Solfeggio Frequencies Chart: All 9 Tones, Benefits & How to Use Them
What Are the Solfeggio Frequencies? (Quick Answer)
The Solfeggio frequencies are a set of nine ancient healing tones ranging from 174 Hz to 963 Hz. Each frequency is associated with specific physical, emotional, and spiritual healing properties and corresponds to one of the body's main energy centers. Originally used by Gregorian monks in sacred chanting and largely lost for centuries, they were rediscovered in the 1990s and are now used worldwide in sound healing, meditation, and chakra balancing practices.
This post gives you the complete Solfeggio frequencies chart, the benefits of each tone, how to use them, and everything you need to know to start working with the full nine-frequency system.

The History of the Solfeggio Frequencies
The Solfeggio frequencies trace their origins to a medieval hymn to John the Baptist known as Ut queant laxis, in which each successive line of the chant was sung at a higher tone of the scale. The syllables Ut, Re, Mi, Fa, Sol, La, which are the direct ancestors of the modern Do Re Mi, each corresponded to a specific frequency. Gregorian monks used these tones in sacred meditation and ritual for centuries, and the tonal system was understood to carry specific healing and spiritual properties.
The original six-tone scale was gradually lost as Western musical tuning systems shifted, and the frequencies disappeared from mainstream use for several hundred years. They were rediscovered in the 1990s by Dr. Joseph Puleo, who identified them through a process of Pythagorean numerical reduction applied to ancient biblical texts. Dr. Leonard Horowitz later expanded on this research, identifying the extended nine-tone system and naming 528 Hz the Love Frequency, which brought widespread public attention to the entire scale.
Today the Solfeggio frequencies are used by sound healers, meditation practitioners, and millions of individuals worldwide who incorporate them into daily listening, sleep support, chakra balancing, and spiritual practice.
What Is the Science Behind the Solfeggio Frequencies?
The scientific study of Solfeggio frequencies is still developing, but the research that does exist is significant. The most studied frequency is 528 Hz, which has been the subject of multiple peer-reviewed studies with measurable results.
A 2018 study at Juntendo University found that just five minutes of 528 Hz music measurably reduced cortisol, the primary stress hormone, and nearly doubled oxytocin, the bonding and relaxation hormone. A separate study published in the Journal of Acupuncture and Meridian Studies documented a significant positive effect on the parasympathetic nervous system, the physiological state required for healing and genuine rest. Research published in the Journal of Advanced Research found that 528 Hz increased expression of genes associated with DNA repair. A University of Tehran study found it increased cell viability by approximately 20% and reduced reactive oxygen species, markers of cellular stress.
Beyond 528 Hz, the broader science of sound healing is well established. Neuroscience has confirmed that sound directly influences brain wave activity, autonomic nervous system regulation, heart rate, cortisol levels, and cellular function. Vibroacoustic therapy research has documented that sound vibration delivered to the body supports lymphatic flow, tissue healing, and pain reduction. These mechanisms apply across the Solfeggio system, not only to 528 Hz.
The honest scientific position is that Solfeggio frequencies have measurable physiological effects, that the research is promising but still developing, and that they work most powerfully as a complement to other wellness practices rather than as a standalone treatment for any specific condition.
The Solfeggio Frequencies and the Chakra System
One of the most useful aspects of the Solfeggio system is the way it maps onto the seven chakras, the body's main energy centers. Each frequency from 396 Hz upward corresponds to a specific chakra, while the two foundation tones of 174 Hz and 285 Hz work below the chakra system at the level of the physical body itself.
This mapping gives you a practical diagnostic tool: when you notice patterns in a specific area of your life, whether that is chronic fear, creative blocks, relationship difficulties, difficulty speaking your truth, mental fog, or spiritual disconnection, the corresponding Solfeggio frequency gives you a direct vibrational path to work on that area.
The Root Chakra and its frequency of 396 Hz address survival, safety, and the emotional patterns of fear and guilt. The Sacral Chakra and 417 Hz address creative flow, emotional fluidity, and the clearing of stuck patterns. The Solar Plexus and 528 Hz address personal power, self-love, and transformation. The Heart Chakra and 639 Hz address love, connection, and forgiveness. The Throat Chakra and 741 Hz address authentic expression, detoxification, and clarity. The Third Eye and 852 Hz address intuition, perception, and inner vision. The Crown Chakra and 963 Hz address divine connection and the direct experience of spiritual unity.

