using digital synthesizers – was made to sound more mysterious than previous renditions but was only used for this single season of the series. Glynn's theme reverts to the traditional key of E minor, even though it is slightly detuned in some episodes (perhaps as a result of a mistake in the dubbing stage). The bassline was performed on a Roland Juno-6 synthesiser, while the melody and filtered noise effects were performed on a Yamaha DX21 and Korg 770 respectively. The theme removes the bass slides which were featured in all previous official arrangements, and is instead merged into the main bassline. The Glynn arrangement was itself replaced by a new arrangement by Keff McCulloch for the Seventh Doctor's era beginning with season 24 (1987). McCulloch's arrangement was made using a Sequential Circuits Prophet-5 synthesiser, with the initial 'sting' replaced by a crashing explosive sound. Producer John Nathan-Turner stated that the new music, logo and title sequence were to signal a fresh start to the programme. This was the first version of the theme since the little-used 1973 Delaware version to incorporate the "middle eight" into the opening credits (as well as the closing, although the closing credits saw them extended slightly). McCulloch's theme is in the key of A minor. Delia Derbyshire was reportedly unimpressed with McCulloch's version. 1996 The 1996 Doctor Who television movie used a fully orchestrated version, arranged by John Debney. This contained a new introduction, being a quieter piece of music over which part of the Eighth Doctor's (Paul McGann) opening narration was read, leading into a crescendo into the "middle eight", a departure from previous versions of the theme. Debney's version of the theme begins in A minor, but after the middle eight the main melody is transposed back to E minor, as in the original score. Less evident in this version of the score is the rhythmic bassline that opens and underscores all previous (and later) televised versions of the theme; a bassline is present, but it does not rise and fall in the same way. Debney is the only composer that receives screen credit during the movie, with the by-then-deceased Grainer not being credited on screen for composing the theme. Debney at one point was nearly asked to compose a new theme due to licensing issues regarding the Grainer composition. 2000s When Big Finish Productions began to produce Eighth Doctor audio plays
