La spirale du pianiste en streaming

Judith Abitbol filmed the work of pianist Jean-Louis Haguenauer. More precisely his work on the twenty-four preludes of Claude Debussy. It was a question of filming the elaboration of the work of the interpreter, such as Jean-Louis Haguenauer conceives it, at home, alone, in front of his piano. What does he do for hours at his piano? What is his approach to the work? How does he find his interpretation?.
