Healing with Acoustic Resonance

Drumming is a profound way to promote healing. Through acoustic resonance, drumming helps restore the vibrational integrity of body, mind, and spirit. Acoustic resonance is the ability of a sound wave to impart its energy to a substance such as air, wood, metal, or the human body, making it vibrate in sympathy. For example, when you tap a tuning fork in proximity to another one of the same tone, both will vibrate. Acoustic resonance is an important consideration for instrument builders, as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute, and the shape of a drum membrane. A single-headed frame or hoop drum works best for acoustic resonance healing--the larger the drum, the greater the resonance.
 

The drum is a powerful tool for healing. As we play the drum, the drum then plays our bodies. The various frequencies of the drum interact with our own resonant frequencies, forming new harmonic alignments. Through the natural law of resonance, the sound waves produced by the drum impart their energy to the resonating systems of the body, mind and spirit, making them vibrate in sympathy. When we drum, our living flesh, brainwaves and spiritual energy centers entrain or synchronize to the sound waves and rhythms. This sympathetic resonance has the following key effects:
 

1. It produces deeper self-awareness by inducing synchronous brain activity. Research has demonstrated that the physical transmission of rhythmic energy to the brain synchronizes the two cerebral hemispheres. When the logical left hemisphere and the intuitive right hemisphere begin to pulsate in harmony, the inner guidance of intuitive knowing can then flow unimpeded into conscious awareness. The ability to access unconscious information through symbols and imagery facilitates psychological integration and a reintegration of self. Drumming also synchronizes the frontal and lower areas of the brain, integrating nonverbal information from lower brain structures into the frontal cortex, producing feelings of insight, understanding, integration, certainty, conviction, and truth, which surpass ordinary understandings and tend to persist long after the experience, often providing foundational insights for religious and cultural traditions.
 

2. It releases negative feelings, blockages, and emotional trauma. Drumming can help people express and address emotional issues. Unexpressed feelings and emotions can form energy blockages. The physical stimulation of drumming removes blockages and produces emotional release. Sound vibrations resonate through every cell in the body, stimulating the release of negative cellular memories.
 

3. It accesses the entire brain. The reason rhythm is such a powerful tool is that it permeates the entire brain. Vision for example is in one part of the brain, speech another, but acoustic resonance penetrates the whole brain. The sound of drumming generates dynamic neuronal connections in all parts of the brain even where there is significant damage or impairment such as in Attention Deficit Disorder (ADD). According to Michael Thaut, director of Colorado State University's Center for Biomedical Research in Music, "Rhythmic cues can help retrain the brain after a stroke or other neurological impairment, as with Parkinson’s patients...." The more connections that can be made within the brain, the more integrated our experiences become.
 

4. It induces natural altered states of consciousness. Rhythmic drumming induces altered states, which have a wide range of therapeutic applications. A landmark study by Barry Quinn, Ph.D. demonstrates that even a brief drumming session can double alpha brain wave activity, dramatically reducing stress. The brain changes from Beta waves (focused concentration and activity) to Alpha waves (calm and relaxed), producing feelings of euphoria and well-being. Alpha activity is associated with meditation, shamanic trance, and integrative modes of consciousness.
 

5. It helps us to experience being in resonance with the natural rhythms of life. Rhythm and resonance order the natural world. Dissonance and disharmony arise only when we limit our capacity to resonate totally and completely with the rhythms of life. The origin of the word rhythm is Greek meaning "to flow." We can learn to flow with the rhythms of life by simply learning to feel the beat, pulse, or groove while drumming. When drummers feel this rhythmic flow, especially at a slower, steady beat, they can shift into a state of deep relaxation and expanded awareness. It is a way of bringing the essential self into accord with the flow of a dynamic, interrelated universe, helping us feel connected rather than isolated and estranged.
