In KOORD, Bollen plays his version of this electronic instrument in combination with a traditional string quartet. The four-part composition takes the pure sound of strings as its starting point. The HyperTheremin creates a vast sonic landscape with slowly shifting sound fields interspersed with fast passages.
Prior to the premiere of KOORD, Jan-Bas Bollen explains the working of his instrument and introduces the HyperTheremin in a solo composition.
