FLUTTER ECHOES - étude d'un prélude II
for string quartet
dedicated to Olivier Senn
duration: ca. 9 minutes
The twelve works in the Études d'un prélude series are all based on micromeasurements of timing and volume of Martha Argerich's recording of Chopin’s Prelude op. 28/4 in E minor, recorded in Munich on 22-25 October 1975 and released by Deutsche Grammophon as DG 2530 731, reissued as DG 415 836-2. The duration of Argerich’s original recording is 1'51".
Flutter echoes overlays the Chopin/Argerich material with echo patterns. The title refers to an acoustic phenomenon in which a rapid series of echoes is created by reflection between two parallel surfaces.
