The principle of musical erratum is simple: you choose a keyboard, any keyboard; you draw each note at random; no note can be struck twice, but
all are struck; the resulting whole is played without any particular modulation, "a uniformity de rhythm, anaccentuation" says Duchamp. The premises of minimal and aleatory art are thus expressed in The Green Box, published in 1934 (although the writings date back to 1912-15).

Stephane Ginsburgh, although still young (born in '69), is already known as a great pianist by the critics. He loves his concerts to contain a mixure of styles - perfect in his performances of Robert Schumann, Morton Feldman and Stockhausen.

The pieces presented here were recorded, and map the journey, over six hours of a single day: the beginning lively and full of exploration, becomes gentler, almost Feldmanian... 36 minutes that swallow up the everyday world... a magical inverse version, then ending as evening falls: the last note, no. 63, is struck for the last time - it was also the first note, played six hours earlier...

This CD is the counterpart of another, The Creative Act, published by Sub Rosa in 1994, and edited by Marc Dachy. It contained, besides a luminous lecture given on the creative act in Houston, Texas 1957, two interviews dealing with, among other things, the readymade and a reading of 'à l'infinitif', and completed with a musical erratum played on a bellows harmonium by Jean-Luc Fafchamps, together with a vocal piece originally conceived by Marcel Duchamp for himself and his two sisters, Yvonne and Magdeleine (sung respectively by Jean-Luc Plouvier, Marianne Pousseur and Lucy Grauman)
