  • informational content of movements in performances?

    Dear list,

    I am a PhD student interested in the interaction between percussionists and
    their instruments while performing. Until recently it has been on a very basic
    level, but I am now involved in a project studying the expressive content in
    performances. Musicians and dansers have the refinement of certain movements in
    common with athlets, but when performing the purpose of the movement is also to
    convey something, an expression. I think this makes these specialised movements
    of performers very interesting to study.
    I now wonder if any of you know about the informational content in the
    movements of the head/neck/shoulder and elbows as compared to the movements of
    the hands. What I am looking for is any hint of what the person is
    about to do e.g. compensation for the change of mass distribution before lifting
    an arm very quickly, or in what order the joints start moving when initiating a
    (skilled) transition or anything like that. I am also interested in anything
    done about the evaluation of the QUALITY of skilled performances (maybe jerk?).
    Please let me know if you have any idea of where to start looking. I'll post a
    summary of the responses as ususal.
