The famous prelude from Bach's Well Tempered Clavier.
I messed up the first recording at the end and I was too lazy to record the whole thing it again, so I did a little copy/paste at the end...
Recorded on a macbook using a Zoom H2 microphone.
Piano is a Sauter 108.
Le fameux prelude en do majeur de Bach, 1er morceau du clavier bien tempéré.
