Moonlight Sonata
From Tardis Wiki, the free Doctor Who reference
The Moonlight Sonata was a celebrated musical piece written by Ludwig van Beethoven.
The Sixth Doctor attempted to play it on the piano before stumbling and giving up, regretting turning down Elton John's lessons. (AUDIO: Project: Lazarus)
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)
The composition played in 2007 on John Ellis' 1950s radio; John smiled at the tune. (TV: Out of Time)
Behind the scenes
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.
