Ode to the Universe

Ode to the Universe is a short, discordant piece of classical music composed by the Doctor.

Inspired by the "music of the spheres", the natural sound of the universe as heard through the TARDIS' harmonic filters, the piece received its debut at the 2008 Proms at Royal Albert Hall when, due to a rift in time and space, the Doctor was briefly able to communicate with a proms concert in progress.

The Doctor conducted the performance of the piece, which sounded similar to that of an orchestra tuning their instruments, and was pleased with the results. A Graske that was aboard the TARDIS at the time used the distraction caused by the playing of the piece to slip through the portal and briefly cause havoc with the audience.

Behind the scenes

 * The canonicity of Music of the Spheres has not been established.
 * Although it's been hinted at that the Doctor has played a role in the composition of other, more famous songs, this is one of the only occasions in which he has claimed direct credit for composing a piece of music.
