Aquasphere was composed in 1990. Much like an aquatic world, it is built upon multiple layers and textures -- in this case, translated into sounds and musical motifs. Although not a “minimalist” work, Aquasphere does utilize several repetitive motifs which suggest the ebbing and flowing of the tide. And certain effects are employed that simulate various sounds of the sea.

Aquasphere received its premiere performance at Abilene Christian University (Abilene, TX), and has subsequently been featured during the Electric Mountain Music Festival held at Central Wyoming College, the 1994 Bates New Music Festival at Bates College (Lewiston, ME) and the 1995 National Conference of SEAMUS (Society of Electro-Acoustic Music in the U.S.) held at Ithaca College (Ithaca, NY).

Aquasphere was realized and recorded in the Pizers’ home studio utilizing the following equipment: Yamaha Clavinova electronic piano (controlling keyboard), two Kawai K-1m synthesizer modules, Kurzweil K-1000 keyboard synthesizer, Yamaha EMT-10 synthesizer module, Kawai MX-8R mixer, Alesis Quadraverb sound processor, and Macintosh computer with Mark of the Unicorn Performer sequencer software (plus Sony DAT recorder).
