Kaleidoscope for Two Pianos was written during my student years as an undergraduate at Columbia College (1955–59). The work began as a project in Otto Luening’s composition class, and is dedicated to Luening and to composer Marc Bucci. As the title implies, is a colorful mosaic of changing symmetrical patterns, some infused with a ragtime feel, others highly lyrical in content. The work is in ternary form with an extended lyrical center that treats a folk-like melody to a variety of contrapuntal elaborations. In general, Kaleidoscope is high-spirited and full of the energy of youth.
