Connecting SUM with computer-assisted composition in PWGL: Recreating the graphic scores of Anestis Logothetis

This paper describes further developments of the SUM tool, initially developed for the sonification of images, towards the composition and execution of graphic scores. Closer integration of the SUM user library within the computer-aided composition environment of PWGL has allowed the composition and realization of more complex graphic scores. After first explaining the existing structure and sonification approach of the SUM tool, we introduce its new macro-structure utilising PWGL’s VIUHKA texture generator, which supports higher structural levels and thus the generation of more complex sonic events. As a proof-of-concept demonstration of SUM’s new macro scheme, we attempt to reproduce the graphic scores of Greek composer Anestis Logothetis, notable for his extensive graphic-sound taxonomy. We thus demonstrate the combined capabilities of PWGL and the SUM tool to support the computer-aided composition of graphic scores.
