'Longplayer' by Jem Finer

Part of the 'Longplayer Live' instrument.

Within Trinity Buoy Wharf Lighthouse is a unique musical experience. A musical composition, entitled 'Longplayer', that will play for 1,000 years.

On the first floor you can walk around part of the 66-foot-wide orchestral instrument, which is used to perform 'Longplayer Live', while listening to 'Longplayer' being streamed into the room.

However, the Lantern Room, at the top of the Lighthouse, is the best place to hear 'Longplayer', while taking in the unique views on offer.

'Longplayer' has been running since the year 2000.

What is 'Longplayer'?

'Longplayer' is the brainchild of Jem Finer and is a 1,000-year-long musical composition that has been playing continuously since the first moments of the year 2000. It is designed to play on, without interruption and repetition, until the last moments of 2999.

Since it began, 'Longplayer' has been performed simultaneously by a number of computers around the world - from its primary location at Trinity Buoy Wharf Lighthouse to listening posts in Alexandria, Brisbane and San Francisco. It can also be heard anywhere in the world via an online audio stream at Longplayer.org.

Singing Bowls.

How does it work?

Composed by Jem Finer, 'Longplayer' is written for a set of highly resonant 'Singing Bowls', an ancient type of standing bell. These bells are sounded according to a precisely timed score, itself based on six simple algorithms. The resulting music is made up of six continuous, interlocking musical patterns whose harmonic and rhythmic interactions change gradually over hours, days, decades and centuries.

Bow Creek Lighthouse: London's Only Lighthouse

On the Leamouth Peninsula, where the River Thames and Bow Creek meet, lies Trinity Buoy Wharf, in the London Borough of Tower Hamlets.

The site was used by the Brethren of Trinity House, now known as Corporation of Trinity House, from 1803, with the sea wall being constructed in 1822.

Originally there were two lighthouses, with one being built in 1852, by James Walker, and the other between 1864-1866, by James Douglas. The former was demolished in the 1920s, while the latter one still stands today.

Both lighthouses were used to train lighthouse keepers and for testing lighting systems, not for their true purpose, as the River Thames is not that dangerous a stretch of water.

The original lantern, at the top of the lighthouse, came from the Paris Exposition of 1867, where Trinity House had demonstrated improved systems of electric lighting for lighthouses.

Michael Faraday set up a workshop, next door to the lighthouse, and carried out experiments here, discovering the principles underlying electromagnetic induction, electrolysis and diamagnetism.
