Sound -> Vibration -> Waves -> Cymatics

Sound -> Vibration -> Waves -> Cymatics [1]

Scope:

This video isn't really Science versus Music, but rather one of the places where Science and Art meet. In this case the science makes the music visible.
This kind of science is called Cymatics [3]

Good vibrations: the science of sound

We look around us—constantly. But how often do we listen around us? Sound is critically important to our bodies and brains, and to the wider natural world. In the womb, we hear before we see. Join John Schaefer, Jamshed Bharucha, Christopher Shera, the Danish sound artist Jacob Kirkegaard and multi-instrumentalists Polygraph Lounge for a fascinating journey through the nature of sound. How we perceive it, how it acts upon us and how it profoundly affects our well-being—including a demonstration of sounds produced by sources as varied as the human inner ear and the creation of the universe itself.

Sound resonance experiment

This experiment is the Chladni plate experiment. I used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker. First add sand to the plate then begin playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand "falls" into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.

The physics of sound creating form

Here you can see the power of sound creating form. (an earlier version of the experiment above)
A simple experiment demonstrating the visualisation of cymatics can be done by sprinkling sand on a metal plate and vibrating the plate, for example by drawing a violin bow along the edge, the sand will then form itself into standing wave patterns such as simple concentric circles. The higher the frequency, the more complex the shapes produced, with certain shapes having similarities to traditional mandala designs.

Some statements on sound and vibration

The Sufi Master Hazart Khan states "People say the soul on hearing the song of creation entered the body but, in reality the soul itself was the song".
Francis Crick, Co-Discoverer of DNA: "Consciousness is somehow a by-product of the simultaneous, high-frequency firing of neurons in different parts of the brain. It's the meshing of these frequencies that generates consciousness, just as tones from individual instruments produce the rich, complex, and seamless sounds of a symphony orchestra."
Beethoven "Music is the mediator between the life of senses and the life of spirit."
From the Bible: "In the beginning was the WORD (meaning Primary Harmony) and the WORD was with God and God SAID Let there be light." ..."And the WORD was made flesh and dwelt among us, full of grace and truth" John1:14.
Goethe: "Architecture is crystallized music."
Rudolph Steiner: "The Science of the future will be based on sympathetic vibrations."
Isaac Stern, renowned violinist: "Everything we do is connected to music. Civilization is based on a certain level of discipline and order, and this is the essence of the structure of music."
Leonard Bernstein "I believe that from the earth emerges a musical poetry which is by the nature of its source tonal. I believe that these sources cause to exist a phonology of music, which evolves from the universal known as the harmonic series. And that there is an equally universal musical syntax which can be codified and structured in terms of symmetry and repetition."
Paramahansa Yogananda, The Yoga of the Bhagavad Gita: "In the microcosmic universe of the body of man, the Aum vibrations works trough the vital activities in the astral spinal centers of life with their creative vibratory elements (tattvas) of earth, water, fire, air, and ether. Through these, mans body is created, enlivened, and sustained. These vibrations emit characteristic vibrations of Pranava as they operate. The devotee whose consciousness becomes attuned to these inner astral sounds finds himself gradually ascending to higher states of realization."
The Sufi Hazrat Kahn: "Music should be healing, music should uplift the soul, music should inspire; then there is no better way of getting closer to God, of rising higher towards the spirit, of attaining spiritual perfection, than music, if only it is rightly understood."

Sound & Water Experiment

The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you'd have to use a strobe light.

Sound & Flames

Sound waves are transmitted through a flammable gas creating alternating high and low pressure zones. This creates the flame pattern.
