Singing bowl meditation: how to practise it

Singing bowl meditation is meditation with a singing bowl's sound as the focus: you strike the bowl once, or circle its rim with a wooden mallet, and keep your attention on the tone until it fades, then strike again. It is a kind of focused attention practice. In small studies people report feeling less tense afterwards, but a 2025 review rated every randomised trial at high risk of bias.

Fifteen ribbons in the deep blue Harmonance gives 852 Hz, the first tone on the Want to reflect page: they swing widest and burn brightest at the centre, then relax towards the edges, the way a struck bowl rings out.

What is singing bowl meditation?

Singing bowl meditation uses one sound as the anchor for your attention: the tone of a bowl, from the moment it is struck until it fades. Many kinds of meditation give the mind one thing to rest on, "such as breathing, a sound, a visual image, or a mantra", as the US National Center for Complementary and Integrative Health puts it (NCCIH). Here the sound is the anchor, and the bowl makes a good one, because it rings, changes and then ends on its own.

Researchers sort meditation into two broad styles. "One style, Focused Attention (FA) meditation, entails the voluntary focusing of attention on a chosen object." The other is open monitoring: noticing whatever comes and goes, "moment to moment" (Lutz and colleagues). Singing bowl meditation is mostly the first, with the bowl as the chosen object. As the sound thins towards silence, it can open into the second, and you start to notice the room, your breath and the quiet.

It is not the same as a sound bath. At a sound bath someone else plays many instruments around you, often for about an hour; in the practice this guide describes, you play one bowl yourself, for a few minutes, and your only job is to listen closely. For the full session, read what to expect at a sound bath; for the question of which tone to choose, read is there a best frequency for meditation?

How do you do singing bowl meditation?

Sit comfortably with the bowl in front of you, strike it once, and keep your attention on its sound until it has gone. Then strike again. Step by step:

Set the bowl down so it can ring. Rest it on a small cushion or on your flat palm. Striking or rubbing a bowl makes "the sides and rim" vibrate (Terwagne and Bush), so keep your fingers off them: anything touching the wall damps the sound.
Sit comfortably, and close your eyes if you like. In one study of a struck bowl, "All experiments were conducted with the participants who had their eyes closed." (Kim and Choi)
Strike once, gently. Tap the outside of the rim with a padded or wooden mallet. One study of singing bowl meditation used "a cloth-covered wooden mallet called a puja stick" (Goldsby and colleagues). A soft tap is enough; you can always strike a little harder next time.
Follow the sound down. Rest your attention on the tone and stay with it as it changes and fades. When your mind wanders, notice that, and come back to the sound. That is the classic instruction for focused attention: "to recognize the wandering and then restore attention to the chosen object" (Lutz and colleagues).
Wait for the silence, then strike again. A small bowl rings for most of a minute, as the measurements below show. Kim and Choi played their bowl "6 times for 5 min at intervals of 50 s", which makes a good first session.
Or circle the rim instead. For one long, steady tone, press the mallet lightly against the outside of the rim and circle it slowly and evenly, and keep going until the tone builds. It lasts for as long as you keep circling. The next section shows how the two sounds differ.
Finish in the quiet. When the last strike has faded, sit for a few breaths in the silence before you open your eyes. Five minutes is plenty to begin with.

No bowl to hand? The 852 Hz tone at the top of this page works as an anchor too, though it behaves differently from a bowl, as the last sections explain.

Should you strike the bowl or circle the rim?

Strike it for a bright, rich sound that fades; circle it for a purer, steadier hum that lasts as long as you keep going. Physics explains the difference. "Tapping excites a number of vibrational modes", while "rubbing excites primarily the (2,0) fundamental mode", the bowl's lowest way of bending (Terwagne and Bush). Circling works like a finger run round the rim of a wine glass: "A leather mallet can excite bowl vibrations via a stick-slip process, as does a finger moving on a wineglass." As the mallet drives that lowest vibration, "the lowest mode is excited along with its harmonics", true whole-number multiples of its pitch.

We measured one small bowl played both ways, from a public recording on Wikimedia Commons. Struck, it sounded six partials at once, and the loudest was not the lowest: its third partial, at 1,873 Hz, stood 17 dB above the 351 Hz partial at the bottom. Circled, the 351 Hz partial took over. Its octave appeared at 704 Hz, 27.5 dB below it, where the struck bowl had almost nothing, 49 dB below its loudest line, and the third and fourth partials fell more than 60 dB under it. Another recording, of a 4.5 inch bowl circled, shows the same octave: a 524 Hz tone with 1,049 Hz 30 dB below it.

Bars for one small bowl: struck, six partials between whole-number multiples; circled, its 351 Hz partial and 704 Hz octave; the steady 852 Hz tone — Struck or circled: the same small bowl, measured both ways. Struck, it sounds six partials at once, the loudest at 1,873 Hz, and none of them sits on the dotted whole-number multiples of its lowest line. Circled, its lowest partial, at 351 Hz, takes over and its octave appears at 704 Hz. Below, for comparison, the 852 Hz tone this page plays: one steady line.

