• tone-row English
  Also called a twelve-tone row, series, or Grundreihe (basic row). The ordered sequence of all twelve chromatic pitches that forms the structural foundation of a twelve-tone composition. No pitch appears twice in the row until all twelve have appeared. The row is not a theme but a precompositional ordering constraint; themes, harmonies, and textures are all derived from the row in its four standard transformations (original, inversion, retrograde, retrograde inversion) at all twelve transpositions — giving 48 possible forms. Schoenberg believed the row gave atonal music the same kind of internal coherence that tonality had previously provided.
  Understanding the row analytically helps enormously when learning twelve-tone piano music, but the performance goal is always musical expression, not serial demonstration. In Op.25, the row is audible as a surface gesture in many places; in Op.42, the serial organisation is more absorbed into a lyrical, almost tonal surface. Let the row inform your understanding of phrase structure and motivic return without making it the basis of your expression.
