Jord Og Himmel (2009) by Rob Hamilton is an improvisatory work written for the Stanford Laptop Orchestra (SLOrk) using q3osc and ChucK. Performers control avatars in a virtual environment, firing sound-projectiles which interact with the environment either by bouncing off of the virtual architecture or by tracking individual performers. Projectile collisions are musically sonified by synthesizing a filtered noise burst with every bounce or by tracking a sine tone with pitch determined by the current coordinate location in space.
Written for the full 20-seat Stanford Laptop Orchestra, Jord Og Himmel continued the exploration of 3D musical environments begun with 2008's nous sommes tous Fernando.... The work was premiered on the SLOrk Spring Concert in Dinkelspiel Auditorium, Stanford University on June 4, 2009.
