Under this definition, the musical structure may not be unique, and may even be ambiguous. One way to resolve that ambiguity is to see this task as a compression process, and to consider the musical structure as the optimization of a given compression criteria. In that viewpoint, C. Guichaoua developed a compression-driven model for retrieving the musical structure, based on the \"System and Contrast\" model,","authors_text":"Axel Marmoret, Fr\\'ed\\'eric Bimbot, J\\'er\\'emy E.
