Feldman's canvas contains sparse, isolated tones and commentary in an environment of heightened concern. (Concern negates the idea that Feldman's music embodies an existential void.) Concern creates tension, energized by the composer's sense of responsibility, and desire. The music sounds familiar at times, where a motif occurs and is not forgotten, but returns in another place in another guise. Or multiple motifs (each instrument's personal statement) are reassembled into something resembling something else, or only itself. Even Feldman's repetition is never exact, as there are slight shifts in weight, shade, density, intensity. And when, eventually, the music ends, it just ends, for no need, or reason, with no explanation, no answers.
