In the last two decades the massive diffusion of Internet greatly widened the opportunities for new forms of musical interactions. Networked Music Performance (NMP) promises to revolutionize music fruition by allowing multiple remote players to simultaneously perform together from different physical locations by means of an Internet connection over a telecommunication network.
In order to reproduce realistic environmental conditions, multiple technical, psycho-cognitive and purely musical issues must be addressed. In particular, at network level, very strict requirements in terms of latency and jitter must be satisfied to keep the one-way end-to-end transmission delay below a few tens of milliseconds.
The sensitivity to delay and the quality of the musical experience in the context of NMP is influenced by several additional factors. We need skilled musicians to test how timbral and rhythmic factors affect the quality of NMP. In this page, you can find the scores and other material that will be played during the perceptive test.
We selected three songs, with different genre and increasing rhythmic difficulty:
We selected four main parts for the songs, which are: main melody (M), chordal comping (CC), sustained harmony (SH), and drums (D).
Here are the files for your part:
Zip files contain, for each song:
The guitar pro files can be opened with the free software TuxGuitar, which is available for Mac Os X, Windows and Linux.
It is crucial, for the experiment, that you are able to keep the tempo without a metronome. The initial tempo will be provided. Musicians are free to play with their preferred style, as long as they preserve the rhythmic pattern and they can keep the tempo when no delay is introduced.
The Networked Music Performance perceptive test is a study conducted by: Cristina Rottondi, Michele Buccoli, Massimiliano Zanoni, Dario Garao, Giacomo Verticale, Augusto Sarti.
