Seven tones commonly used in modern chakra meditation, with the mantras and research behind the chart.
Research has not established a measurable “natural frequency” for each chakra. The numbers below describe a modern sound-meditation convention; the themes offer a focus for contemplation.
A comparison for study
The Solfeggio assignments and the seed mantras come from separate systems. A mantra does not have to be chanted at the frequency listed beside it.
| Chakra | Solfeggio association | Seed mantra | Meditation theme |
|---|---|---|---|
| 01MūlādhāraRoot | 396 Hz | LAM · Laṃ | Grounding, security and stability |
| 02SvādhiṣṭhānaSacral | 417 Hz | VAM · Vaṃ | Creativity, emotional flow and openness to change |
| 03MaṇipūraSolar plexus | 528 Hz | RAM · Raṃ | Confidence, motivation and personal agency |
| 04AnāhataHeart | 639 Hz | YAM · Yaṃ | Compassion, connection and forgiveness |
| 05ViśuddhaThroat | 741 Hz | HAM · Haṃ | Expression, communication and authenticity |
| 06ĀjñāThird eye | 852 Hz | OM · Oṃ | Reflection, intuition and clarity |
| 07SahasrāraCrown | 963 Hz | Varies by tradition | Contemplation, unity and spiritual connection |
Frequency assignments: Meditation Music Library’s contemporary chart. Mantra sequence: Satyananda Yoga. These sources document teaching conventions; the chart’s themes are not demonstrated effects of individual tones.
The OM entry follows the cited Satyananda practice. Other chakra descriptions include different syllables and petal letters; the crown has no single universally prescribed mantra.
Understanding the differences
The specific frequency set was popularised in the late twentieth century. Its name borrows from solfège, the musical teaching system, but that does not establish these numbers as ancient Indian chakra tunings.

Some sound-bowl systems associate the chakras with C, D, E, F, G, A and B. Their frequencies depend on tuning and octave. One maker labels a 260 Hz C bowl for the root and a 345 Hz F bowl for the heart. That is the maker’s convention, not evidence of a biological correspondence.
A frequency, a key and a tuning reference are different things. A 345 Hz tone has 345 cycles per second. “Music in C” describes a key; “A4 = 432 Hz” specifies a tuning reference. A musical recording contains many frequencies, even when built around one drone. See the UNSW explanation of notes and frequencies.
The throat listening study uses a tentative 745 Hz notebook reading, not the 741 Hz Solfeggio assignment. The Ājñā collection uses 440 Hz as an editorial musical choice because its notes specify no frequency.
Reading the evidence
Music-based interventions can help with stress and some aspects of sleep and anxiety. This broader evidence does not establish that particular tones open particular chakras.
A 2018 study examined “528 Hz music” in nine participants and reported changes in stress-related measures. It did not measure chakra activation. Its small sample cannot establish a unique healing effect of 528 Hz.
These sounds can accompany a meaningful spiritual practice without being presented as a treatment or as a way to measure chakra health.
