The work we present in this paper is a formalism of a dynamic computational model in a hierarchy. We are interested in representing musical hierarchies and bindings of characteristics (such as the mode, measure, tempo, duration, key, etc.) within them in order to provide the composer a means to verify the consistency of the piece during the compositional process. The model transfers any modification from the composer to the representation in an incremental way, without computing again the whole hierarchy.
