🎶 Introduction
Sound healing, often experienced as a sound bath, uses resonant vibrations; through Tibetan and crystal singing bowls, gongs, drums, bells, chimes, guitar, and Solfeggio frequencies to promote wellbeing. Clinical studies are validating its broad-reaching effects across physical, mental, emotional, and spiritual dimensions. As a sound healer myself, I feel strongly with the connection between the human experience, and the sounds that surround us on a daily basis. With intentional sound healing, one can immerse their healing experience to a higher level, through the awareness of vibrations, to the intentions of what needs to be healed. If you have access to a sound healer in your area, I highly suggest taking a self care day and booking with that sound healer. OR if you feel called to buy a singing bowl, and start your own personal journey, I encourage you to answer this call. It is our human right to play music, whether it be through a guitar, drums, or singing bowls. It is our right, and we must claim it, rightfully.

How It Works
Sound healing works through a blend of physiological, neurological, and energetic mechanisms. Here's how different aspects of sound influence our mind, body, and spirit:
Brainwave Entrainment
Repetitive tones from singing bowls, gongs, or Solfeggio frequencies can synchronize brainwaves to specific frequencies, such as alpha (relaxed focus) or theta (deep meditative) states. This process, known as brainwave entrainment, calms the nervous system and enhances emotional processing, clarity, and creativity.Research confirms that sound frequencies can help guide the brain into slower rhythms associated with healing and restoration.
Vagal Stimulation
Low-frequency sounds, like those from buffalo drums, gongs, or OM chanting, can stimulate the vagus nerve, which governs the parasympathetic nervous system (our "rest and digest" mode).This stimulation can lead to slower heart rate, deeper breathing, and reduced inflammation, allowing the body to return to a state of balance. Some researchers refer to this as acoustic vagal nerve activation through resonance.
Physiological Resonance
Every cell in the body vibrates. When exposed to healing sounds, especially those with low frequencies, these vibrations can penetrate the body’s tissues, potentially supporting improved circulation, reduced pain perception, muscle relaxation, and even accelerated tissue repair.This is the foundation of vibroacoustic therapy, where sound is used as a physical stimulus to entrain cellular and organ-level activity.
Energetic & Spiritual Alignment
From ancient temples to modern holistic practices, many believe that sound can clear blockages in the energetic body, especially within the chakra system.Crystal singing bowls, for instance, are often tuned to frequencies associated with specific energy centers (like the heart or third eye). These vibrations may help to realign the body’s energy field, enhance intuition, and promote a feeling of interconnectedness.Spiritual traditions and anecdotal reports commonly cite spontaneous emotional release, visions, or profound peace after sound healing, suggesting deep levels of energetic integration.

A Personal Note from the Journey
In my own practice, I’ve witnessed profound transformations through sound. One client who struggled with chronic anxiety shared that after just two sessions using the gong, buffalo drum and crystal bowls, she felt “as if her nervous system had exhaled for the first time in years.” Her sleep improved, her emotional regulation deepened, and she began incorporating sound into her weekly self-care rituals. These shifts weren’t just physical; they were soul-level.
Simple Ways to Get Started
Curious but not sure where to begin? Start with small steps:
Try a 3-minute humming meditation: Just hum gently while placing your hand on your chest. Feel the vibration.
Use a free Solfeggio frequency app or playlist: Search “528 Hz healing frequency” or “396 Hz release fear.”
Begin with a single bowl or chime: Even one simple note repeated with intention can shift your state.

🌍 Honoring the Origins
Sound healing is not a modern invention, it is a sacred practice rooted in ancestral wisdom across continents and cultures. Long before scientific studies confirmed its effects, sound was known intuitively by many peoples as a medium for healing, prayer, and transformation.
Tibetan Buddhist monks have worked with singing bowls, overtone chanting, and sacred mantras for centuries to cultivate inner stillness and raise the frequency of both individual and collective consciousness. These metal alloy bowls are traditionally handmade and infused with intention, used in spiritual ceremonies, meditation, and energy clearing rituals.
Indigenous cultures around the world: From the First Nations of North America to Aboriginal peoples of Australia, have long utilized drumming, rattles, chanting, and voice to connect with the land, the ancestors, and the unseen realms. The drumbeat is often considered the “heartbeat of Mother Earth,” a rhythmic portal to trance, emotional release, and deep grounding. These instruments are not just tools, they are alive with spirit and story.
Sufi mystics engage in zikr, a devotional practice involving repetition of the names of God, sung or chanted in group ceremonies. This rhythmic intonation is designed to dissolve the ego and awaken union with the Divine. The sound becomes both an offering and a path to ecstatic spiritual states.
Gregorian monks of Christian monastic traditions used vocal harmonics and modal chanting, known as Gregorian chant, not only as a form of worship but as a method for attuning the mind to sacred silence and prayerful resonance. Their chants filled cathedral halls with meditative tones that still move listeners today.
Hindu and Vedic traditions gave rise to the use of bija mantras and Sanskrit chants such as "Om"revered as the primordial sound of the universe. These syllables are encoded with vibrational intelligence, often used to activate chakras, invoke deities, or guide meditation.
As modern sound healing gains popularity in wellness spaces, it’s vital to remember that these practices are not trends, they are living traditions, often passed down through generations as acts of devotion, resistance, and cultural preservation.
May we approach these lineages with reverence, humility, and gratitude.May we learn not only the techniques---but the spirit with which they were originally offered.And as we create and share our own sound medicine, may we honor those who came before.
