Summary

Participants use a web-interface to generate sounds as part of a shoal.  Simple rules, based on shoaling behavior in fish, act as a social algorithm and guide gameplay.

For the Organizer

Ensure all participants are connected to the web interface (via the color-coded web links above) and can create audible sound via their mobile device.  Ask each participant to choose an initial waveform and frequency from the list of sound URLs, and to begin immediately by playing their selected pitch.  Set predetermined stop signal (e.g., a bell, a hand clap). 

For the Performers

After following the color-coded links (above) to the performance web page, choose a starting sound by clicking on the numerical list of pitches (i.e., numbers 400 through 1200, in hertz).  A continuous sound file will play.  Listen the pitch you are playing, in relation to the other notes you hear around you.  Decide whether you are playing the lowest note, highest note, or within the range of the pitches you can hear.  When that pitch fades out, choose a new note:  If your previous pitch was the highest, select a lower pitch (i.e., at least 4 pitch lower in the list); if your previous pitch was the lowest, select a higher pitch ((i.e., at least 4 pitch higher in the list)); if your previous pitch was within the shoal, select a pitch that is near to your previous pitch.  When conflicted, always react to the pitch-neighbour nearest to you.  Continue until the predetermined signal to stop.
