Sound film
The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was "The Jazz Singer", released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
Film score
Before the age of recorded sound in motion pictures, efforts were taken to provide suitable music for films, usually through the services of an in-house pianist or organist, and, in some cases, entire orchestras, typically given cue sheets as a guide. A pianist was present to perform at the Lumiere brothers' first film screening in 1895. In 1914, The Oz Film Manufacturing Company sent full-length scores by Louis F. Gottschalk for their films. Other examples of this include Victor Herbert's score in 1915 to "The Fall of a Nation" (a sequel to "The Birth of a Nation") and Camille Saint-Saëns' music for "The Assassination of the Duke of Guise" in 1908. It was preceded by Nathaniel D. Mann's score for "The Fairylogue and Radio-Plays" by four months, but that was a mixture of interrelated stage and film performance in the tradition of old magic lantern shows. Most accompaniments at this time, these examples notwithstanding, comprised pieces by famous composers, also including studies. These were often used to form catalogues of photoplay music, which had different subsections broken down by 'mood' and genre: dark, sad, suspense, action, chase, etc.
