Doctor Who is well known for its theme. The original signature track was created by Delia Derbyshire and Ron Grainer at the BBC Radiophonic Workshop, and it had the most beautiful yet haunting sound to it at the same time. There was no face in the opening credits in the beginning. The series wouldn't do this until Patrick Troughton took over as the Doctor in 1966. Frankly, the face is what makes the theme what it is as well, not just the music. Throughout the years, the music and background has changed and so have the faces. From 2005 until 2011 there were no faces in the theme sequence. Until 2012, assuming because the 50th anniversary was coming up, Steven Moffat and the production team decided to bring back the Doctor's face. Some of the newer fans thought this theme sequence was horrid, while the classic fans squealed with glee just to see the face back in the opening credits. Of course everyone has their own ideas of which versions are the best, but there are some out there fans can agree on. Here are just a few of the theme sequences that were used in the program, and these five listed are probably the most notable ones. Simply because they changed the show in some way. There are quite a few theme sequences out there and not all could make the list. Not because they weren't good at all, but some stood out a bit more so than the others.
