"Musical interaction at a Distance: Distributed Immersive Performance"

ABSTRACT

The Distributed Immersive Performance (DIP) project explores one of
the most challenging goals of networked media technology: creating a
seamless environment for remote and synchronous musical collaboration.
A number of research groups have presented one-time demonstrations of
distributed performance with varying degrees of success since the
1970s.  None, as far as we know, has focused on capture and recording
of musical experience and thorough analysis of realistic musical
interaction in an environment constrained by network latency and
reduced physical presence.  In this paper we present a comprehensive
framework for the capture, recording and replay of high-resolution
video, audio and MIDI streams in an interactive environment for
collaborative music performance, and user-based experiments to
determine the effects of latency in aural response on performersbse of
creating a tight ensemble, a musical interpretative and adaptation to
the conditions.  The experiments mark the beginning of our efforts to
study comprehensively the effects of musical interaction over the
Internet in a realistic performance setting.  The users and evaluators
of the system are the Tosheff piano duo, Vely Stoyanova and Ilia
Tosheff, a professional piano duo who have won awards and concertized
internationally.  We present preliminary results from our first two
sets of experiments: two players in the same room at separate
keyboards with direct visual contact and delayed aural response from
partner (between 0 ms and 150 ms), and the same experiments with
players swapping parts.  User responses are reported for experiments
using Poulencbere the movements are Prelude (score-recommended tempo
of 132 bpm), Rustique (46 bpm) and Final (160 bpm).  For the fast
movements (one and three), the players experienced the highest
difficulty in creating a tight ensemble at 50 ms and above.  In the
fast but not-so-rapid first movement, the players almost always rated
difficulty in creating a musical interpretation higher than ensemble
(synchronization) difficulties. In general, the users judged that,
with practice, they could adapt to delays below 50 ms.
