Gestural shaping and transformation in a universal space of structure and sound

Due to its encyclopedial universality, the denotator format used to describe musical objects in mathematical music theory bears an unlimited potential for their representation and manipulation. However, the Note, Score and MacroScore denotators commonly used in practice to date merely describe the symbolic level of music, in a similar way to the standard MIDI format. In the present work, we extend the MacroScore form with physical frequency modulation sound parameters to create a unified musical space encompassing both structure and sound. We also adapt the recently developed RUBATO COMPOSER software module BigBang rubette so that (1) music compositions can be shaped and transformed in this unified musical space, and (2) these operations can be performed by intuitive gestures.
