G is also for Gesture

The role of gesture in music receives a lot of attention, but very little concrete analysis. Hector Rodriguez's program Gestus rigorously analyzes movement in film images, separating gestures from the objects or actors in motion and identifies the gestural vocabulary present in an entire film, gathering together the most similar gestures, abstracted from their identities and contexts, in this case from Feuillade's serial Judex. What could an equivalent form of analysis for musical gesture be like? (A more detailed web site for Gestus is here.)
