Floodtide is a musical work by John Eacott which generates music from tidal flow. A submerged sensor gathers data which is transformed into notation for musicians to read from tablets or phones. The work is a live and ever-changing portrait of local tide. Beginning in March 2015 Floodtide begins its new project, Navigate. Sailing around northern Europe, UK and Ireland with a sailing yacht as its base, Floodtide will make tidal sonifications at coastal locations with local musicians. The project concludes at FON, in a 12 hour performance of an entire tidal cycle.
