Doctor Who show, as the story begins anew with each companion and she undergoes more change than the Doctor. The primary companions of the Ninth and Tenth Doctors were Rose Tyler (Billie Piper), Martha Jones (Freema Agyeman), and Donna Noble (Catherine Tate) with Mickey Smith (Noel Clarke) and Jack Harkness (John Barrowman) recurring as secondary companion figures. The Eleventh Doctor became the first to travel with a married couple, Amy Pond (Karen Gillan) and Rory Williams (Arthur Darvill), whilst out-of-sync meetings with River Song (Alex Kingston) and Clara Oswald (Jenna Coleman) provided ongoing story arcs. The tenth series introduced Pearl Mackie as
Music of the Spheres (Doctor Who) admiring composer Giacomo Puccini; and the Ninth Doctor dancing with Rose Tyler to "In The Mood" by Glenn Miller in "The Doctor Dances". In writing the episode, Davies expressed hope that "this mini-adventure [would show] that music can take any shape or form, whether it’s singing, or playing the recorder, or even the spoons." He states that "music can go anywhere, reach anyone, and make better people of us all. Just like the Doctor." The mini-episode was filmed on Saturday 3 May 2008, the last day of filming for Series 4 of "Doctor Who", in the BBC Wales studios at
