Slow music: Chord change in Germany of 639-year organ piece
HALBERSTADT, Germany — Hundreds of fans attended a special kind of musical happening Saturday at a church in Germany: a chord change in an organ piece that is supposed to last for an entirety of 639 years.
The performance of the “ORGAN/ASLSP,” or As Slow As Possible, composition began in September 2001 at the St. Burchardi Church in the eastern town of Halberstadt and is supposed to end in 2640 — if all goes well.
The music piece by the American composer John Cage is played on a special organ inside the medieval church. The last sound has been the same one for the last six years and 11 months, and therefore the chord change Saturday was a big event among fans of the John Cage Organ Project.
A chord change means that the sound of the organ pipes changes either because new sounds are added or existing sounds end. On Saturday, two new organ pipes were added.
