The main objective of this thesis is the design and application of a model, autoetnographically generated, suitable for the improvisation in the context of Art  music. Although the constitutive elements of the proposed model may come out from intuition, they must become explicitly expressed.  The operativity of the proposed model must be verified through the practice of other musicians of diverse levels of experience and ability. In the same way, the model should work as a tool in developing new artistic products.
