Organ2/ASLSP (As Slow as Possible) is considered the world’s slowest musical composition and the subject of the longest-lasting musical performance in recorded human history.
Written by the late American composer John Cage, As Slow as Possible has been playing at the St. Burchardi church in Halberstadt, Germany since September 5, 2001. ‘Played’ is perhaps to strong a word to describe the sound coming out of the organ built specifically for this musical piece, as the performance began with a pause that lasted until February 2003, and has since continued with single notes played continuously for several months, sometimes years. For example, the latest note change occurred on September 5, 2020, and the next one is scheduled for February 5, 2022. I think it’s safe to say that none of us will hear the end of this epic performance, as it is meant to end in the year 2640…
