A Musical Performance Lasting 639 Years

The musical piece As Slow as Possible is currently being performed in a church organ in Germany, with a scheduled duration of over six centuries. It plays at such an incredibly sluggish tempo that a single chord change can take years.

The performance began in 2001 and is designed to last until the year 2640. Because the score is played at the slowest possible speed, listeners may hear the exact same note for months or even years at a time. The organ was specifically modified with extra pipes to accommodate the unique requirements of this extreme duration. It serves as a fascinating meditation on the nature of time and our human perception of art.
