Chakra Frequencies: The Seven Centres and the Tones Paired With Them

Picture seven points of light stacked along the spine, from the place where you sit to the crown of your head. Each one turns slowly, each one has its own colour and its own quality, and each one, in the oldest descriptions, has its own sound.

That last detail is easy to miss, and it is the reason the chakras belong on a site about listening. Long before anyone paired them with frequencies in hertz, the chakras were already described in syllables and letters, as if the body were an instrument waiting to be sounded. This entry follows that thread: where the chakras come from, how tones came to be matched with them, and how you might listen your way from root to crown.

What are chakra frequencies?

Chakra frequencies are tones paired with each of the seven chakras, so that a single sustained sound can be used to focus attention on one centre at a time. The most widely used set comes from the Solfeggio frequencies and climbs with the body: 396 Hz at the root, 417 Hz at the sacral centre, 528 Hz at the solar plexus, 639 Hz at the heart, 741 Hz at the throat, 852 Hz at the third eye and 963 Hz at the crown.

Chakra	Sanskrit name	Where it sits	Element	Seed sound	Frequency
Root	Muladhara	Base of the spine	Earth	LAM	396 Hz
Sacral	Svadhisthana	Below the navel	Water	VAM	417 Hz
Solar Plexus	Manipura	Above the navel	Fire	RAM	528 Hz
Heart	Anahata	Centre of the chest	Air	YAM	639 Hz
Throat	Vishuddha	Throat	Ether	HAM	741 Hz
Third Eye	Ajna	Between the eyebrows	Light	OM	852 Hz
Crown	Sahasrara	Top of the head	Thought	Silence	963 Hz

This is one map among several, and a young one. The chakras themselves are far older, and the story of how the two met is worth telling.

Where the chakras come from

Chakra is the Sanskrit word for "wheel". The idea of wheels or lotuses of energy along the body grew up in the tantric traditions of medieval India, and it did not arrive as a single fixed system. Different texts and lineages counted different centres, sometimes four, sometimes six, sometimes many more, and described them in different ways.

The version most of the world knows today comes largely from one text: the Ṣaṭ-cakra-nirūpaṇa, "the description of the six centres", written by the Bengali teacher Pūrṇānanda in 1577. It describes six lotuses rising along the central channel of the body, with a seventh, the thousand-petalled lotus, blooming at the crown above them all. In 1919 the English scholar John Woodroffe, writing as Arthur Avalon, translated it in The Serpent Power. That book carried the seven centres into the English-speaking world, where yoga teachers, theosophists and, later, a whole modern culture of meditation took them up.

Sound runs through that text from the start. Each lotus has a set number of petals: four at the root, then six, ten, twelve, sixteen, and two at the brow. Together that makes fifty, and each petal carries one letter of the Sanskrit alphabet, all fifty of them. The body, in this picture, holds the whole alphabet of sound. At the centre of each lotus sits a bija, or seed syllable: LAM, VAM, RAM, YAM, HAM for the five elements, and OM at the brow. The crown is left beyond syllables, as though what lives there can only be approached in silence.

The rainbow came later. In the old texts each lotus has its own colours, often quite unlike the ones we associate with it now. During the twentieth century, Western teachers laid the seven colours of the rainbow over the seven centres, red at the root to violet at the crown, and that simple, luminous scheme is the one you will find on most chakra charts today. It is a good example of how the tradition lives: every generation that works with the chakras adds something to them.

How frequencies joined the chakras

The frequency layer is the newest of all. The Solfeggio frequencies were described in the 1970s by the physician Joseph Puleo, who drew them from the medieval hymn to St John the Baptist and from numerical patterns in scripture. In the 1990s the writer Leonard Horowitz popularised them, and the set grew from six tones to nine, running from 174 Hz to 963 Hz. The 528 Hz entry tells that story in more detail.

As sound healing grew over the following decades, practitioners began matching those tones to the chakras. Seven of the nine fitted the seven centres, and the map settled into the order in the table above. The two lowest tones, 174 Hz and 285 Hz, sit outside it; many practitioners use them as a foundation, beneath the root or at the start of a session.

