A classic of Science fiction cinema Forbidden Planet's innovative electronic music score (credited as "electronic tonalities" ) was composed by Louis and Bebe Barron. The Barron's score is widely credited with being the first EVER completely electronic score!
Using ideas and procedures from the book, Cybernetics: Or, Control and Communication in the Animal and the Machine (1948) by Norbert Wiener, Louis Barron constructed his own electronic circuits that he used to generate the "bleeps, blurps, whirs, whines, throbs, hums, and screeches". After recording the basic sounds, the Barrons further manipulated them, adding effects, such as reverberation and delay, and reversing or changing the speeds of certain sounds. Since Louis and Bebe Barron did not belong to the Musicians Union, their work could not be considered for an Academy Award in either the "soundtrack" or the "sound effects" categories that year. What a bizarre injustice this is will become clear when you hear their wonderful "tonalities"......