How to Use the Solfeggio Frequencies
Start with the complete playlist. If you are new to Solfeggio frequencies and are not sure where to begin, the most effective starting point is the full nine-frequency playlist, which sequences through all nine tones from the foundation to the crown. This creates a complete bottom-to-top healing session that addresses every dimension of the human system simultaneously.
Match the frequency to your intention. Once you are familiar with the system, you can use individual frequencies based on what you are working on. Anxiety and fear respond to 396 Hz. Stuck patterns and creative blocks respond to 417 Hz. Stress, self-doubt, and cellular health respond to 528 Hz. Relationship healing and opening the heart respond to 639 Hz. Authentic expression and physical detox respond to 741 Hz. Intuition and mental clarity respond to 852 Hz. Spiritual connection and deep peace respond to 963 Hz. Physical pain and tension respond to 174 Hz. Recovery from illness or injury responds to 285 Hz.
Listen with intention but without agenda. Before you begin, take a slow breath and set a simple intention for what you want to work on or open to. Then release the need to control or evaluate what happens. The frequencies work whether or not you have a perfect meditation experience. Distraction, falling asleep, or feeling nothing in particular during a session does not mean it is not working.
Use headphones when possible. Headphones allow the frequency to interact more fully with the body and the auditory system. They are not required, but they enhance the depth of the experience, particularly for the higher frequencies that work on more subtle dimensions.
Listen consistently. Single sessions produce real effects, but the cumulative benefit of daily listening over weeks is where the most meaningful and lasting changes occur. Even twenty to thirty minutes a day is enough. The body and energy system respond to consistent vibrational input over time in ways that a single session cannot produce.
Use it during sleep. Many people play Solfeggio frequencies softly through the night. Sleep is the body's primary healing and regeneration window, and sustained frequency exposure during sleep can produce noticeably different results than daytime listening alone. There are no documented adverse effects from overnight listening at comfortable volumes.
Which Solfeggio Frequency Should I Start With?
The answer depends on where you are and what you need most right now.
If you feel chronically anxious, unsafe, or financially stressed, begin with 396 Hz. If you feel stuck in a pattern you cannot break or creatively blocked, begin with 417 Hz. If you want stress relief, cellular healing, and the most research-backed frequency in the system, begin with 528 Hz. If you are working through relationship wounds or want to open more fully to love, begin with 639 Hz. If you feel unable to speak your truth or are supporting your body through detox or illness, begin with 741 Hz. If your mind will not quiet down and you have lost touch with your own inner knowing, begin with 852 Hz. If you feel spiritually disconnected or are deepening a meditation practice, begin with 963 Hz. If you are in physical pain or need deep grounding in your body, begin with 174 Hz. If you are recovering from illness, surgery, or injury, begin with 285 Hz.
When in doubt, the complete nine-frequency playlist is always the right choice.

Frequently Asked Questions
What are the 9 Solfeggio frequencies? The nine Solfeggio frequencies are 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, and 963 Hz. Each frequency is associated with specific healing properties and corresponds to a different dimension of the human system, from the physical body at the lower end of the scale to divine consciousness at the highest.
What are the Solfeggio frequencies benefits? The benefits vary by frequency. As a system, the Solfeggio frequencies are associated with pain relief, tissue healing, emotional release, stress reduction, cellular health, relationship healing, authentic self-expression, awakened intuition, and spiritual connection. The most researched benefits are 528 Hz's documented effects on cortisol reduction, oxytocin increase, and cellular health markers.
How to use Solfeggio frequencies? Listen to them as music through headphones or speakers, during meditation, as background listening, or during sleep. Set a simple intention before you begin, choose the frequency that corresponds to what you want to work on, and listen consistently over time for cumulative results. The full nine-frequency playlist covers all dimensions in a single session.
What is the most powerful Solfeggio frequency? 528 Hz is the most studied and most widely regarded as the most powerful because of its documented effects on cortisol, oxytocin, cellular health, and DNA repair gene expression. However, the most powerful frequency for any individual is the one that addresses what they most need. For deep spiritual experience, 963 Hz is unmatched. For emotional clearing, 396 Hz or 417 Hz may be more powerful in the moment.
What are the 12 Solfeggio frequencies? Some sources reference a 12-frequency version of the Solfeggio scale that extends the original nine tones with three additional frequencies: 1074 Hz, 1152 Hz, and 1174 Hz. These are less widely used and less studied than the nine primary tones. The core system used in most sound healing practice and in our music is the nine-frequency scale.
Are the Solfeggio frequencies the same as binaural beats? No. Solfeggio frequencies are specific pure healing tones that are listened to directly. Binaural beats are created by playing two slightly different frequencies simultaneously, one in each ear, causing the brain to perceive a third frequency equal to the difference between the two. Both are used in sound healing and meditation, and many Solfeggio frequency tracks incorporate binaural beats within the music, but they are different tools working through different mechanisms.
Do Solfeggio frequencies actually work? The research on 528 Hz specifically is compelling, with multiple peer-reviewed studies documenting measurable physiological effects. For the broader system, the evidence is growing but still developing. Centuries of consistent cross-cultural use, the growing body of scientific research, and the widespread reports of meaningful benefit from regular listeners all point toward genuine effects. They work best as a consistent practice and as a complement to other approaches, not as a one-time fix or replacement for medical care.
How long should you listen to Solfeggio frequencies? Studies on 528 Hz used sessions as short as five minutes and documented measurable results. For meditative or chakra-healing purposes, twenty to sixty minutes is ideal. Many people listen overnight with no adverse effects. Consistency over time matters more than the duration of any single session.
