Qualitative Information Flow in Generating Processes of Musical Interpretation Focusing on Meaning Structure of Rhetoric

This paper proposes a mathematical framework that visualizes understanding process of rhetoric that is used for musical interpretation. This rhetoric play a role in loosely constrain-ting the implicit notion and leads a way for the interpretation. We firstly state the semantic structure of the rhetoric representations´ handling process. Based on it, we carry out an structure analysis of musical interpretations´ communication process. Furthermore, we propose a mathematical representation of generation process that represents performers´ internal representation, focusing on rhetoric´s´ semantic structure. Finally, we discussed about variations and hierarchy of rhetoric.
