Drei Klavierstücke (Schoenberg) in the context of "Piano piece"

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 used in a title (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:

• Johannes Brahms's Sechs Klavierstücke (Six Piano Pieces), Op. 118
• Arnold Schoenberg's Drei Klavierstücke (Three Piano Pieces)
• Karlheinz Stockhausen's Klavierstücke

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.
