Subtract 1361 from the millennial year 2000, and the result ist 639. So one can say that the cradle of modern music was in Halberstadt. This organ was the first of its kind with a claviature of 12 notes, and this claviature is used on our keyboard instruments today. Michael Praetorius, a composer and important theorist of music of the late 16th and early 17th centuries, wrote that an organ with the first modern keyboard arrangement had been built in Halberstadt's cathedral in 1361. Aside from tone changes as determined by the organ piece, further events are taking place in the course of the organ project. The Halberstadt Cage concert, which fascinates people all over the world, is being accompanied by many additional events and has proved to be a point of attraction wholly in the open spirit of John Cage. What at first seemed to be only an utopian idea developed very quickly into an impressive and innovative art project generating a widespread interest. The performance began on 5 September 2001, the 89th birthday of the avant-garde composer and artist John Cage, with a seventeen month-long pause before the first tone of the organ, especially built for the performance of this piece, was to be heard. The longest music piece in the world is being performed in the city of Halberstadt in Germany: John Cage's composition for organ ORGAN2/ASLSP - As SLow aS Possible - is resounding here in an extreme interpretation of 639 years, that means until the year 2640! Halberstadt is a town (43,800 inhabitants in 2015) in the German state of Saxony-Anhalt, and the capital of the district of Harz.
