"Music of the Spheres" is an interactive mini-episode of the British science fiction television series Doctor Who that premiered at the Royal Albert Hall in London before the Intermission of the Doctor Who Prom on 27 July 2008, for which it was especially made. The Doctor Who Prom, including the audio for "Music of the Spheres", was broadcast simultaneously on BBC Radio 3. "Music of the Spheres" was shown on the official BBC Doctor Who website during the interval and the concert itself was filmed for later broadcast on BBC One on 1 January 2009.The episode has live and pre-recorded components: the pre-recorded component takes place in the TARDIS; the live component is the Doctor Who Prom which took place during the episode's first transmission. Consequently, a major component of the episode is that it breaks the fourth wall: the Doctor (David Tennant) "converses" with the audience and conducts the orchestra to perform his symphony Ode to the Universe. He is antagonised by the Graske (Jimmy Vee), who intends to cause mischief at the Prom.
