00:00:00 1 January 2025 at the International Date Line marks 25 years since the beginning of Longplayer (
@_longplayer_ ), a thousand-year long composition by Jem Finer. The core of the piece is a set of instructions that generate slowly-changing phase relationships between six musical layers, finally returning to their original alignment at the end of 2999. The piece plays continuously in the lighthouse at
@trinitybuoywharf , in London’s Docklands.
Given that the duration of the piece spans way beyond our lifetimes, it creates questions around long-term sustainability and “deep time”. How is stewardship of the work passed along into the future? How can we create human structures of care that endure over many generations?
It also raises questions of digital longevity. I’ve been working with Jem and the Longplayer Trust in considering the long-term future lifespan of the project, and how it can be technically implemented to maximise its sustainability and transmissibility to future generations.
One of the outcomes is a new open-source implementation of the Longplayer algorithm, written in Python and running on the open
@raspberrypi platform. It uses GPS synchronisation to obtain a time signal to sub-microsecond accuracy, for accurate long-term timekeeping even in remote locations where internet time servers are not available. Accompanying this is an instruction score and lexicon for the piece, inviting new implementations of technical or non-technical natures.
Both are available on The Longplayer Trust GitHub: /thelongplayertrust
The Longplayer listening post at
@trinitybuoywharf itself has been re-curated and refitted for its 25th birthday by Jem, James Bulley and the Longplayer Trust team, produced by
@imogenfree , with a permanent new 6-channel spatial installation architected by
@simonchendry , technical production by
@richard_hards and
@dont.bother222 . It was lovely to see the whole team gather there at noon today to mark the new year with a reflection on the longer-term future.
