Complete Record: Excerpts from well-known musical selections, Greensleeves, Clair de Lune and Afternoon of a Faun are used in this film to illustrate principles of sound. A split screen shows the source of sound on the upper half and an oscilloscope picture of the sound on the bottom. At the same time, we hear the sound produced by the instrument. The oscilloscope shows the differences between low and high pitch; loud and soft sounds; and noise and musical sounds. The motion picture techniques of animation, synchronous sound, multiple exposures and double printing are used in this film. Produced by Academy Films. Explores the basic principles of sound production, using three types of musical instruments: harp, flute, and xylophone. Uses the techniques of animation, synchronous sound, oscilloscope patterns, split screen, multiple exposures, and double printing to illustrate and explain the principles of musical tones. Includes excerpts from the musical selections, Greensleeves, Clair de lune, and Afternoon of a faun to illustrate the principles of sound.
