Chapter 2 demonstrates how the second and third Piano Pieces of Op. 11 form a cycle together with the first, in that they take up motives, harmonies, and processes that were introduced in the first piece, and use them to create narratives of conflict, elaboration, and solution – “musical ideas.” Op. 11’s processes include an expansion of pitch intervals within motives that generalizes into an expansion of pitch-class intervals within set classes, and an “explanatory” process that shows how unfamiliar pitch-interval collections can be reconciled to familiar motives through set-class identity with them. In Op. 11, No. 2, a conflict between set classes and motives similar to the one found in Op. 11, No. 1, is elaborated and resolved using the “explanatory” process, among other devices. In Op. 11, No. 3, the expanding and explanatory processes exist side by side in conflict, but rather than coming together in a solution, the expanding process simply crowds out the explanatory one, so that the “musical idea” is incomplete. My analysis of Op. 11, No. 3, pushes back against the common notion of the piece as “athematic,” in that it portrays the piece as a battle of motivic processes.
