Conclusions

In this report, we analysed different literature on gestures and on interface design for musical purposes. We suggested that it may be considered to depart from one group of gestures and then decide which technology to employ for the interface design. Some items have been numbered as guidelines for this design and are explained elsewhere.

We saw that the classification of gestures proposed can be tricky to employ strictly in the case of acoustic instruments, where gestures may be interdependent. One suggestion is the expansion of these classifications to encompass "biasing" or "limiting" gestures, such as embouchure in the case of a clarinet.

We finally suggested a separation of "mapping" in two groups: Mapping of performer gestures to musical functions and Mapping of musical functions to synthesis parameters. We consider that the strategy of mapping of controller data (performer gestures) to musical functions is a formalism to achieve micro or macrostructural control of the sonic result and is independent from the synthesis model used.
