Title: Klavierstücke (Stockhausen)
Content:   The Klavierstücke (German for "Piano Pieces") constitute a series of nineteen compositions by German composer Karlheinz Stockhausen. Stockhausen has said the Klavierstücke "are my drawings". Originating as a set of four small pieces composed between February and June 1952, Stockhausen later formulated a plan for a large cycle of 21 Klavierstücke, in sets of 4 + 6 + 1 + 5 + 3 + 2 pieces. He composed the second set in 1954–55 (VI was subsequently revised several times and IX and X were finished only in 1961), and the single Klavierstück XI in 1956. Beginning in 1979, he resumed composing Klavierstücke and finished eight more, but appears to have abandoned the plan for a set of 21 pieces. The pieces from XV onward are for the synthesizer or similar electronic instruments, which Stockhausen had come to regard as the natural successor to the piano. The dimensions vary considerably, from a duration of less than half a minute for Klavierstück III to around half an hour for Klavierstücke VI, X, XIII, and XIX.
Title: Zwei Klavierstücke (Schoenberg)
Content:  Schoenberg's Piano Pieces were just some of the smaller compositions that he made after finishing Von heute auf morgen and Moses und Aron. He started composing the first movement, Op. 33a, when the director of Universal Edition contacted him to publish the first piece in Op. 11 in an anthology of piano compositions. Schoenberg then decided to write a new piece on December 25, 1928, and finished it on April 25, 1929. The composition of the second movement, however, took only three days, from October 8 to 10, 1931, while he was staying in Barcelona. They were composed separately, but it is still unknown if Schoenberg had conceived them to be a full-length composition in itself. Both movements were also premiered separately. The first movement was published by Universal Edition in July, 1929, and premiered in Berlin, on January 30, 1931, by Else C. Klaus. The second movement was published by The New Music Society of California Publisher, in April, 1932, and premiered in San Francisco's New Music Society on January 11, 1934, by Douglas Thompson. Since then, it has also been published by Belmont Music Publishers and by Schott Music.

Title: Piano piece
Content: Johannes Brahms's Sechs Klavierstücke (Six Piano Pieces), Op. 118 ; Arnold Schoenberg's Drei Klavierstücke (Three Piano Pieces) ; Karlheinz Stockhausen's Klavierstücke A piano piece or piece for piano (Klavierstück, ; morceau [or] pièce pour (le) piano, ) 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 
Title: Zwei Klavierstücke (Schoenberg)
Content: I. Mässig ; II. Mässig langsam The two movements of this composition show the development of Schoenberg's twelve-tone technique, from its initial conception until its culmination in 1936. It takes approximately five minutes to perform both movements, and neither movement has a title. In some recordings, the movements are titled according to their tempo markings:  Both movements follow the principles of the twelve-tone technique, according to which a row of twelve tones is selected in order to construct the composition. The row of Op. 33a is 0 7 2 1 11 8 3 5 9 10 4 6. In order to compose the piece, Schoenberg uses inverted and retrograde versions of the row in various forms. The first movement starts with six chords, which show the row used in the piece.

Content:  Hindemith composed the music in 1923 to a commission by the pianist Paul Wittgenstein. He and his brother, the philosopher Ludwig Wittgenstein, belonged to a wealthy family of industrialists in Vienna. Paul Wittgenstein lost his right arm in the World War. To continue his career, he arranged works for left hand alone, and he commissioned left-hand piano pieces from leading composers of the 1920s, for his exclusive use, including Benjamin Britten, who composed Diversions, Erich Korngold's Piano Concerto for the Left Hand, Ravel's Piano Concerto for the Left Hand, Prokofiev's Piano Concerto No. 4, works by Franz Schmidt, and Parergon and Panathenäenzug by Richard Strauss. Hindemith was regarded as a promising young 
Title: Kammermusik (Hindemith)
Content:  Kammermusik No. 2, Op. 36, No. 1, was composed in 1924 as a chamber piano concerto, for piano and 12 instruments. The title on the composer's score is Kammermusik II (Klavierkonzert). It is structured in four movements: 1. Sehr lebhafte Achtel (very lively eighth notes) 2. Sehr langsame Achtel (very slow eighth notes) 3. Kleines Potpourri: Sehr lebhafte Viertel (little potpourri: very lively quarter notes) 4. Finale: Schnelle Viertel (fast quarter-notes) The piano part is not in the tradition of virtuoso pianism, but returns to mostly two-part writing, similar to Bach's Inventions. It is an early work in neo-Bachian style. The work is dedicated to the pianist who was soloist in the premiere: "For Emma Lübbecke-Job". It was premiered in Frankfurt on 31 October 1924, with the Frankfurter Museumsorchester conducted by Clemens Krauss.

His short operas Mörder, Hoffnung der Frauen and Das Nusch-Nuschi were premiered at the Staatsoper Stuttgart in 1921, and he was in the process of composing concertos entitled Kammermusik. He received the commission from Wittgenstein possibly at the end of 1922. The US$1,000 that came with it enabled the composer, originally from a poor background, to acquire the Kuhhirtenturm as his home from the city of Frankfurt. In a note added to the first mailing of the music in May 1923, he wrote: ""Here are the three final movements of your piece and I hope that your shock will subside after perusing the score. It is a simple, completely
