Stockhausen’s ‘Freude,’ by Chamber Music Society

From NYTimes.com:

Karlheinz Stockhausen conceived his final masterpiece, “Klang” (“Sound”), as a daylong event of both sprawling scale and surprising intimacy. “It seems that I am listening again more for moments, atmospheres,” he said of the project, “rather than formulas.”

He could have been speaking for much of the music from the past 50 years, which achieves its effects through details and mood — those moments and atmospheres — rather than from broad allegiance to systems like serialism. He imagined what he called the 24 “musical moments” of “Freude” (“Joy”), the second hour of “Klang,” as a day within the work’s larger day.
