Analysis and Composition With the beginning of the 20th century, there was an expansion of tonality in music and a departure from traditional harmony. This led to a spectrum of new compositional possibilities. More than in the preceding centuries, these compositional techniques are (and were) simultaneously valid, so that the parallel diversity outweighs the chronological succession. Christoph Wünsch explains the central compositional techniques and illustrates their structures step by step. This not only provides access to this music for readers who engage with it from a compositional perspective, but also for musical analysts. The author's many years of teaching experience is also reflected in the numerous worksheets with tasks and solutions included on the accompanying CD-ROM (PDF files, suitable for PC and Mac).
