Adding Sounds to FilmBefore The Jazz Singer, there were silent films. Yet despite their name, these films were not silent for they were accompanied by music. Often, these films were accompanied by a live orchestra in the theater and from as early as 1900, films were often synchronized with musical scores that were played on amplified record players.
The technology advanced in the 1920s, when Bell Laboratories developed a way to allow an audio track to be placed on the film itself. This technology, called Vitaphone, was first used as a musical track in a film titled Don Juan in 1926. Although Don Juan had music and sound effects, there were no spoken words in the film.
Actors Talking on FilmWhen Sam Warner of the Warner Brothers planned The Jazz Singer, he anticipated that the film would use silent periods to tell the story and the Vitaphone technology would be used for the singing of music, just as the new technology had been used in Don Juan. However, during the filming of The Jazz Singer, superstar of the time Al Jolson ad-libbed dialogue in two different scenes and Warner liked the end result.
Thus, when The Jazz Singer was released on October 6, 1927 it became the first feature-length film (89 minutes long) to include dialogue on the filmstrip itself. The Jazz Singer made way for the future of "talkies," which is what movies with audio soundtracks were called.
