What are Solfeggio frequencies
The term refers to a set of nine tones — 174, 285, 396, 417, 528, 639, 741, 852, and 963 Hz — widely used in sound healing, meditation, and relaxation practices. Each tone is associated with a specific intention: from releasing tension and emotional heaviness to encouraging focus, creativity, and a sense of connection.

Important distinction: solfège is the medieval sight-singing method with syllables do re mi fa sol la ti. It teaches relative pitch and does not assign specific Hertz values. Solfeggio frequencies are a separate, modern concept.

How to use them
There is no single correct way to listen. Most people treat them as background sound for an activity that benefits from calm focus:

Meditation and breathwork. Pick one frequency, set a comfortable volume, and sit with it for 10–30 minutes. Lower tones (174–396 Hz) tend to feel grounding; higher tones (741–963 Hz) feel more expansive.

Yoga and stretching. A single tone or a slow sequence (e.g. 396 → 528 → 741 Hz) can serve as a simple sonic backdrop without the distraction of lyrics or complex music.

Sleep and wind-down. Play a lower frequency at very low volume as you settle into bed. 174 Hz and 285 Hz are common choices for this.

Focused work or study. Some listeners find that a mid-range tone like 528 Hz or 639 Hz helps maintain concentration without being intrusive.

Start with 10–15 minutes per session. Use speakers or headphones at a volume that feels easy — softer usually works better than louder.
