In this paper we explore the potential of Expressive Notation Package (ENP) in representing electroacoustic scores. We use the listening score by Rainer Wehinger–originally created for György Ligeti's electronic piece Articulation–as reference material. Our objective is to recreate a small excerpt form the score using an ENP tool called Expression Designer (ED). ED allows the user to create new graphical expressions with programmable behavior. In this paper we aim to demonstrate how a collection of specific graphic symbols found in Articulation can be implemented using ED. We also discuss how this information can be later manipulated and accessed for the needs of a sonic realization, for example.
