Longplayer is a one thousand year long musical composition. It began playing at midnight on the 31st of December 1999, and will continue to play without repetition until the last moment of 2999, at which point it will complete its cycle and begin again. Conceived and composed by Jem Finer, it was originally produced as an Artangel commission, and is now in the care of the Longplayer Trust.
How does Longplayer work?
Early calculations made while trying to establish the correct increments. At the bottom is an estimation of the playing positions on the 7th of January 2000 based on these values.
The composition of Longplayer results from the application of simple and precise rules to six short pieces of music. Six sections from these pieces – one from each – are playing simultaneously at all times. Longplayer chooses and combines these sections in such a way that no combination is repeated until exactly one thousand years has passed. At this point the composition arrives back at the point at which it first started. In effect Longplayer is an infinite piece of music repeating every thousand years – a millennial loop.
The six short pieces of music are transpositions of a 20’20” score for Tibetan Singing Bowls, the ‘source music’.[1] These transpositions vary from the original not only in pitch but also, proportionally, in duration.[2]
Every two minutes a starting point in each of the six pieces is calculated, from which they then play for the next two minutes. Each starting point is calculated by adding a specific length of time to its previous starting point.[3] For each of the six pieces of music this length of time is unique and unvarying. The relationships between these six precisely calculated increments are what gives Longplayer its exact one thousand year long duration.
Rates of Change
In the diagram below, the six simultaneous transpositions are represented by the six circles, whose circumference represents the length of the transposed source music. The solid rectangles represent the two minute sections presently playing. The unique increments by which these six sections advance determine their respective rates of change. These reflect different flows of time, from a glacial crawl to the almost perceptible sweep of an hour hand. The incremental advance of the third circle, is so small that it will take the full thousand years for it to pass once through the source music. Conversely the increment for the second circle is such that it makes its way through the music every 3.7 days. The diagram updates every 2 minutes

The Library of Babel is a place for scholars to do research, for artists and writers to seek inspiration, for anyone with curiosity or a sense of humor to reflect on the weirdness of existence - in short, it’s just like any other library. If completed, it would contain every possible combination of 1,312,000 characters, including lower case letters, space, comma, and period. Thus, it would contain every book that ever has been written, and every book that ever could be - including every play, every song, every scientific paper, every legal decision, every constitution, every piece of scripture, and so on. At present it contains all possible pages of 3200 characters, about 104677 books.
Since I imagine the question will present itself in some visitors’ minds (a certain amount of distrust of the virtual is inevitable) I’ll head off any doubts: any text you find in any location of the library will be in the same place in perpetuity. We do not simply generate and store books as they are requested - in fact, the storage demands would make that impossible. Every possible permutation of letters is accessible at this very moment in one of the library's books, only awaiting its discovery. We encourage those who find strange concatenations among the variations of letters to write about their discoveries in the forum, so future generations may benefit from their research.
