With Peter Capaldi about to take his final bow as everyone’s favorite time traveler, much is ado about the next actor to play the Doctor being female: Jodie Whittaker of Broadchurch fame. Some fans (this writer included) are saying "It's about time!" (get it?) while others aren't so keen on the break with tradition.
This begs pointing out that while the iconic theme music was scored with pen and paper by Ron Grainier (also composer of the theme to The Prisoner), it was a woman who arranged it and orchestrated it into the signature synthetic bass sound pulsing in groups of four and the swooping portamento sine-wave lead. That woman was Delia Derbyshire of the BBC Radiophonic Workshop.
This video, courtesy of Movie Pilot and BBC America, traces the evolution of the theme from its first version -- mainly done using the pre-synthesizer tape-splicing techniques of musique concrete -- through the analog synth-drenched 1970s to the heavily orchestrated version of today's series.
