from the collection of the British Library
From 1784 forward, Mozart got his act together somewhat—he maintained a fairly meticulous thematic catalogue of his own compositions, in which he recorded certain details regarding composition and performance dates and forces for each new work, as well as incipits—short “previews” of the opening bars of each piece.
This is the final page from that catalog. It records:
Mozart’s opening inscription on the first page states that the volume was to catalog all of his works from early 1784 until 1____, which suggests that he expected the catalog to run past the year 1800.
But the pages following this one are all blank.