So the two give you different things to follow. A strike gives a whole chord that thins out, the high partials first, down to a low hum. Circling gives one low tone with its octave above it, which holds for as long as you play. Quartz crystal bowls can be played the same way: in the session Goldsby and colleagues studied, they "were played by rubbing the rim with a felt cloth-covered mallet" (Goldsby and colleagues). If you are new to it, start by striking. Circling takes a little practice before the tone sings, and a strike gives the meditation a natural end.

How long does a singing bowl ring?

A small struck bowl rings for most of a minute, and its higher notes go first. We measured every partial of one strike of a 4.5 inch bowl, from a public recording on Wikimedia Commons, every half second. The lowest partial, at 361 Hz, fades by about 1 dB a second, so at that rate it takes 59 seconds to fall 60 dB, a millionth of its starting power. The fifth partial, at 4,094 Hz, fades by more than 6 dB a second and falls 60 dB in about 9 seconds.

At the strike, the first five partials start within 4.5 dB of each other, so the opening sound is bright and full. Each higher partial fades faster than the one below it, so the sound darkens as it rings, and the last thing you hear is the low hum. A larger bowl measured in Korea rang for a similar time: "Each percussion produces a sound modulated with a strong beat that lasts for about 50 s." (Kim and Choi)

Lines for a struck bowl's 1st, 3rd and 5th partials falling 1.0, 2.4 and 6.4 dB a second, beside a flat line for the steady 852 Hz tone — How long a struck singing bowl rings: one strike of a 4.5 inch bowl, measured every half second, each line falling from its own level at the strike. The higher the partial, the faster it fades: the 1st, at 361 Hz, loses about 1 dB a second, and the 5th, at 4,094 Hz, more than 6. The flat line is the 852 Hz tone this page plays, which holds its level.

Every partial of the struck bowl, measured
Partial	Fades by	60 dB down after, at that rate
1st, 361 Hz	1.0 dB a second	59 s
2nd, 999 Hz	1.5 dB a second	41 s
3rd, 1,868 Hz	2.4 dB a second	25 s
4th, 2,884 Hz	3.2 dB a second	18 s
5th, 4,094 Hz	6.4 dB a second	9 s
6th, 5,435 Hz	16.2 dB a second	4 s

That is the practical reason to wait between strikes: strike again too soon and you cut the low hum short. It also gives the practice its shape. The sound starts full, thins and ends on its own, and each strike is one round of attention.

What notes does a singing bowl play?

A singing bowl plays several notes at once, and unlike a string's, they are not whole-number multiples of the lowest. A plucked string's overtones sit at two, three and four times its note, which is why it sounds like one clear pitch. In the struck bowl we measured, the lowest partial sits at 361 Hz and the next five at 2.77, 5.17, 7.99, 11.34 and 15.05 times it: 999, 1,868, 2,884, 4,094 and 5,435 Hz. The small bowl in the diagram gave 2.84, 5.33 and 8.37 times its lowest line for the next three. That spread of notes, none of them in step with the first, is part of why a bowl sounds more like a bell than a string.

Physics predicts much of this. Terwagne and Bush simplify a bowl to a thin cylinder with a rigid base, whose rim bends into two, three, four and more lobes. From their equation for that shape, the overtones fall at 2.83, 5.42 and 8.77 times the lowest, then 12.87 and 17.71 (Terwagne and Bush; the arithmetic is ours). The measured bowls come within about 2 per cent of the model at the first overtone and fall below it higher up, a reminder that the model is a simplification of a real, curved bowl.

Look closely at the lowest partial and it is really two: 361.1 and 354.1 Hz, 7 Hz apart. No bowl is perfectly round: "Due to the bowl asymmetry, two peaks separated by several Hz arise and a beating mode is heard." Two tones 7 Hz apart fall into step and out again 7 times a second, so the hum swells and fades about 7 times a second. That is the slow wobble you hear as a bowl rings, and the sound bath guide draws it from another measured bowl. It happens in the air, so you hear it from any distance and without headphones, unlike a binaural beat.

Where do singing bowls come from?

The origin story you will hear most often is ancient and Tibetan, and even a physics paper repeats it: "Tibetan singing bowls are thought to have originated from Himalayan fire cults" (Terwagne and Bush). The evidence is thin. Writing in Tricycle, the Buddhist magazine, Samuel M. Grimes finds "There is no hard evidence that the sound bowls are ancient", and traces their first written record to an American album of the early 1970s. He asked a Geluk monk, who grew up in Kham and trained in a monastery in India, whether he had met the bowls (Grimes):

When I was in Tibet, I never saw those bowls that you hit and spin around the rim.

