The Max Maestro – an animated music notation system – was developed so as to enable the exploration of artistic possibilities for composition and performance practices within the field of contemporary art music, more specifically, to enable a large crowd of non-professional performers regardless of their musical background to perform fixed music compositions written in multiple individual parts. Furthermore, the Max Maestro was developed in order to facilitate concert hall performances where non-professional performers could be synchronised with an electronic music part. This paper presents the background, the content and the artistic ideas behind the Max Maestro system and gives two examples of live concert hall performances at which the Max Maestro was used. An artistic research approach with an auto ethnographic method was adopted for the study. This paper contributes new knowledge to the field of animated music notation.
