A bagatelle, light, short, in reference to Beethoven's Bagatelle op. 126 n° 3, as if the latter had been altered, eroded and transformed by time. A melodic and harmonie metamorphosis of Beethoven 's main theme which by rotating on itself in canons produces a virtual harmonie reverberation; modification of the piano's timbre by a simple preparation of a few strings using two erasers and a sheet of paper; and resumption of the Beethovenian alternation between slow chords and fast arpeggios, all different examples of links to the original piece in paying a fleeting homage to this composer who is so important in my persona[ history. As at the time of my discovery of his work when I emerged from childhood: inner desert, sadness are transformed into a single question: "Why?".
