The Moonlight Sonata was a celebrated musical piece written by Ludwig van Beethoven.
The Cyberman Bremm, known to the public as the Silver Turk, played it on the piano at the 1873 Vienna Exposition. His 5 o'clock performance on the 11 September was interrupted by the Doctor during adagio sostenuto. (AUDIO: The Silver Turk)
Behind the scenes Edit
None of the stories identify the name of the piece, but the famous adagio sostenuto, the first movement of the sonata, is clearly recognisable in each.
