The Solfeggio Frequencies are a set of nine tones believed to have healing properties and the ability to align the mind, body, and spirit. Rooted in sacred ancient traditions, these frequencies were rediscovered in the 1970s by Dr. Joseph Puleo, who identified them within the Bible’s Book of Numbers. They were originally used in Gregorian chants and are regarded as carrying profound spiritual and therapeutic significance.
The following is an overview of each of the nine Solfeggio Frequencies, including a brief summary of their benefits and historical associations.
You can listen to all of the frequencies via the play buttons for each, and can also listen to each within the Solfeggio Frequency Chart to compare different tones to see which resonant most with you.

174 Hz is widely known as a grounding and stabilizing tone, often used when the intention is to create a felt sense of safety in the body. Practitioners frequently associate it with easing physical discomfort, reducing emotional pressure, and helping the system settle out of high-alert states into a calmer baseline.
285 Hz is commonly associated with regeneration, restoration, and energetic repair. It is often used for intentions related to cellular renewal, tissue support, and recalibration after periods of fatigue, stress, or depletion.
396 Hz is known for work related to fear, guilt, and emotional heaviness, and is often used when the goal is liberation from limiting internal patterns. It is commonly described as a frequency that supports emotional release and a shift toward resilience, confidence, and grounded optimism.
417 Hz is strongly associated with transition, change, and forward movement. It is frequently used to clear the energetic residue of past experiences and support transformation when someone is moving from one life chapter, habit, or emotional state into another.
528 Hz is one of the most recognized Solfeggio tones and is widely known as the frequency of love, coherence, and transformation. It is commonly associated with heart-centered states, creativity, emotional renewal, and traditions that frame it as supportive of DNA-level harmonization.
639 Hz is known for relationship harmonization, communication, and reconnection. It is frequently used to support empathy, mutual understanding, and emotional alignment in partnerships, families, and group settings.
741 Hz is commonly associated with purification, clarity, and detoxification at both mental and energetic levels. It is often used to support cleaner thinking, intuitive discernment, and release of patterns that feel congestive or misaligned.
852 Hz is widely used for intuition, insight, and expanded spiritual awareness. It is associated with third-eye activation and is often chosen when the intention is to deepen perception and access higher-order clarity.
963 Hz is associated with divine connection, unity consciousness, and spiritual illumination. It is commonly regarded as a crown-centered tone that supports transcendence, deep stillness, and connection with the universal field.
The Solfeggio Frequencies are deeply rooted in spiritual practices and sound-healing traditions. By incorporating these tones into meditation, sound therapy, or daily life, individuals can support healing, spiritual growth, and emotional balance.

At Being Well, we utilize the 9 Solfeggio Frequencies through Frequency Entrainment within specific Energy tool designs. This practice commonly involves introducing specific frequencies within the tools during the post-production phase in a professional audio engineering studio using physical connections via frequency generators, or exposure using isolated high-quality audio.
Frequency Entrainment is a complex topic; however, in simple terms, it is the process of imparting the attributes of a specific frequency within copper’s crystalline lattice structure, therefore allowing it to serve as a carrier of the stable vibrational signature associated with the positive energetic qualities of the given frequencies.
This results in a highly distinct energetic profile whereby the emitted energetic field is tuned for focused use cases such as meditation, chakra alignment, energetic clearing, emotional balance work, and much more.
In addition to the 9 Solfeggio Frequencies, we also commonly use entrainment references including 432 Hz for natural resonance, 7.83 Hz Schumann Resonance baseline, and other related beneficial frequencies.
