Description: BBC Maida Vale contains four sound studios for music and drama. The studio was home to John Peel's Peel Sessions, a regular slot in which a current popular band would play a set exclusively for the show. It was also home to the BBC Radiophonic Workshop, created in 1958 to produce sound effects and new music for radio. 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 (the Doctor's 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. The Workshop was closed in March 1998.
