Klang (Stockhausen)
Klang (pronounced [klaŋ]), also known as The 24 Hours of the Day (German: Die 24 Stunden des Tages) is a cycle of compositions by Karlheinz Stockhausen, on which he worked from 2004 until his death in 2007. It was intended to consist of 24 chamber-music compositions, each representing one hour of the day, with a different colour systematically assigned to every hour.
