Interpersonal communication and the coordination of actions are
fundamental human capacities and central to success on tasks such as
driving a car, playing sports, or playing music as part of an ensemble.
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 – 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.
