Toccata and Fugue in D minor

The Toccata and Fugue in D minor was a composition for organ. When the Sixth Doctor temporarily fixed the TARDIS' chameleon circuit, the TARDIS became a pipe organ, and the Doctor played the first phrase of the Toccata and Fugue in D minor on its keyboard. (TV: Attack of the Cybermen)

Behind the scenes

 * The piece is not actually named in Attack, but is famous enough to be immediately and uncontroversially recognised.
 * The incidental music for the film Daleks' Invasion Earth 2150 A.D. includes a jazzy variation on the Toccata and Fugue in D minor.
