My invention relates to an improved method of and means for accurately combining sound with motion pictures. It has been found in practice difficult to synchronize sound and motion in pictures. The usual method has been to project the picture on a screen and produce the sound in the correct tempo, the synchronizer being the leader of an orchestra or director of any sound upon whose careful eye and ear the accuracy depends. My improved method and means tend to eliminate inaccuracy in scoring sound upon motion pictures.
