The song that played once—and vanished forever
Trivia of the Day
What is the longest piece of classical music ever composed?
- Wagner's 'Ring Cycle' at 15 hours
- Satie's 'Vexations' at 18+ hours of repetition
- John Cage's 'Organ²/ASLSP' at 639 years
- Philip Glass's 'Einstein on the Beach' at 5 hours
Answer: John Cage's 'Organ²/ASLSP' at 639 years — The performance began in 2001 and won't finish until 2640—the organ has played only 13 note changes so far.
In a church in Halberstadt, Germany, an organ plays a single composition that will take more than six centuries to complete. John Cage's "As Slow as Possible" is being performed on a specially built organ at a tempo so glacial that individual notes last for months or even years. The performance began on September 5, 2001, with seventeen months of silence—because Cage's score opens with a rest.
Cage originally wrote the piece in 1987 for piano, intending it to last about 20 to 70 minutes depending on the performer's interpretation of "as slow as possible." But when organizers in Halberstadt decided to stage it on the organ in St. Burchardi church, they took the title literally and asked: what is the slowest possible tempo? They settled on 639 years, matching the age of the church's previous organ when the project began.
The performance is sustained by a system of weights and electric blowers that hold down keys for extended periods. When a note change occurs—sometimes after years—it becomes a minor cultural event, drawing visitors from around the world. The last change happened in February 2022; the next is scheduled for 2026. By the time the final chord sounds in 2640, the world will have turned over roughly 25 generations.
The project embodies Cage's philosophy that music exists in time and silence as much as in sound. It challenges our human-scale perception of duration and permanence, turning a composition into a living monument that will outlast everyone alive today. In an age of instant streaming and three-minute pop songs, "Organ²/ASLSP" is a 639-year meditation on patience itself.

Dark, shadowy, or obscure; shrouded in darkness. From the Latin tenebrae, meaning "darkness" or "shadows," the word carries a Gothic weight often used to describe both literal gloom and metaphorical obscurity—moral ambiguity, hidden intentions, or knowledge veiled in mystery.

This Day in History
1508 — On August 11, 1508, Michelangelo reluctantly began painting the Sistine Chapel ceiling, a commission from Pope Julius II that the sculptor initially resented—he considered himself a sculptor, not a painter, and suspected rivals of engineering the assignment to humiliate him. The project would consume four years of his life, requiring him to work on scaffolding in painful contorted positions, paint dripping into his eyes. The result, of course, became one of humanity's supreme artistic achievements, containing over 300 figures including the iconic "Creation of Adam." Michelangelo's reluctant masterpiece redefined what painting could be and established the ceiling as a pilgrimage site for artists ever since.
