Bathymetric Terrains is a work that muses on the ecology of oceans and tidal bays. Bathymetry is the measurement of water depths. Bathymetric maps chart the land that is covered by water.

Bathymetric Terrains is an electroacoustic composition for live performance, computer processing and soundscapes. The work includes multiple flute, guitar, and voice parts. The solo flute and solo guitar parts are performed live while all of the additional parts, processing, and soundscapes are projected through a PA system. The additional parts can be played by live performers—an additional 5 flutes/bass flutes, 5 additional guitar parts, and a minimum of 2 voices can be performed live with the two solo parts. All parts are to be amplified.

Max/MSP/Jitter is used to control all events during performance. A MIDI foot controller is necessary for one of the performers to advance events during the performance. Movement 1 includes improvisation for the live performers, movements 2, 4, & 7 include click tracks to coordinate with the videos and the multi-tracked materials. Movements 3 and 5 are fluid, and movement 6 is created using FM/AM synthesis techniques directly in the patch. The setup is optimized for quad playback on four speakers, two in front, and two at the rear of the hall.

For the initial performances, Eugene Cormier has recorded the multiple guitar parts and Derek Charke has recorded the multiple flute parts. Original videos of water have been created from locations around Nova Scotia.

3. Morphing Topographies

the epipelagic zone sits just under the surface of the water
the sun and the moon are hazy spheres from above

the mesopelagic zone sits a little further down
where life abounds and the water is plentiful

the bathypelagic zone is the stuff of legend
myths abound and the creatures are fantastical

the abyssopelagic zone is dark and cold
the pressures are severe and life is few and far between

the hadopelagic zone is crushing … crushing ... crushing!

4. Water Is …

water is one and all
water is us
