''Blake's 7''{{'}}s [[theme music]] was written by Australian composer [[Dudley Simpson]], who had composed music for ''Doctor Who'' for more than ten years. The same recording of Simpson's theme was used for the beginning titles of all four series of the programme.<ref name="Simpson">{{Cite web |url = http://www.dudleysimpson.com/discography.htm| title = Dudley Simpson Discography |archive-url = https://web.archive.org/web/20080229154350/http://www.dudleysimpson.com/discography.htm |archive-date=29 February 2008 | author = Chris Brimelow}}</ref> For the fourth series, a new recording was made for the closing credits that used an easy listening-style arrangement.<ref>Details largely taken from documentary included Blake's 7 series 4 DVD</ref> Simpson also provided the incidental music for all of the episodes except for the Series One episode "Duel" and the Series Two episode "Gambit". "Duel" was directed by [[Douglas Camfield]], who had a grudge against Simpson and refused to work with him, and so the episode contained library music.<ref>{{Cite web |title=Doctor Who Magazine issue 259, 17 December 1997 in Dr. Who/Douglas Camfield |url=http://experts.about.com/q/Dr-1102/Douglas-Camfield.htm |work=All Experts |date=12 July 2005 |access-date=17 January 2012 |archive-url=https://web.archive.org/web/20120330120515/http://en.allexperts.com/q/Dr-1102/Douglas-Camfield.htm |archive-date=30 March 2012 |url-status=dead}}</ref> [[Elizabeth Parker (composer)|Elizabeth Parker]] provided the music and sound effects for "Gambit". ''Blake's 7'' made considerable use of audio effects that are described in the credits as "special sound". Many electronically generated sound effects were used, ranging from foley-style effects for props including handguns, teleport sounds, spacecraft engines, flight console buttons and background atmospheres. The special sounds for ''Blake's 7'' were provided by the [[BBC Radiophonic Workshop]] composers [[Richard Yeoman-Clark]] and Elizabeth Parker.
