Gliss Glass

None Gliss Glass is an original instrument consisting of a series of custom glass vessels of various sizes, filled with water, interconnected by a system of tubes and valves. Though much larger than a wineglass, the instrument is played in much the same way, by running a wet finger or hand around the rim. The glass vessels are lightly amplified to pick up subtle squeaks, sloshes and scrapes.

The musician controls the water level and flow through the instrument by manipulating the valves and vessel heights. As water drains or fills a glass vessel, the frequency rises or falls respectively. By making use of the basic principle of hydraulic equilibrium, the instrument creates naturally slow, shifting glissandos.

Gliss Glass was created during a residency at the Akademie Schloss Solitude in Stuttgart, Germany, 1997-98, and debuted by Bel Canto at the Internationale Ferienkurse für Neue Musik, Darmstadt, 1998.

Krystyna Bobrowski : Composer, musician and sound artist
Krystyna Bobrowski is a composer, musician and sound artist. She designs and builds her own instruments using natural materials and everyday objects, often modifying an object’s sound through physical manipulation and/or the use of electronics. The sounds of rocks and rocking chairs, seaweed and wine glasses, twigs and motors, leaves and water-filled tubes have all found their way into her pieces. Bobrowski is most known for the Gliss Glass, an original instrument consisting of a series of custom glass vessels of various sizes, filled with water, and interconnected by a system of tubes and valves.

In addition to performing her own work, she has performed and recorded the pieces of other composers including David Behrman, Anthony Braxton, John Cage, Alvin Curran, Lou Harrison, Larry Polansky, Wendy Reid and Christian Wolff. She has performed a number of times with the Merce Cunningham Dance Company and continues to collaborate with musicians in the Bay Area improvised music community. She performs and collaborates extensively with the improvisation ensemble Vorticella: Erin Espeland, Brenda Hutchinson and Karen Stackpole.
Bobrowski received her M.F.A. in Electronic Music and Recording Media from Mills College and her B.A. in Computers and Music from Dartmouth College where she first met and studied with Christian Wolff. She lives in Oakland, CA and teaches at the College of San Mateo (CSM) where she instituted the CSM Electronic Music Program. She has been an artist-in-residence at the Exploratorium, San Francisco, CA, Headlands Center for the Arts, Marin, CA and the Akademie Schloss Solitude, Stuttgart, Germany. Her scores are available through Frog Peak Music, a composers’ collective.
