This paper shows finding of a resarch on the incidence of the performer´s actions in order to make a hierarchy of textural components, in the listener´s internal representation of them. Results show an important analogy with the previous tests findings. It is worth analysing all of them together in order to deepen the study of theri nature since it was possible to judge cases clearly where subjects can isolate: the main melodic line; the main melodic line and other pitches belonging to other textural components; onlu excerpts of the main melodic line; elements of other textural componentes no relatd to the main melodic line.
