The brighter it gets outside, the more dark couleurs and even black I am wearing. And this is also my first time that I post an article more or less completely in black. But this short movie Pianoworks 13 combines beautiful live action and motion design directed by Julien Martorell with simple piano music by Polerik Rouviere. Four dancers perform different styles, illustrating the link between body, instrument and instrumentalist. The moves give birth to a sort of calligraphic language which is a representation of the moves themselves.
