Faders start at 10%. Turn Power ON to hear all tones. Adjust Reverb, choose a Mix, or set a Timer.

Explore nine commonly used Solfeggio frequencies individually or blend selected tones to create your own sound session.
The generator includes pure-tone, binaural-beat and isochronic modes, together with adjustable levels, gentle fades, timers and prepared sound combinations.
Solfeggio frequencies are commonly given emotional, spiritual and symbolic meanings within contemporary sound-healing practice. These associations are provided as a framework for meditation and personal exploration rather than as scientifically established effects.
Use stereo headphones for binaural beats. Pure tones and isochronic tones can be played through speakers or headphones. Begin at a low, comfortable volume and keep your first session short.
Please consider donating to the Bright Beings Academy, so we can keep producing sound generators for your continuing exploration into sound healing. No gesture is too small. We welcome your support and good intentions.
1. Set your session length (e.g., 10–60 minutes).
2. Pick a starting preset (one‑click mix) to match your intention (relax, clear, focus, sleep).
3. Press Start and adjust individual tone faders gently.
Nine Solfeggio faders: 174, 285, 396, 417, 528, 639, 741, 852, 963 Hz.
Master volume with conservative output to avoid spikes.
One‑click mixes (presets) for common intentions.
Timer: 10, 20, 30, 45, 60‑minute options.
Ramps: Smooth fade‑in/out to minimise clicks when starting/stopping.
Start/Stop controls.
Modes: Pure Tone - Binaural Beat (For Headphones) - Isochronic Tone (For Speakers)
1. Pick an intention: Relax, emotional release, heart opening, focus, sleep, or spiritual practice.
2. Select a preset that fits your goal. Presets load at modest levels to protect your ears.
3. Start the session. Allow the fade‑in to complete before you tweak.
4. Shape the mix with 1–3 tones. Keep each fader modest (10–30%). Less is often more.
5. Fine‑tune gradually: Make small changes and give yourself 15–30 seconds to feel the effect.
6. Set the timer and settle. The fade‑out prevents abrupt endings.
Tip: For sleep, keep it quiet and favour the lower tones. For daytime focus, begin low, breathe slowly, and increase gradually.
These descriptions reflect traditional and contemporary associations. Use what resonates. No medical claims are made.
174 Hz – Ease & Soothing

Supportive for emotional clearing and letting go. Pairs well with slow, belly breathing.
417 Hz – Fresh Start & Change
Associated with resetting and moving through stuckness. Nice in short, focused sets.

Linked to empathy and relationships. Gentle community or partner practices suit this tone.

Often used for mental clarity and honest communication. Good before writing or speaking.
852 Hz – Intuition & Insight
Associated with inner listening. Try with eyes closed and slow nasal breathing.

Focus Block (20–30 mins): 417 + 741 low. Add 528 softly at the end.
Evening Wind‑down (20–40 mins): 174 + 285. Keep 396 very low if emotions feel active.
Heart Practice (12–18 mins): 528 + 639 with slow 5–6 bpm breathing.
No sound? Check master volume, your device output, and press Start (some browsers block autoplay).
Clicks or jumps? The mixer uses soft ramps. Lower the master, change tones slowly, and avoid large jumps.
Too intense? Reduce overall level and limit the mix to one or two tones.
They are widely used in wellbeing and meditation. Many people find them helpful. Evidence is evolving; we make no medical claims.
Quiet is best. You should be able to speak over the sound without strain.
Start with one or two. Add a third only if it truly helps.
Yes—keep levels low. Prefer 174/285. Avoid bright upper tones late at night.
Both work. Choose whichever lets you listen comfortably at low volume.
Would you like more guidance on using Solfeggio tones within a personal sound practice?
The Solfeggio Tones for Healing course offers focused learning for exploring these frequencies with greater understanding, care and intention.
These sound generators are provided for education, meditation and personal sound exploration. They are not medical devices and are not intended to diagnose, treat, cure or prevent any physical or mental-health condition. They are not a substitute for professional medical advice, diagnosis or treatment.
Use the generators only in a safe setting. Do not listen while driving, cycling, operating machinery, crossing roads or doing anything else that requires your full attention.
Begin at a low, comfortable volume and keep your first session short. Listening safety is affected by both volume and duration, so take regular breaks and avoid raising the volume to overpower background noise.
Stop listening immediately if you experience ear pain or pressure, dizziness, nausea, headache, agitation, disorientation, changes in hearing or increased ringing in the ears. Seek appropriate medical or audiological advice if symptoms persist or return.
If you experience tinnitus, hyperacusis, hearing loss, migraines, epilepsy, seizures or sensitivity to rhythmic sound, approach these tools with additional care and seek professional guidance when uncertain. If you know that particular sounds, music or rhythms can trigger seizures, do not use rhythmic sound generators without advice from your clinician.
Where a generator offers binaural beats, stereo headphones are required to hear the intended effect. Pure tones, isochronic tones and amplitude-modulated sounds can generally be played through speakers or headphones.
Your response to sound is personal. Choose only tones and listening methods that feel comfortable, and stop whenever a practice does not feel right for you.
