With the prepared piano, percussion and noise enter physically inside the grandpiano and changes it.
I try to produce an electronic piano preparation; elements of "hardware" (iron, nails, wood ...) then disappear in favor of the computer program (software).
Electronic preparation offers a great variety of acoustic interference, the possibility of articulating the complex preparation and development of this preparation controllable by the standard keyboard interface Disklavier via MAX / MSP program.
In "Variazioni knew a Preludio di Skrjabin" (Prelude op.45 n.3), speakers are placed inside the piano spread sampled sounds (synthesis by physical models Genesis ACROE, Grenoble) that create interference with the acoustic sound.
Automation opportunities offered by the Yamaha Disklavier establish a new dialogue between pianist and instrument. The theme of the double and the mirror is obvious: the other piano "virtual", played by the same keyboard, dynamically and dialectically interferes with the acoustic piano. And "physical models" strings Genesis create a duplicate of the real piano and a virtual "hardware".
