In his compositions, Jay Schwartz (born in California, now living in Cologne) works with the aspects of the physics of sound and utilizes tonality in the context of the physics of organic harmony, making use of the overtone spectrum, microtonality, and glissandi in a poetic context with a captivating sensuous drawing power and an unabashed emotional disposition. Schwartz integrates these acoustical events in a clear, deliberately prolonged, coherent form, which generates a persistent metamorphosis as well as a conscious dramatic plan. Schwartz's homogeneous instrumentations, as in "Music for Orchestra" for string orchestra, uphold his ideas of clarity, simplicity and of organic sound.
