Schoenberg's Piano Pieces were just some of his smaller compositions that followed Von heute auf morgen and Moses und Aron.

33b was a request by Schoenberg's former pupil Adolph Weiss for a new piano piece that Henry Cowell's New Music Quarterly could publish as Op.

The first piece was published by Universal Edition in July, 1929, and premiered in Berlin, on January 30, 1931, by Else C. Klaus.

[4] 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 was recorded at the Polydor KK Studio in Tokyo, in June, 1991, and was released by Deutsche Grammophon in Japan.
