Piano Roll takes inspiration from Conlon Nancarrow and his studies for the player piano. While composing the work, I was interested in convergent and divergent distributions and different ontological problems that emerge when visualising and sonifying them. While the eye can be used to survey histories of consequence, the ear is only concerned with the immediate. Thus, I wanted to draw attention to the ear via the eye. To do so, I generated different distributions from a statistical feedback model and used them to sequence material, playing with ideas of ratio and space. Piano Roll was commissioned by the Laboratoire Musique et Informatique de Marseille.
