 Although the main focus of Milstein's work for the last two decades has been in composition, there is much overlap between her analytical work and compositional thinking.For instance, her article on the first movement of Alexander Goehr’s "Schlussgesang" (2003) is an attempt to provide a hypothetical reconstruction of the compositional process, from an embryonic sketch (displaying many technical annotations) to its fully fledged realization.This is the first study to offer a comprehensive technical discussion of Goehr’s post-serial harmonic practice in its aesthetic context, and explores Goehr’s synthesis of French and Austro-German approaches to tonality and modality and their relation to his understanding of Schoenbergian dodecaphony.
