This organ will play one composition until 2640. It's redefining how slowly music can be played
- A small organ in Halberstadt, Germany, has been playing a piece by composer John Cage at a very slow pace for nearly 25 years.
- On August 5, 2026, a rare chord change marked the completion of about 4% of the 639-year John Cage Organ Project.
- The performance began on September 5, 2001, and is scheduled to finish on September 4, 2640.
- The project features a continuous sound created by an electric-powered blower system and involves manual chord changes.
- The recent chord change added an eighth pipe to the organ, changing the sound experienced by the audience.
A small organ in eastern Germany is the headliner of the world’s slowest concert. It has been playing the same piece of music by composer John Cage at a glacial pace for nearly 25 years.
A rare chord change on Wednesday — from seven notes to eight — represented the completion of about 4% of the 639-year endeavor of the John Cage Organ Project Halberstadt. The composition, called “ORGAN²/ASLSP (As SLow aS Possible),” is scheduled to finish on September 4, 2640.
The performance began on September 5, 2001, with a silent pause that lasted until February 5, 2003, when the first chords could actually be heard. An electric-powered blower system sends wind into the organ to create a continuous sound, and chord changes are done manually.
More than 150 people attended the recent chord change event, with many listening to the new sound that was created by adding an eighth pipe to the organ. The project has transformed the Burchardi Church, which was largely in ruins before the initiative began.
这台风琴将演奏一首作品直到2640年，重新定义音乐的缓慢演奏方式
德国东部的一台小风琴是世界上最慢音乐会的主角。它已经以极其缓慢的节奏演奏约翰·凯奇的同一首音乐作品近25年。
周三的罕见和弦变化——从七个音符变为八个音符——标志着639年约翰·凯奇风琴项目完成了约4%。这部作品名为“ORGAN²/ASLSP（尽可能慢地演奏）”，计划于2640年9月4日完成。
演出于2001年9月5日开始，最初有一段静默，直到2003年2月5日才可以听到第一声和弦。电动鼓风机系统向风琴送风以创造持续的声音，和弦变化则是手动完成的。
最近的和弦变化活动吸引了超过150人参加，许多人聆听了通过为风琴增加第八根管子而产生的新声音。该项目改变了布尔查尔迪教堂的面貌，之前该教堂大部分处于废墟状态。
