Music ensemble performance is a particularly interesting context for studying communication and coordination, since the communication is largely nonverbal and the coordination has to be so precise. We present two studies aimed at investigating the nonverbal auditory and visual signals that musicians exchange during ensemble performance to communicate their intentions and coordinate their actions. In the first study, pianists performed duets with either violinists or other pianists as the presence and absence of incoming auditory and visual signals were manipulated. Participant pianists were found to rely primarily on the presence of incoming audio signals in order to synchronize with their duet partners, but also made use of visual signals â especially at entry and re-entry points in the music, following long pauses. In the second study, piano-piano, piano-violin, and violin-violin duos performed passages drawn from the beginnings of Western classical music pieces, under different 'leader' and 'follower' assignments. Performers' head movements and violinists' bow hand movements were tracked using Kinect sensors and accelerometers. We present preliminary data for this study, which is currently ongoing. Performers in the 'leader' role are expected to show similar patterns of head acceleration across pieces during the interval preceeding their first note onset. Both pianists and violinists are expected to use head-nodding gestures, and the duration of cueing gestures is expected to relate to the tempo of the piece. Similar motion patterns may be found in conductors' gestures and across a range of other instruments. ********* Time: Monday, 23rd March 2015, 6.30 p.m. sharp Location: Oesterreichisches Forschungsinstitut fuer Artificial Intelligence, OFAI Freyung 6, Stiege 6, 1010 Wien OESTERREICHISCHES FORSCHUNGSINSTITUT FUER ARTIFICIAL INTELLIGENCE Univ.-Prof. Ing.
