how

The Liminophone is an instrument that synchronises with tidal data from the NOAA (National Oceanographic and Atmospheric Administration) stations around urban waterfronts, generating algorithmic, real-time compositions using JMSL (Java Music Specification Language).

Each buoy becomes a polyphonic instrument, a character that changes with subtle fluctuations every six minutes.  The Liminophone interpolates the data between readings, mimicking the flow and force of a current and creating musical narrative.  

The Liminophone can be programmed to read any tidal-data-gathering buoy in the NOAA network.  It also generates phrases for its live collaborators to use for improvisation.  Multiple buoys can be played at once, creating a real-time choir of waters.

Everything is in real time.
