Exploring Resonance

No comments

Recently, we learned how a Resonant Breathing exercise. But what exeactly is resonance anyway?

Remember everything is vibration and every vibration and therefore, everything, has a natural frequency, called its resonant frequency. This is known as the fundamental tone and free resonance.

The principle of resonance tells us that vibrations of one body can reach out and cause another body to vibrate, if they have the same frequency.

We have all heard of an opera singer who can shatter a glass with their voice. This means the singer’s voice matches the pitch of the glass, which sets it into vibration. When the singer raises her pitch to vibrate faster than that of the glass, the glass begins to vibrate too fast to remain solid and thus the glass is shattered.

A second concept to consider the concept of resonance, or the next evolution of resonance is a concept called sympathetic resonance.

Sympathetic resonance expands the principle of resonance beyond matched frequencies to those that are harmonic matches. The subject of harmonics is much too complicated for this post, but four our purposes here, it is enough to know that most significant harmonics result from doubling the fundamental tone.

This idea is best demonstrated on an open piano with the damper pedal depressed. In this mode, all strings are free to sound. Playing a C1 (or bass C) in this mode will cause all other C strings to vibrate. This is because each C note is related. C2 is created by doubling C1. When the other C strings vibrate, this is called sympathetic resonance.

The third and final concept of resonance is we want to understand is forced resonance.

To understand forced resonance we must first understand that some simple substances can only resonate at a fixed natural frequency (tuning forks for example) Other things are more elastic in nature and have the ability to resonate at a variety of different frequencies (such as air, water, wood, earth, and the human body). Complex, elastic bodies not only have the ability to react to multiple frequencies they can serve as conductors in some ways, able to transmit a frequency from one place to another.

Consider a lightning strike, this powerful energy rips through these elastic bodies seeking the fastest route possible looking for a way to continue its journey. The elasticity of these bodies allow the energy (Vibration) to pass right through and exit out the other side.

This concept provides the foundation of sound healing; frequencies that can shift and change when combined with the concept of sympathetic resonance, we now have a powerful view of vibrational medicine coming into view.

Higher frequencies are king in the world of forced resonance and we will soon explore the concept of entrainment which will enhance your understanding of The power of Sound.
