Who wrote the Doctor Who Soundtrack? It was composed by an Australian Composer - Ron Grainer but was actually created by Delia Derbyshire at the BBC Radiophonic Workshop in 1963. To create the sounds she'd spend countless hours cutting, splicing, speeding up and slowing down segments of analogue tape containing recordings of a single plucked string, white noise, and the simple harmonic waveforms of test-tone oscillators. Then the sounds were modified until every sound was the right pitch, and then re-recorded at different levels to create dynamics. Then the notes were trimmed to the right length - cutting and sticking the tape back together in the right order. Then mixing each tape on a separate tape machine
"Grainer was amazed at the resulting piece of music and when he heard it, famously asked, "Did I write that?" Derbyshire modestly replied, "Most of it." However the BBC, who wanted to keep members of the Workshop anonymous, prevented Grainer from getting Derbyshire a co-composer credit and a share of the royalties". Imagine doing all that work and not being credited?
