The Halloween Theme is the main theme music of the Halloween series.
The Theme is written in the rare 5/4 time signature. Director John Carpenter composed the simple, chilling music as it was the first thing his father had taught him how to play on a piano.
The original theme features a simple piano music.
The film's score was a variation of Carpenter compositions from Halloween, particularly the main theme's familiar piano melody played in a 5/4 time rhythm. The score was performed on a synthesizer organ rather than a piano. Overall the score is on a much grander and darker than the simple piano music of its predecessor. Many regard it as superior to the original due in no small part to its different instruments used to create a different mood. One reviewer for the BBC described the revised score as having "a more gothic feel." The reviewer asserted that it "doesn’t sound quite as good as the original piece", but "it still remains a classic piece of music." Carpenter performed the score with the assistance of Alan Howarth, who had previously been involved in Star Trek: The Motion Picture (1979) and would work again with Carpenter on projects such as Escape from New York (1981), The Thing (1982) and Christine (1983).
The Halloween 3 theme utilizes the basic theme of the original film along with some new synthesizer music.
Closer to the original theme than 2's theme, this one features a drum beat and synthesizer music along with piano.
Halloween 5's theme is played entirely on a synthesizer. The theme itself is in a higher key than the rest but the lower keys are played much lower than the other themes as well.
Halloween 5's theme is thought by some to be the best part of the film.
Halloween 6's theme was mostly disliked by audiences. The original music score is composed by long-time Halloween contributor Alan Howarth, his work in the series dating back to his collaboration with John Carpenter on Halloween II. However, Howarth's score was redone when the film went through reshoots. A soundtrack album was released by Varèse Sarabande, and is an unusual combination of the music featured in the original cut of the film, as well as that of the final theatrical cut. Basically the Halloween 6 theme features a tapping beat amongst a loud guitar rock version of the Halloween theme.
Halloween: H20's music was the most ambitious in the series aside from Part II. It featured an orchestra.
Closer to the original music once again because it was played on a piano but this remix featured the violins from the orchestra in the background, playing homage to the H20 music.
