<P> The "Theme from Star Trek" (originally scored under the title "Where No Man Has Gone Before") is an instrumental musical piece composed by Alexander Courage for Star Trek, the science fiction television series created by Gene Roddenberry and originally aired between September 8, 1966, and June 3, 1969 . </P> <P> The music was played over both the opening and closing credits of the original series . The opening credits begin with the now - famous "where no man has gone before" monologue recited by series star William Shatner, accompanied by an opening fanfare . The main theme begins, punctuated at several points by the Enterprise flying toward and past the camera with a "whoosh" sound for dramatic effect, created vocally by Courage himself . A slightly longer version of the theme, minus the fanfare, was played over the closing credits, which were overlaid on a series of stills from various episodes . </P>
