Cymatics Experiment in the Great Pyramid

Few who have experienced the acoustics of the Great Pyramid's King's Chamber have not walked away with a feeling of awe, in some cases coupled with an impression that the chamber was designed to be reverberative. For a relatively small chamber the reverberation is indeed extraordinary; one can literally hear one's own breathing (when the fluorescent lighting is turned off!) and this experience often accompanies feelings of cathedral-like reverence. This notion of design implies a prior knowledge of acoustics and materials science. The high levels of reverberation in the chamber are actually a function of the flat granite surfaces, their parallel arrangement and the chamber's dimensions. Let us discuss the likelihood of acoustics design.

The earliest evidence of granite working in ancient Egypt dates to 3,900 BC at Nekhen, 1400
years before the Great Pyramid was built (around 2,500 B.C.) a long period in
which an acoustics science could have been acquired by the ancient Egyptian
engineers. However, an obvious question to ask is what would have driven their
need to control the acoustics environment? The answer, almost certainly,
relates to their desire to communicate with the spirit world during their
sacred ceremonies. The following quotation from Demetrius, circa 200 B.C., from "Aristotle, Poetics" suggests that purity of sound was important in his era: "In Egypt, when priests sing hymns to the gods, they sing the seven vowels in due succession and the sound of these vowels has such euphony that men listen to it instead of the flute and the lyre." Such ''euphony'' would, no doubt, have been enhanced by singing in reverberative chambers, just as reverberation plays an important function in churches today, to enhance one's sense of connection with spirit and to optimize the choir and organ performance. Although the date of this quotation is much later than the pyramid age it should be remembered that vowels were considered sacred throughout ancient Egyptian history and that Late Period customs invariably had their roots in early or even pre-dynastic times. It seems reasonable to suggest, therefore, that the ancient Egyptians of the 4th dynasty, when the Great Pyramid was built, used vowel sound chant as part of their ritual. However, even if their chant was not specifically vowel sound oriented, studies of ancient Egyptian cult texts of a religious character, by Waltraud Gugliemi, have revealed that, in many cases, they were intended to be sung rather than spoken. (The journal of: 'Ancient Egyptian Literature') Singing in enclosed spaces is always enhanced by reverberation. Dr. Lise Manniche, in her book ''Music & Musicians in Ancient Egypt'' provides confirmation of singing in relation to pyramids with the following quotation from Nikaure of the 5th dynasty. 'Instructor of the singers of the Pyramid of King Userkaf' This title, given to Nikaure, seems to indicate that a group of singers were retained specifically to maintain song or chant-based rituals at the pyramid of Userkaf, although whether the singers performed inside or outside the pyramid cannot be determined. Although I did
not carry out a Critical Distance Test in the King's Chamber (the distance
from a given sound source at which the level of direct energy, reaching one's
ears, equals the level of reflected energy) those readers who have visited the
Great Pyramid will know that even when two people are as close as one metre
apart, speech intelligibility is extremely poor in the King's Chamber.
However, this effect works very much in favor of chanting or singing, where
continuity not intelligibility,
is the prime concern. This is particularly relevant where extended vowel
sounds are employed, for example, in Gregorian Chant. Now consider the following extract from the ancient Egyptian Book of the Dead, translated by R.O. Faulkner in his book entitled ''The Book of the Dead.''
''The Mighty One appears,
the horizon shines. Atum appears on the smell of his censing, the Sunshine-
god has risen in the sky, the Mansion of the pyramidion is in joy and all its
inmates are assembled, a voice calls out within the shrine, shouting
reverberates around the Netherworld.'' One could interpret this spell as being suggestive of a ritual performed within a pyramid in which vocally generated sound played an important part, though further research is needed in which a corpus of ancient Egyptian texts is examined and interpretation of the transliterations is made.
R.A. Schwaller de Lubicz in his book, 'Sacred Science' also believed that the ancient Egyptians used sounds, as distinct from words, in their rituals. In the last sentence of the following passage he quotes from Corpus Hermeticum:
''Sacred or
magical language is not to be understood as a succession of terms ''The Pharaonic texts are rich in examples of litanies playing a magical role through the repetition of sounds...and through word play. The hieroglyphic writings allow us to confirm this although their transcription into our language is impossible since the pronunciation of this language is unknown...In a letter from Asklepios to King Amman[he says]: ''As for us, we do not use simple words but soundsall filled with power.'' (Emboldened words represent the Corpus Hermeticum reference) The acoustics study of the Great Pyramid was undertaken in order to investigate my hypothesis that (a) the King's Chamber was designed to be highly reverberative and (b) the chamber and its sarcophagus are acoustically coupled, that is, the energy of any sound made in the chamber is largely transferred into the sarcophagus. Such coupling was, I postulate, designed to support a rebirthing ritual enacted prior to the pharaoh's death or perhaps after his death.The King's Chamber sarcophagus is highly resonant, partly due to its high quartz content, hence the Egyptian architect"s choice of raw material since limestone and alabaster lack the resonant properties enjoyed by granite. I am of the opinion that vowel sound chant in the acoustically enhanced King"s Chamber was intended to have an energizing effect on the sarcophagus during sacred rituals. A clue as to what such rituals may have involved is given by Professor I.E.S. Edwards in his book 'The Pyramids of Egypt.' |

'According to one of the most popular myths . . . the sun-god Re entered the
mouth of the sky goddess Nut every evening, passed through her body and was
reborn at dawn. When he died, the King was assimilated to Re and was thought
to undergo the same nightly process of gestation and rebirth as the sun god.
