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.

The songs

We selected three songs, with different genre and increasing rhythmic difficulty:

  1. Pop Beatles - Yellow Submarine
  2. Balletto Maurice Raverl - Bolero
  3. Funky Stevie Wonder - Master Blaster
For each song, you will be asked to play an extract of about one minute.


The parts

We selected four main parts for the songs, which are: main melody (M), chordal comping (CC), sustained harmony (SH), and drums (D).

  1. Main Melody (M): the lead part
  2. Chordal Comping (CC): for fast-attack instruments, such as piano and guitar
  3. Sustained Harmony (SH): for low-attack instruments, such as strings
  4. Drums (D): for drum-set and percussions


The scores

Here are the files for your part:

  1. Main Melody
  2. Chordal Comping
  3. Sustained Harmony
  4. Drums

Zip files contain, for each song:

  • a pdf file with the scores
  • a guitar pro file with the scores and the tablatures (where needed)
  • the mp3 file of the song
  • the mp3 file of the song trimmed to the part you will be asked to play
  • a MIDI (musical ...) file of the original song
  • a MIDI file of the only part of interest
  • a MIDI file of the part of interest with double volume with respect to the others

You can use several softwares to read MIDI files, such as Van Basco for Windows and Midi Trail for Mac OSx.

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.
