No. 51 Horizon (2012)
For cello, vibraphone, chinese gongs & sinewaves
Commissioned by Arnold Marinissen & Katharina Gross
#51 a) single-line version
#51 b) harmony version

Info/Program Note:
A single line for two players. Both alternate while speeding up and slowing down against a gradually changing click track. The cello part consists only of harmonics, starting high, eventually ending up an octave lower and then returning again to the initial register.
An alternate - harmonic - version of the piece also exists, for cello alternating against dyads in the percussion.
