While the exact date of origin for Deep Note is unclear, detailed analysis by experts shows that it was likely commissioned around the late fifteenth century for His Royal Highness Theodore Hector the Tenth, popularly referred to as “THX” by historians. There are many legends surrounding its origin; the most popular says that King Theodore ordered that a sound be created that would ensure the audience was listening whenever a proclamation was made, and that if it was not finished within a week the composer would be sentenced to execution. (There has been much debate on the truth of this in recent years, although the majority find it at least somewhat amusing.) Recent evidence has shown at least one part of the legend to be true, however – the symphony was composed in only four days, an almost stupendous feat considering the sheer number of complex calculations involved in its creation [see “The Symphony,” below, for more information].
Deep Note was written to be played on a highly unusual and extremely rare instrument known colloquially as the “big-ass supercomputer,” and the musical score is written not in notes, but in a series of numbers which appear to represent some way of playing the instrument – a very unusual method. Because no known complete models of the big-ass supercomputer exist, it is still unknown how the instrument would be played, but parts of the instrument have been recently discovered, evidence which may eventually solve the mystery of the instrument. However it was played, however, historical evidence in the form of personal journals, official records, and other sources have indicated that the noise was “deafening,” and that those who played the instrument frequently went insane after only a few months.
Thousands of complex mathematical computations were used to create the work, and Moorer von Beethoven's own calculations are on display in the Smithsonian Institute show that the complexity of the calculations varies from basic arithmetic to multi-page calculus. Scratched-out sections and notes in the margins indicate that a great deal of the work used arbitrarily-chosen random numbers in the calculations, and mathematicians have determined that changing even a single digit could cause the entire symphony to be significantly altered.
One final aspect which makes the monumental work unusual is that it is one of the only symphonies in the entire world under thirty seconds long.
After extensive research and exhaustive guesswork, experts have created what is believed to be an accurate approximation of the symphony. Previous attempts have typically resulted in failure, and have caused some to question the methods used to reproduce the sound.
