Klavierstück

A piano piece or piece for piano (German: Klavierstück, pronounced [klaˈviːɐ̯ʃtʏk]; French: morceau [or] pièce pour (le) piano, pronounced [mɔʁso puʁ l pjano]) is a piece of music for piano. It is a generic name for any composition for the instrument, but when capitalised (Piano Piece, Piece for Piano) the name is used to indicate a (usually) single-movement composition for solo piano that has not been given a more specific name (such as Sonatina, Allegro de concert or Le Bananier), for example:

As the German word Klavier may indicate other keyboard instruments besides the piano, not all Klavierstücke are composed for the piano; for example, the pieces included in the Klavierbüchlein für Wilhelm Friedemann Bach are rather to be regarded as keyboard pieces than piano pieces.

In 1768 Carl Philipp Emanuel Bach published his , Wq 113. In this case each of the 11 pieces included in the volume has a separate title (Allegro, Arioso, Fantasia, etc.). For Mozart's compositions, Klavierstück may refer to posthumously published pieces without a definite title (e.g. , K. 33b), or, as in the Neue Mozart-Ausgabe, to various single-movement compositions for solo piano or other keyboard instrument.
