• developing variation German
  Entwickelnde Variation — Schoenberg's term for a compositional technique in which all subsequent material in a piece is derived by continuous transformation from an opening cell or motive, without literal repetition. The technique creates both unity (everything comes from the same source) and perpetual development (nothing ever returns unchanged). It is the fundamental constructive principle of Berg's Piano Sonata Op.1, where every theme, transition, and closing figure can be traced back to the opening rising minor sixth and its surrounding chromatic cells.
  In the Piano Sonata Op.1, the developing variation technique means the recapitulation is not a literal return — it is a transformation. Every 'return' of opening material has been altered in some way. Understanding this shapes how you approach the architecture: the piece is not a container for themes but a continuous unfolding process. Identify the opening motive and trace how Berg stretches, compresses, inverts, and reharmonises it.
• free atonality English
  Music that avoids establishing a tonal centre but does not yet use the systematic twelve-tone method. Free atonality emerged in the works of Schoenberg, Berg, and Webern around 1908–1909 as the logical endpoint of the intense chromatic language of late Romanticism. Berg's Piano Sonata Op.1 stands precisely at the boundary: it still has a key signature of B minor and returns to B at its close, but the harmonic language throughout is too chromatic to be heard as conventionally tonal. His Op.5 clarinet pieces (1913) are fully freely atonal, with no tonal reference points.
  Playing freely atonal music requires abandoning the expectation that dissonances will resolve in the familiar tonal way. In Op.1, tension accumulates differently: through developing variation, through the return of motivic ideas transformed, through registral and dynamic shape. Identify the motivic cells rather than chasing chord progressions.
• Second Viennese School English
  The informal name for the group of composers centred on Arnold Schoenberg in early 20th-century Vienna, including Alban Berg and Anton Webern as his two principal students. The term distinguishes them from the 'First Viennese School' of Haydn, Mozart, and Beethoven. The Second Viennese School developed free atonality (c.1908–1921) and then the twelve-tone technique (from 1921), transforming the harmonic language of Western music. Berg, Webern, and Schoenberg each took the techniques in radically different directions: Schoenberg rigorously systematic, Webern compressed and serial, Berg warmly expressive and resistant to rigid doctrine.
  Understanding the Second Viennese School places Berg's piano music in its full context. The Piano Sonata Op.1 sits at the threshold of the new language — deeply Romantic in feeling, atonally adventurous in syntax. Approach it as a late-Romantic work that has gone too far to turn back, not as an academic exercise in new technique.
