Monochord

The monochord is an ancient scientific and musical instrument, invented in Greece in c. 500 BC, used for the investigation and demonstration of musical phenomena.

This multi-stringed instrument is simple yet produces a beautiful Sound, an echo of the Cosmos. The vibration of all the strings at the same place simultaneously, has the effect of amplifying the harmonics pure overtones that usually remain undetected by the ear become clearly audible. In sound therapy it is used for its powerful soothing and calming effects.

Harmonics, otherwise known as Overtones, were discovered, at least in the Western civilization by, by the philosopher, musician and mathematician Pythagoras. Pythagoras discovered the law of the octave, a vitally important law for music but also for science in general. The monochord was also used as long ago as Ancient Egypt for discovering and calculating the harmonics and therefore the most harmonious, proportions for their sacred temples and pyramids.

Pythagoras and his followers believed that the whole universe could be understood in terms of musical harmonies G  and simple mathematical ratios. Until at least the 17th century astronomers such as Johannes Kepler XR  (1571-1630) believed that the planets moved in such a way as to produce a kind of cosmic harmony.
