Arnold Schoenberg's Suite for Piano, Op. 25, is a 12-tone piece for piano composed between 1921 and 1923. The work is the earliest in which Schoenberg employs a row of "12 tones related only to one another" in every movement: the earlier 5 Stücke, Op. 23 (1920–23) employs a 12-tone row only in the final waltz movement, and the Serenade, Op. 24, uses a single row in its central Sonnet. The basic tone row of the suite consists of the following pitches: E–F–G–D♭–G♭–E♭–A♭–D–B–C–A–B♭.
