The nine Solfeggio frequencies

Solfeggio tones are used in spiritual listening and meditation. Think of the associations below as intentions for your practice, not promises about what a frequency will do.

You can choose a tone by the theme you want to explore, or simply by what you enjoy hearing. Our listening ideas below are optional meditation prompts: there is no single correct way to use them, and you do not need to feel anything special.

Only Hz Solfeggio 9: nine golden circles labelled 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz, in ascending order.

174 Hz

Grounding & comfort

In spiritual listening, 174 Hz is associated with grounding, comfort and a sense of safety.

Listening idea Make this a pause at the end of a busy day. Sit or lie comfortably and notice where your body meets the chair, bed or floor. Imagine roots reaching into the earth, and let the steady tone be a point to return to whenever your attention wanders.

285 Hz

Renewal & energy balance

285 Hz carries themes of renewal and replenishment, with an emphasis on restoring a sense of energetic balance.

Listening idea Use this session to mark a transition between one part of your day and the next. Ask yourself what you would like to make room for. Picture setting down yesterday's unfinished tasks, without needing to solve them now, and choose one small intention for the time ahead.

396 Hz

Letting go of fear & guilt

396 Hz is associated with releasing guilt, fear and limiting beliefs, and welcoming a lighter emotional perspective.

Listening idea Bring to mind an everyday worry or expectation you no longer want to carry. Silently name it, then imagine placing it beside you while you listen. You do not have to force a feeling of release; noticing what is present can be enough for this moment.

417 Hz

Change & new beginnings

417 Hz symbolises clearing old patterns and negative energy. Its central spiritual theme is openness to change.

Listening idea Choose a small change you want to welcome, whether that is a new habit, a fresh perspective or simply a different pace. Imagine stepping through an open doorway. At the end of the session, write down one manageable step that would help you move in that direction.

528 Hz

Love & transformation

Often called the love frequency, 528 Hz is associated with transformation, imagination and heartfelt intention.

Listening idea Let kindness be the focus of this meditation. Rest a hand over your heart if that feels comfortable, and offer yourself a simple phrase such as 'I can meet this moment with care.' Listen without expecting a special sensation, and return gently to the phrase when you wish.

639 Hz

Connection & harmonious relationships

639 Hz is associated with connection, understanding and communication, particularly in relationships with others.

Listening idea Think of someone you care about, or begin with yourself. Silently offer a wish for peace or understanding. If a conversation has been on your mind, reflect on what you would like to express and what you could listen to more closely, without trying to resolve everything during the session.

741 Hz

Clarity & self-expression

741 Hz is linked with clear thinking, creativity and self-expression, often as a theme for problem-solving.

Listening idea Keep a notebook nearby and choose one question to sit with. Rather than searching for an immediate answer, notice which thoughts keep returning. When the session ends, jot down a few words or ideas. Treat them as possibilities to explore, not instructions that you must follow.

852 Hz

Inner awareness & perspective

852 Hz is associated with inner awareness and shifting from negative thought patterns towards a more constructive outlook.

Listening idea Ask yourself what matters most right now, then leave some space around the question. Let thoughts come and go while the tone accompanies you. If you notice a harsh judgement, try restating it in kinder, more balanced language, without insisting that you have to feel positive.

963 Hz

Unity & higher consciousness

963 Hz carries spiritual associations with higher consciousness, intuition and connection beyond the everyday self.

Listening idea Picture the space around you extending beyond the room. You might reflect on your connection with nature, other people or something sacred to you. There is no particular experience to achieve; let the session be an opportunity for quiet attention, curiosity and a wider perspective.
