[Cadenzas for the first and last movements of the D minor piano concerto by Mozart Köchel 466]

Holograph.
A rough copy, with numerous revisions, of two cadenzas, one for each movement. The cadenza for the initial movement is a variant of the cadenza in the fair copy (ML30.8b.S37C3) and is related, though less closely, to Brahms's cadenza. The cadenza for the Finale is almost entirely different from the one in the fair copy.

Used as engraver's copy by J. Rieter-Biedermann, Leipzig.
