When musicians at multiple physical locations attempt to play together, the limiting factor is unavoidable packet delays and jitter introduced by the IP network that connects them together. This research investigates the musical tolerance of adverse network conditions as a function of rhythmic complexity and tempo. Results show that with higher network latency: (a) musicians exhibit a more pronounced tendency to decelerate with more rhythmically complex pieces; (b) rhythmical complexity does not significantly worsen musician perception of the delay and interaction quality; (c) among the timbral features, instruments with a higher spectral entropy and spectral flatness (such as guitars and drums) lead to larger tempo slowdown. Low-latency networks promise to revolutionize interactive music such as remote rehearsals and music teaching.
