Longest Compose , Organ² / ASLSP
It all started in 2001 and an interesting compose started to ring in a church in Germany , the most interesting part is this music will continue and finish itself in 640 years.
The real name of this compose is organ²/aslsp composed by John Cage . If you wonder what aslsp means , don't worry It means as slow as possible. John Cage costomized the original music "Aslsp 1985" to pipe organ and he aimed to make the worlds longest music performance to making it a lot slower.This weird song started to play in 2001 will end in St. Burchardi Church in 2640.
You may ask that why it is 639 years ? . When they were deciding the lenght of the song , they noticed the perfectly working Organ pipe in the Halberstadt Catedral and they said that ours can stay in shape for 639 years too and they built a new enstrument.
If you wonder how it is looks or sounds like you can watch from here.
The performance started in 5 September in 2001. However because of the "pause" died the music didn't start untill 5 february 2003 , first notes started to ring in 5 June 2005 and the notes were A , above middle C , C above middle c and F Sharp.
The notes changed in 5 January 2006 and it continues as a4-c5-fsharp5 untill 5 june 2008. This continued for a while and the last note change happened in 5 september 2013 , and the other change is expected in 2020.
