mozart fils); the latter are unfortunately lost.
