Alan
Turing (1912-1954) was the brilliant British mathematician
who is widely recognized as the father of the modern
computer at the University of Manchester, having
demonstrated its theoretical possibility in what is known
as the Turing machine. He also became famous after his
death when his role during World War II in deciphering the
German “Enigma” code that was key to the British war
effort in the Atlantic finally became publicly known.
The composer's work Enigma is an unstaged but dramatic rendition of two key periods in Turing’s personal life, the first from his early years when he became infatuated with the brilliant Christopher Morcom who died young, and the second from his final years when he was convicted of gross indecency (as was Oscar Wilde more than a half century earlier) because of a homosexual liaison and eventually appears to have committed suicide. In between these two sections is a piano and multi-channel soundscape piece From The Unseen World based on the digitally processed “Christopher arpeggio” which turns it into an ethereal swirl of harmonics, the title being a phrase of Turing’s to refer to the spirit dimension – and by extension to Christopher. The pitches that are not part of the arpeggio are heard in a bell-like chord that symbolizes the real world.
The composer assembled the libretto from Turing’s life and words, including a section of Tennyson’s In Memoriam, and the piece begins with a poem written by a 15-year old Manchester student, Hallie Fletcher, in 2010 in response to Turing’s life. Video recorded dancer: Hans Seidemann; audio recorded baritone: Michael Mori. Audio spatialization with the SoundHub, produced by Outboard Inc (UK).Enigma was premiered during the Mantis Festival at the University of Manchester (where Turing worked at the end of his life) by William George and Barry Truax at a Turing tribute concert during the on October 28, 2012.
An earlier staged version of the
two Turing scenes (for 3 singers and dancer) was
commissioned by Vancouver New Music with the assistance of
the Canada Council, and premiered in Vancouver in
November, 2010.
From The Unseen World can also be
performed independently. See also the article in Musicworks.
