Some examples of what has been done so far in this field…

There are different references which work as mobile apps/ sort of video games:

SoundBrush iPad App

Pitch Painter iPad App

Aquasonic App

Windharfe App

Rehearsal: An app for practicing musicians

All of the previous references were designed as mobile applications, and as stand alone not collaborative apps.

The use of these apps in pedagogic work and their efficacy still has to be further researched and analysed.

Bjork’s Biophillia Album App Well known application, very interactive and visually compelling although focused on the artist’s album.
