finger tips and the hand root, or the arm, and of given constraints. Further steps would also take constraints given by playing techniques and style into account.
On the side of symbolic gesture curves, it is necessary to investigate the integration of instruments other than pianos and alike. While it is relatively easy to integrate string instruments, some research effort will have to be invested in how to apply the theory for example for wind instruments. Though we do not know yet whether possible or not - the ultimate step would of course be the availability of a single, general symbolic gesture space, which is valid for all conceivable instruments.
