Diurnes #1 is a 7-hour long sound synthesis composition and gallery performance driven by data from tide level measurements of the river Thames by Canadian artist David Gauthier.

The piece begins at a predicted Thames high tide level at 12:17 and ends 19:05 at low tide.

Tides are one of the slowest waveforms affecting the earth daily. The composition is programmed to be performed as slowly as possible on custom made synthesisers, which receive data transmitted from sensors on the Thames. The resulting composition is then broadcasted live.  

Visitors may attend anytime during the event. A map with a walking route from the gallery to the Thames will be available during the performance, with an option to continue to listen live to the composition on

The title of the piece is taken the gravitational pull of the moon (semi-diurnal) on the earth’s body of water, which produces the tide phenomena. In its approach to composition Diurnes #1 can be seen in the tradition of the musical compositional style known as Nocturne, a musical style popular in classical music that is intended to be evocative of the night, and which were often played late, after dark.  

This event will be broadcast live and recorded for webcasting.
