Sechs kleine Klavierstücke

Sechs kleine Klavierstücke, Op. 19 (or Six Little Piano Pieces) is a set of pieces for solo piano written by the Austrian composer Arnold Schoenberg, published in 1913.

After having written large, dense works such as Pelleas und Melisande, up until 1907, Schönberg decided to turn away from this style, beginning with his second string quartet of 1908. The following excerpt, translated from a letter written to Ferruccio Busoni in 1909, well expresses his reaction against the excess of the Romantic period:

My goal: complete liberation from form and symbols, context and logic.
Away with motivic work!
Away with harmony as the cement of my architecture!
Harmony is expression and nothing more.
Away with pathos!
Away with 24 pound protracted scores!
My music must be short.
Lean! In two notes, not built, but "expressed".
And the result is, I hope, without stylized and sterilized drawn-out sentiment.
That is not how man feels; it is impossible to feel only one emotion.
Man has many feelings, thousands at a time, and these feelings add up no more than apples and pears add up. Each goes its own way.
This multicoloured, polymorphic, illogical nature of our feelings, and their associations, a rush of blood, reactions in our senses, in our nerves; I must have this in my music.
It should be an expression of feeling, as if really were the feeling, full of unconscious connections, not some perception of "conscious logic".
Now I have said it, and they may burn me.

This work was composed at the same time that Schoenberg was working on his orchestration of his massive Gurre-Lieder. While he maintained a lifelong love of Romantic music, the extreme contrast between his Klavierstücke and his more romantic works comes from his modernist desire to find a new means of expression. For him, works like the Gurre-Lieder or Verklärte Nacht fulfilled the tradition he loved, but it was works like these Klavierstücke, or the Fünf Orchesterstücke that attempted to reach beyond it.
