This paper aims to explore the potential of merging acoustic music with digital media and other art forms to create non-linear compositional forms. Often, it’s difficult to get away from traditional composition processes, make a piece adaptive in form and not strictly bound to time. Through case studies on works by Walter Giers, Michel van der Aa, Yannis Kyriakides and more, I focused on the elements of integration, interaction and nonlinear composition of different media. Looking at their work and through self- experimentation, I noticed that the different media can get dramaturgical meaning and interact live with every element of the performance. Digital media can specifically function as tools for interaction between the performers and the audience. By incorporating playful ideas in the compositions, derived from the world of games and indeterminacy, we can end up in nonlinear processes of performing notated music and allow for interpretation by other artforms. As a result, I composed the pieces In Medias Res for musicians, circus artists and interactive media, Dots for Pierrot ensemble and visuals, the 15’ opera Aer and the interactive music game A poppy blooms. Through this process, I tried to free myself, as a composer, from specific writing habits and approaches. A new field of possibilities opened up on how to develop music material, notate it and perform it.
