Abstract
The philosophical model of constellation has been applied to contemporary musical form, but it reveals too many limitations when confronted with late Adorno’s model of informal music. Once the component of heteronomy, in hierarchical and centered structures of traditional music, has been overcome, it reemerges in the opposite type, the decentered, non-hierarchical or free structures, between the opposites of serialism and aleatoric music. Therefore, the model of informal music, as an "image of freedom", pursues the realization of a musical-aesthetic nominalism that is subtracted from all forms of heteronomy, ancient or modern. To do this, it has to achieve the 'actually constructed totality' of the work, integrating in it the opposite of free subjectivity.
