The techniques initially used by the Radiophonic Workshop were closely related to those used in ''musique concrète''; new sounds for programmes were created by using recordings of everyday sounds such as voices, bells or gravel as raw material for "radiophonic" manipulations. In these manipulations, audio tape could be played back at different speeds (altering a sound's pitch), reversed, cut and joined, or processed using [[reverb effect|reverb]] or equalisation. The most famous of the Workshop's creations using 'radiophonic' techniques include the ''Doctor Who'' theme music, which [[Delia Derbyshire]] created using a plucked string, 12 oscillators and a lot of tape manipulation; and the sound of the TARDIS ([[Doctor (Doctor Who)|the Doctor's]] [[time travel|time machine]]) materialising and dematerialising, which was created by Brian Hodgson running his keys along the rusty bass strings of a broken piano, with the recording slowed down to make an even lower sound.<ref name="EMM81">{{cite magazine|title=Radiophonic Workshop: A Glimpse of Current Activities|url=https://www.muzines.co.uk/articles/radiophonic-workshop/2579|magazine=Electronics & Music Maker|via=Mu:zines |date=March 1981|access-date=18 January 2024}}</ref>

Much of the equipment used by the Workshop in the earlier years of its operation in the late 1950s was semi-professional and was passed down from other departments, though two giant professional tape-recorders made an early centrepiece. Reverberation was obtained using an [[echo chamber]], a basement room with bare painted walls empty except for loudspeakers and microphones. Due to the considerable technical challenges faced by the Workshop and BBC traditions, staff initially worked in pairs with one person assigned to the technical aspects of the work and the other to the artistic direction.
