This is the discrete concept for this exhibit.

Wikisonic is an installation that invites a shared experience in collaborative musical composition.

In the real life museum, visitors of this installation see a series of notes arranged on a wall similar to the notes on a musical staff.  Each note has a switch, with activates and de-activates both a light, and an audible tone (each note in a scale in the key of C) contained within each note/switch. 

A trigger perpetually circulates through the score.  As it passes by, it plays only the notes that have been activated by visitors. 

The installation has a corresponding virtual component located in Second Life.  When visitors active or de-activate a note, the Second Life installation changes, in real time, to reflect that change.  Likewise, visitors to the virtual installation can activate or de-activate notes, which are then turned on or off accordingly in the real installation.

As this collective 'song' emerges, it will constantly change, based on the collaborative decisions made by visitors to the real and virtual Wikisonic installation.

The 'song' will be continuously recorded and posted on a website.  This recorded song will be Open Source, and visitors to the website can 're-mix' or use the song for their own purposes, or improve them as they see fit.  They can then upload their own mixes back to the website, where their modified clips are then available to everyone else.
