The vertical arrows denote shifts of interest between ideosyncratic structures and
theoretical problems. The horizontal arrows denote mathematical modeling (left to right)
and music-theoretical interpretation of mathematical facts (right to left). Mazzola’s
earlier investigations (e.g., on modulation and counterpoint) started from theoretical
problems and are hence located on the top side of the square. The analytical
applicability of these approaches is limited to very special musical structures. As a
consequence, Mazzola’s later investigations within the context of the RUBATO-project
aimed at reaching the bottom side of the square as well. The analytical RUBETTEs are
software tools to be used within the RUBATO frame application. They provide methods
for the analysis of scores (given in MIDI-format) through the transformation of
empirically given sets of tones (in the onset-pitch space) into highly structured
mathematical objects and finally encoding them in analytical weigths. These
transformations are motivated by general ideas on paradigmatics and syntagmatics,
but they are not comparable to grammars. There is no normative distinction
between well-formed and ill-formed musical structures. The RUBETTEs work
on any set of tones. As a consequence, there is a division of labour involved
between
In the case of the existing RUBETTES6
We recall the remark about the engagement of a modelist in his model resulting in a shifting focus of scientific interest. Once a mathematical model of a specific music-theoretical situation is established, it asks for separate attention. What distinguishes a model from a mere description is its metaphorical mechanism. The more knowledge about the model can be transferred into the music-theoretical domain, the richer its explanatory power. Hence, gaining knowledge about the model is a necessary prerequisite for the metaphorical transfer. It is essential that the researcher moves with the focus of his interest from the object domain to the model and back.