There is a quiet logic to the map. It climbs in pitch as it climbs the body: lower tones at the base, brighter ones towards the crown. Singers know a version of the same feeling. Low notes seem to resonate in the chest, which is why they speak of a "chest voice", and high ones seem to ring in the head. A map that rises from 396 Hz to 963 Hz follows the way sound already seems to move through us.

Other maps

Chakra and frequency pairings are a living, modern tradition, and not every teacher uses the Solfeggio map. A few others are common:

• The musical scale. Many crystal singing bowl and tuning fork sets are tuned to the notes C, D, E, F, G, A and B, one for each centre from root to crown. It is the same rising logic, expressed as a scale.
• Planetary tunings. In The Cosmic Octave, the Swiss mathematician and musicologist Hans Cousto derived tones from the orbits of the Earth, Moon and planets. Tuning forks based on his work, such as 136.10 Hz from the Earth's year, are widely used in chakra practice.
• Single tones at the heart. Many people work with 528 Hz, the Love Frequency, at the heart rather than the solar plexus, and 432 Hz is often chosen as a heart-centred tone.

Many people try a few maps and simply keep working with the one that resonates.

Root to crown: the seven tones

Root chakra: 396 Hz

The root is about weight and safety, the feeling of being held by the ground. Its tone, 396 Hz, is the first of the original six Solfeggio frequencies and carries the association of releasing fear. It is the lowest of the seven and the natural place to begin.

Sacral chakra: 417 Hz

The sacral centre, just below the navel, is the chakra of water: feeling, pleasure and creative flow. 417 Hz is associated with change and with clearing what has stalled, a fitting tone for a centre whose whole nature is movement.

Solar plexus chakra: 528 Hz

The solar plexus is the inner fire: will, confidence, the power to transform. Its tone, 528 Hz, is the famous Miracle Tone, named for the syllable mi and the Latin mira gestorum, "miracle of deeds". Here it takes the role of transformation.

Heart chakra: 639 Hz

The heart sits in the middle of the seven, the meeting place of the three centres below and the three above. 639 Hz is associated with relationship, harmony and understanding between people. Its Sanskrit name, Anahata, means "unstruck", after the sound yogis describe hearing inwardly in deep stillness.

Throat chakra: 741 Hz

The throat is where breath becomes voice, the centre of expression and truth. 741 Hz is a clear, bright tone connected with expression and clearing. It is also the easiest centre to work with using your own voice: hum along, and you can feel it.

Third eye chakra: 852 Hz

The third eye, between the eyebrows, is the seat of intuition and inner seeing, and its seed sound is OM. 852 Hz is high and shimmering, associated with insight and returning to spiritual order. Play it softly, so it seems to come from inside rather than from the room.

Crown chakra: 963 Hz

The crown, the thousand-petalled lotus, is unity and awareness, the place where the whole system opens out. 963 Hz is the highest tone of the set and is often used to close a session. When it stops, stay with the silence for a moment; in the old texts, that silence is the crown's own sound.

Listening through the chakras

One of the simplest practices is a slow journey up the body, one tone at a time:

1. Sit comfortably, or lie down, and let the breath settle.
2. Begin with the root tone. Play it quietly, quieter than feels natural, and rest your attention at the base of the spine.
3. After a minute or two, move to the next centre and its tone. Take your attention with you.
4. If it feels right, hum or softly chant each centre's seed syllable along with the tone: LAM, VAM, RAM, YAM, HAM, OM.
5. After the crown, stop the sound and sit in the quiet for as long as you like.

There is no right amount of time to spend at each centre, and no particular feeling you are supposed to find. Some people linger where they feel most drawn; others move evenly from one to the next. The chakra map has all seven tones ready to play in order, and each chakra's own page includes the other pairings, so you can compare maps by ear.

Listen for yourself

The chakras have been described in lotuses and letters, in syllables and colours, and now in hertz. Each generation has found its own way of sounding the same seven centres. The most interesting part is not deciding which description is correct but listening to them, and noticing where in your body each one seems to land.

Begin at the root, or wherever you are drawn, and see what you find.
