"These pieces [Tenzone and Trio] are in one movement and utilize similar sonic vocabulary and coloristic devices. They are strikingly beautiful compositions that employ delicate textural and timbral effects. Structurally they grow from carefully shaped fragments into phrases and longer lyric gestures that relate sectionally."
"Chester Biscardi's 'Tenzone' for two flutes and piano (1975) explored the effects of superimposing sustained flute tones of various timbres and texture. It was an absorbing experiment, especially when Mr. Biscardi contrasted the throbbing friction of intervals with the icy concord of intervals of a third."
"Tenzone for two flutes and piano by Chester Biscardi (Presser/Universal) is a brooding piece, mainly of slow harmonic movement. It uses complex rhythmic figurations and a wide variety of new techniques, including harmonics for all three instruments and multiple sonorities for the flutes. The sections of fast flourishes, whose contrast with the basically slow tempo creates the tension of the title, are tantalizingly short-lived."
"Tenzone, by the young Wisconsin-born composer Chester Biscardi, is a nine-minute work in one movement for two flutes and piano. Dedicated to Toru Takemitsu, with whom Biscardi studied at Yale University, it exudes a Japanese character with its opening very Shakuhachi-like sounds. The cool, static feeling that predominates is interrupted by several unmetered passages marked "as fast as possible," which are especially effective. Notable, too, is the understated role of the piano, whose brief appearances add nice delicacy and texture."
"This writer sees Biscardi's Tenzone as a music of sonorous curves, of neoimpressionism interfacing complex rhythms, plus decorative and elegant timbres. These include a variety of vibratos, key clicks, microtones, and multiphonics, as well as piano harmonics. There is contrastive constancy and there is magnificent sonorous realization.
[Of] the three early works . . . Tenzone (1975) . . . is the most conventional, with elegant sonic strands interweaving between the flutes with periodic interjections from the piano, which acts as more of a guide than a full-fledged participant.
Tenzone, for two flutes and piano (composed in 1975), is a response to Takemitsu's 1959 Masque, for two flutes. Both it and At the Still Point, for orchestra and trio (1977), utilize the technique of "frozen registration." Harmonies don't logically flow from one moment to the next, leaving the listener not unpleasantly trapped in a never-ending present tense. Like Debussy, Biscardi uses instrumental timbre and dynamic variation as structural elements.
Chester Biscardi's affinity for the flute was established in his Tenzone for two flutes and piano. Given Biscardi's ear for timbre, his careful, caring use of harmonics to veil and unveil pitches, and his extraordinary writing for piano, asking him for a flute and piano work was the natural next step. Traverso, his NFA-commissioned piece (1987, Young Artist), lives up to the highest expectations. It's a truly significant work that I would love to see move into the core flute and piano repertoire. I've performed it to enormous audience response.
