Piano piece

In 1768 Carl Philipp Emanuel Bach published his Kurze und leichte Klavierstücke, 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. Klavierstück in F, K. 33b), or, as in the Neue Mozart-Ausgabe, to various single-movement compositions for solo piano or other keyboard instrument.

Since the middle of the twentieth century auxiliary instruments, tape, or live-electronics may be employed without changing the basic idea of a solo piano piece, for example Stockhausen's Klavierstück XVI.

There are also multi-movement works titled in the singular, as for example Michael Gielen's Klavierstück in sieben Sätzen "recycling der glocken" (Piano Piece in Seven Movements "Recycling of Bells") for prepared piano, bells, and tape.
