These are examples that illustrate how flames at Stonehenge may have moved in time to the sound and music.
This first example above shows a simple drum beat being used to make a flame move in time to music. Now imagine Stonehenge at night, lit only by bare flames, and the effect of the flickering of all these flames moving in time to percussion rhythms and resonances in the space.
This second example is a 47Hz pitch, just like the strongest resonance we found at Stonehenge. When it is loud the flame gets fatter, it gets thinner when it is silent. The flame can be controlled and moved by pitch as well as by rhythms.
In the third example pitch and rhythm are put together. The 47hz bass tone has its volume modulated at a rhythmic frequency, and this is the kind of result we can expect. Dancing flames!
