"Seeking The Doctor"
From Tardis Wiki, the free Doctor Who reference
"Seeking the Doctor" is a piece of music composed by Murray Gold for Doctor Who. It served as a secondary motif for the Ninth Doctor, the Tenth Doctor, and the TARDIS. It first appeared in the series 1 episode, Rose, as Rose searched the internet for clues about the Doctor. It later appeared in the series 2 episodes, School Reunion and "Love & Monsters", when Sarah Jane and Elton found the TARDIS, respectively, and in "Army of Ghosts" when Yvonne and Matt see the TARDIS in the CCTV network. Its final use was in the Series 4 episode, "The Stolen Earth", as Wilfred convinced Sylvia to open her mind to the possibility of extra-terrestrial life.
