What 1927 musical was the first “talkie”?

'The Jazz Singer' is a 1927 American musical/drama film directed by Alan Crosland. It was the first feature-length film to include a synchronized recorded music score accompanied by lip-synced singing. It also featured speech in a handful of isolated sequences.

Although it wasn't initially apparent, the film's release marked the end of the silent film era and marked the dawn of sound films. Of course, silent films were still released for a time after the film's debut, but retrospectively 'The Jazz Singer' is seen as the turning point in modern cinema.

'The Jazz Singer' was produced by influential studio Warner Bros. and their newfound Vitaphone sound-on-disc system. This groundbreaking technique involved playing back or recording sounds on a gramophone in sync with a motion picture. Consequently of its pioneering style and filming techniques, in 1996, the film was selected for preservation in the National Film Registry of “culturally, historically or aesthetically significant” motion pictures.
