Is Music Worth Saving?
No great volume of evidence is required to answer this question. Music is a well-nigh universally beloved art. From the beginning of history, men have turned to musical expression to lighten the burdens of life, to make them happier. Aborigines, lowest in the scale of savagery, chant their song to tribal gods and play upon pipes and shark-skin drums. Musical development has kept pace with good taste and ethics throughout the ages, and has influenced the gentler nature of man more powerfully perhaps than any other factor. Has it remained for the Great Age of Science to snub the Art by setting up in its place a pale and feeble shadow of itself?
This system used an operator adjusted non-linkage form of primitive synchronization. The scenes to be shown were first filmed, and then the performers recorded their dialogue or songs on the Lioretograph (usually a Le Éclat concert cylinder format phonograph) trying to match tempo with the projected filmed performance. In showing the films, synchronization of sorts was achieved by adjusting the hand cranked film projector's speed to match the phonograph. the projectionist was equipped with a telephone through which he listened to the phonograph which was located in the orchestra pit.
