Abstract:
Boulez’s Éclat (1965) is a work that prefigures features many technical and aesthetic features that became standard in his later works (post-1975). This analysis of a brief fragment from the opening piano cadenza, illustrates how his serial developmental techniques can create passages that feature large common subsets, embellished by other notes, which I have posited as one of the fundamental principles of his harmonic language. The analysis is based on a study of sketches for Éclat from the Pierre Boulez Collection at the Paul Sacher Foundation. I analyze the entire cadenza in a longer article published in Music Theory Online (Losada 2019).​​​​​​​
