Do you know the piece of music that takes the longest time to play in the world?
It is a pipe organ piece called "ASLSP (As Slow as Possible)" composed by John Cage.
This piece is meant to be played as slowly as possible, and it is said to take 639 years to perform.
The performance started in 2001 as a grand project at a monastery in Halberstadt, Germany. "ASLSP" teaches us a new aspect of music. Normally, music is completed in a few minutes to a few hours, but this piece progresses on a time scale beyond that.
The audience, who waits for the changes in sound that come every few years, can gain a new perspective on the relationship between music and time by being present at those moments. The piece raises the philosophical question, "What is time?" Music that moves on a different scale from the flow of time we feel in our daily lives makes us think about the concept of time.
It goes beyond just music and presents us with a new form of time and sound.
