Hans van Koolwijk makes sound art. He experiences sound as an almost
tangible material and works with it the way a sculptor works with stone or clay. As an artist he has always felt the need to visualise sound as an image:
sound becomes something you can see.
Hans van Koolwijk works with composers and with ensembles. The works he produced have been used by visual artists, designers & architects, and
moviemakers. By collaborating with composers, musicians, choir, dancers, and other sound artists, his work has become more versatile.
