The opening title sequence theme, "The Mysterons", was rendered electronically and accompanied by a staccato drum beat to introduce the lead character of Captain Scarlet.[1] This seven-note beat was also used to link scenes within episodes,[1] and to cut to advertisement breaks,[52] for which it was accompanied by a zooming image of the Spectrum logo as designed by Tony Dunsterville of the art department.[52] On the subject of the beat, Anderson recalls, "When I went to the recording session, I heard the drum beat he had come up with and I thought, 'Christ, is this all he could produce?' Looking back on it, however, I can see that what he came up with worked very well."[52]
