位于德国哈尔伯施塔特布尔卡迪教堂的一台风琴正在演奏美国作曲家约翰·凯奇的作品《ORGAN²/ASLSP》。[1]该项目自2001年9月5日开始，首先进行了长达近两年的沉默，直到2003年2月5日才听到第一个和弦声音。[1]整个演奏计划持续639年，将在2640年9月4日完成。[1]
周三，风琴进行了第17次和弦变化，音符从7个增加到8个，标志着这个超长项目已完成约4%的进程。[1]下一次和弦变化定于2027年10月5日进行。[1]项目方已开始销售2640年9月4日最终演出的门票，价格定为2640欧元（约3045美元）。[1]根据评估，该风琴的管道预计能再使用至少500年，足以支撑整个演奏周期的完成。[1]
An organ in Halberstadt, Germany is performing John Cage's "ORGAN²/ASLSP," a composition designed to unfold over 639 years, concluding in 2640.[1] The project commenced on September 5, 2001—what would have been Cage's 89th birthday—beginning with nearly two years of silence before the first actual chord sounded on February 5, 2003.[1] On Wednesday, the organ underwent its 17th chord change, transitioning from seven to eight notes, representing approximately 4% completion of this extraordinary musical undertaking.[1]
The next scheduled chord alteration is set for October 5, 2027.[1] The initiative has begun selling tickets for the final performance on September 4, 2640, priced at 2,640 euros, equivalent to approximately 3,045 dollars.[1] The organ's pipes are expected to remain functional for at least another 500 years, well beyond the composition's completion date.[1] Cage was born in Los Angeles in 1912 and died in New York in 1992.[1]
