Die Zeit has issued a charming video in which three brass players from the Berlin Konzerthaus Orchestra, led by Helge von Niswandt, give a mock-solemn demonstration of the musical properties of the vuvuzela. They do their level best with the chorale theme from Brahms's First Symphony — "the famed vuvuzela chorale" — and a bit of Ravel's Boléro.
Update: Now available with English subtitles.
