As Slow as Possible
Organ²/ASLSP (As SLow aS Possible) is a musical piece by John Cage and the subject of one of the longest-lasting musical performances yet undertaken. It was originally written in 1987 for organ and is adapted from the earlier work ASLSP 1985; a typical performance of the piano version lasts 20 to 70 minutes. In 1985, Cage opted to omit the detail of exactly how slowly the piece should be played.
The piece was commissioned for a piano competition by The Friends of the Maryland Summer Institute for the Creative and Performing Arts as a contemporary requirement. Cage employed an open format mainly to ensure that no two performances would be the same, providing the judges a break from the monotony of most compositions. The score consists of eight pages.
On February 5, 2009, Diane Luchese performed "Organ²/ASLSP" from 8:45 AM to 11:41 PM in the Harold J. Kaplan Concert Hall at Towson University. This 14 hour-and-56-minute performance, in strict adherence to the score's temporal proportions, is the longest documented performance of the piece by a single person so far, although a full 24-hour performance of the original piece, ASLSP, was given by Joe Drew during the ARTSaha! festival in 2008. Drew has also given 9- and 12-hour performances of the piece, and is planning a 48-hour performance.
On September 5, 2012, as part of John Cage Day at the University of Adelaide, Australia, Stephen Whittington performed an 8-hour version of ASLSP on the Elder Hall organ. The eight sections of the work were each allocated an hour, with each section divided into segments of one minute, within which the precise timing of events was left open. In performance, seven sections were played, with one omitted and one repeated. Organ registrations were determined by chance procedures.
A 1997 conference of musicians and philosophers discussed the implications of Cage's instruction to play the piece "as slow as possible", given that an organ imposes virtually no time limits. A project emerged to perform the piece for 639 years. A pipe organ that has been properly maintained has no finite lifespan; the duration was chosen to commemorate the first documented permanent organ installation, in 1361 in the cathedral of Halberstadt, 639 years before the proposed start date of 2000.
An organ built specifically for the performance was completed in 2009. It stands in the right transept of the Burchardi Church, with the bellows in the left. Between January and May 2005, it contained only six pipes. Because the instrument sounds constantly, there is a cube of acrylic glass around it to reduce the volume.
The performance commenced in the St. Burchardi church on September 5, 2001, with a pause lasting until February 5, 2003. The first chord was then played until July 5, 2005. The chord consisting of A above middle C, C above middle C and the F♯ above that (A4-C5-F♯5) began sounding on January 5, 2006, and concluded on July 5, 2008. That sonority can be heard on a website devoted to the Halberstadt event.
The latest sounding chord is (C4-A♭4). On July 5, 2008, the weights holding down the organ pedals were shifted resulting in the 6th chord change. Two more organ pipes were added alongside the four already installed and the tone became more complex at 15:33 local time. The bellows provides a constant supply of air to keep the pipes playing.
The note change of January 5, 2006 takes place at 8:36 in this audio clip.

The performance is scheduled to end on September 5, 2640.
The piece started with a 17-month rest on September 5, 2001, Cage's 89th birthday. The first sound appeared on February 5, 2003. Subsequent dates for note changes include:
