Heptapiano - piano space for 7 automatic piano players

At the Ars Electronica Festival 2011, in the freeroom of lentos, seven automatic piano players of the serie Rhea has been arranged in an 20m diameter circle and played like an ambisonics spatial piano space. The commissioned work by the ars electronica center Linz has used as a base the 32th tope of Josef Matthias Hauer "Und die Wellen umspielen uns" for self replicant mutation algorythms embedded in noise waves of piano tones.

Piece for seven robotic piano players, 27min in the series of “social machines” Seven pianos placed in a circle of 20 meter diameter, forming a heptagram, are networked and form a piano space of 314m². With the new series of robotic piano player “Rhea”, 88 fingers on each of the seven pianos forms together a mass of 616 possible parallel notes, which can be played by the Autopianoplayer, and controlled via Ethernet from a central mixing station. They play together a composition where out of more or less chaotic behavior, like waves, little phrases as melodies and accords come to life, organizing and synchronizing themselves over the pianos. So an organic corpus of sound is formed and transformed and can be mixed live from a main control station. Synchronization and increasing differences are computed within mutation algorithm in the algorithmic composition. All this is surrounded by an endless composition “Evolution 3”, where melodies drift over the piano like the where in a big 2D spatialization space.
