This article presents an approach to music interaction and creativity at both the symbolic and
structural levels. Even if the creation of common music occurs at the symbolic level, the structural
level allows interaction with music contents at a higher degree. This requires a tool to formalize
music fragments and their relations in terms of transformation functions. Using Petri Nets as a tool,
even real-time music composition is possible and, thanks to IEEE 1599, this interaction is
performed simultaneously at different levels. After an introduction of the main concepts, the article
describes a case study based on “Peaches en Regalia”, by Frank Zappa, presented at the
International Conference of Esemplastic Zappology, ice-Z, which took place in Rome on 9-10 June
2006. Finally, advanced realtime interaction scenarios will be presented.
