Original Kurzfassung:
Expressive timing is vital for the aesthetic quality that makes us appreciate
performed music. It is a largely tacit skill that musicians acquire
by practice. A long-standing intuition is that expressive timing
is closely related to the concept of motion. This view leads naturally
to the adoption of a dynamical systems approach to the study of expressive
timing. A well-known visualization technique from dynamical
systems theory is the phase-plane representation. The application
of this technique, that highlights the dynamic aspects of the data, is
demonstrated in a case study on the final ritard in performances of
Schumann’s Träumerei. We argue that expressive gestures are visible
in a clear and intuitive manner in the phase-plane representations. Another
striking aspect of the phase-plane trajectories is their suggestion
of human gestural motion.
