BBC Radiophonic Workshop, 60s Electronica.The following text comes from
an amazing site about the history of the Doctor Who theme tune.
Doctor Who - The Original ThemeDelia Derbyshire, with assistant Dick Mills, created the original version of the theme in August 1963 using techniques, described here, that applied for years, whether the sound sources were electronic or concrete.

In 1963, when the job of producing the Doctor Who theme landed at Delia's feet, there were no synthesisers. The sound for electronic music came either from pure electronic sources, or from recordings of actual live sounds - the precursor of what we now term "sampling". But sampling now is easy: capture a sound, assign it to a range of notes on a keyboard, and play. But musique concrete was not so easy forty years ago.

There being no "synthesisers", the Workshop needed a source of electronic sound. They found this in a bank of twelve high-quality test tone generators, the usual function of which was to output various tones (square waves, sine waves) for passing through electronic circuits for testing gain, distortion and so on. They also had a couple of high-quality equalisers (again, test equipment - equalisers, or "tone controls", were not that easy to come by at the time) and a few other gadgets including a "wobbulator" (a low frequency oscillator) and a white noise generator.
Each sound in the Doctor Who theme was individually created using these instruments, and recorded to magnetic tape. By "each individual sound" I mean just that - each note was individually hand-crafted. The swooping sounds were created by manually adjusting the pitch of the oscillator to a carefully-timed pattern. The rhythmic hissing sounds were created by filtering white noise to "colour" it, as were the "bubbles" and "clouds". Examination of the original makeup tapes suggests that one of the two bass lines alone is a "concrete" sound, a plucked string sample.

Once each sound had been created, it was modified. Some sounds were created at all the required pitches direct from the oscillators, others had to be repitched later. This was done by taking the piece of tape with the sound on and looping it. The loop was placed on a tape machine and its playback speed varied until the pitch was correct, then the sound was rerecorded onto another machine. This process continued until every sound was available at all the required pitches. To create dynamics, the notes were rerecorded at slightly different levels.
Now the fun really started. They had all the sounds, all the notes, and now had to create the music. So each individual note was trimmed to length by cutting the tape, and stuck together in the right order. This was done for each "line" in the music - the main plucked bass, the bass slides (an organ-like tone emphasising the grace notes), the hisses, the swoops, the melody, a second melody line (a high organ-like tone used for emphasis), and the bubbles and clouds. This done, they ended up with a number of lengths of cut tape with the individual parts on. Most of these individual bits of tape, complete with edits every inch, still survive.

This done, the music had to be "mixed". There were no multitrack tape machines, so rudimentary multitrack techniques were invented: each length of tape was placed on a separate tape machine and all the machines were started simultaneously and the outputs mixed together. If the machines didn't stay in sync, they started again, maybe cutting tapes slightly here and there to help. In fact, a number of "submixes" were made to ease the process - a combined bass track, combined melody track, bubble track, and hisses. Eventually, the piece was finished.
The result is an astonishing piece of work with a magically organic quality to it that belies the many hours of patient work it took to create. As I said at the start, it is a "pure" electronic work - there is no element of "performance" at all, yet it still sounds alive. Even more extraordinary is that you can listen to the Doctor Who theme now, nearly 40 years later, and still not work out exactly how it was done. It must be one of the most timeless recordings ever - still fresh and modern when later versions sound dated and stale.
Delia Derbyshire recalls that Ron Grainer was delighted with the result and, realising that the music worked perfectly well as it stood, abandoned his original plan of overdubbing a small instrumental ensemble (as in Giants of Steam). Recognising Delia's immense contribution, he also suggested splitting his performance royalty income with her, but BBC bureaucracy meant that this was not possible.
