[Queequeg]

Ever feel that you are rushing a piece as you play it? Many musicians are troubled by this.
Well, take a tip from John Cage.
The slowest musical composition in the world is As Slow as Possible (ASLSP) by American avant-garde composer John Cage.

The 639-Year Performance
The Rule: John Cage wrote the score in 1987 with the simple instruction to play it "as slow as possible".
The Location: A continuous performance is currently underway on a specially built, automated organ at the St. Burchardi church in Halberstadt, Germany.
The Timeline: The performance began on July 5, 2001, and is scheduled to end 639 years later on September 5, 2640.
Note Changes: Individual chords or notes are held for months or even years at a time before the mechanical organ shifts to the next sound.
