We chart the composition and technical development of a non-linear, interactive work for pianist, Disklavier piano and interactive system called Climb!. Collaborating with a composer and performers we focus on the journey of score representations through this complex work, highlighting the processes and challenges faced from composition to performance. We reveal that multiple, distinct score representations of different types and formats were required to define and perform the work. Furthermore, we highlight a number of compromises that were necessitated to create and manage the work’s notations, representations and annotations.