None of this changes how a bowl sounds or how you meditate with one. It does mean that a promise of thousands of years of Tibetan practice has no evidence behind it, and the sound bath guide follows the history further.

What does research say about singing bowl meditation?

Small studies find that people often say they feel calmer after time with singing bowls, but none shows that the bowl's sound, rather than resting quietly with your eyes closed, is the cause. Here is what each study looked at and found.

A 2025 review gathered 19 studies and rated every randomised trial among them at high risk of bias, mainly because people knew what they were getting: "Blinding is difficult in a trial, because it is hard to provide a placebo which is exactly the same as singing bowl therapy." It also found that "No adverse events related to singing bowl therapy were reported." (Cai and colleagues)

One trial did use a placebo. In Austria, 54 adults with a long-standing back complaint had six sessions with crystal singing bowls, six of a placebo session, or nothing. Both groups that had sessions came out ahead of the group that had none, and mood questionnaires suggested both sessions were relaxing, but the bowls did no better than the placebo: their effect "compared to placebo could not be confirmed" (Wepner and colleagues, in German).

Two small studies recorded brain activity. Kim and Choi struck a bowl six times over five minutes for 17 young adults with their eyes closed, and found the largest rise in brain activity at the bowl's own beat, 6.68 times a second. They had no comparison group, and argued that one "may be unnecessary or inappropriate" (Kim and Choi). Walter and Hinterberger recorded 34 adults through a 20 minute singing bowl massage, in which bowls are set on the body and played. "Overall EEG power decreased during the sound condition compared to a task-free resting state", which they read as "a shift towards a more mindful, meditative state of consciousness", while noting that "the sample size may limit the findings in generalizability" (Walter and Hinterberger).

The largest trial is recent and has gaps of its own. In India, 100 adults were randomly given either four weeks of daily, hour-long sound meditation in person, with bowls, gongs, bells and tingshas, or hour-long music sessions over Google Meet. The in-person group came out ahead on every measure the trial reported. But the two groups differed in more than sound: one met face to face and the other online. The sessions were also built mostly on a recording, a 528 Hz track, not on the bowls: "The recorded sound constituted the principal component of the intervention, while the acoustic instruments were used as complementary auditory elements." And the trial had support from a company, UNS Digital Technologies (Ravikumar and Sathyanarayanan).

Pitch may matter less than people think. Playing recorded bowls at three pitches to 59 adults, Oomen and colleagues found "no discrete effects related to the stimulus type or frequency" (Oomen and colleagues). And the hour-long study of 62 adults mentioned above, with bowls, gongs and chimes, is frank about its gap: "The most notable limitation was that this was a nonrandomized observational study without a control group." (Goldsby and colleagues)

Outside the lab, two small studies watched how people respond. In a Dutch nursing home, researchers sat in on 41 individual bowl sessions with 25 residents aged 59 to 97: "Two recurring behaviours were observed: falling asleep and entering an inner state of calm." (Konings and colleagues, in Dutch). In a nursing school, each class began with one short practice, a singing bowl among them. Students found the practices worthwhile, but "The response to mindfulness minute was most positive." (VanKuiken and colleagues)

What this does not show: that a bowl does something a quiet room and closed eyes do not, that one pitch works better than another, or that any effect lasts beyond the session. None of these studies tested the 852 Hz tone on this page. The fair reading is that singing bowl meditation is a simple, low-risk way to practise resting your attention on a sound, and in small studies many people say they come away calmer. For the wider field, read the science of sound healing.

Is singing bowl meditation safe?

For most people, yes, with two things to watch: your ears and how you feel. "Meditation and mindfulness practices usually are considered to have few risks." But a 2020 review of 83 studies, which the same NCCIH page describes, found that "about 8 percent of participants had a negative effect from practicing meditation", similar to the share reported for psychological therapies (NCCIH). If a session leaves you unsettled, stop, and choose something gentler next time.

For your ears, a struck bowl is at its loudest at the moment of the strike, as every line in the chart above shows, and loudest of all right beside it. Strike gently, keep the bowl at least an arm's length from your ears, and never strike one held next to your head. If you have tinnitus or hearing loss, or find some sounds distressing, strike more softly, sit further back, and stop whenever you need to. For how loud a room of bowls and gongs can get, and the World Health Organization's weekly limits, read the sound bath guide.

Can you meditate on a recorded tone instead of a bowl?

Yes. The practice needs a sound to attend to, not a particular instrument. Listeners ask about this under Harmonance's own videos. One wrote, under the 1.618 Hz golden ratio video:

How does this really work? Am I allowed to do my day job and listen to this or should I meditate on this sound?

Both are fine, and they are different things. Playing a sound while you work is listening in the background. Meditating on it means giving it your full attention for a few minutes and coming back each time your mind wanders, the same practice as with a bowl. Nothing stops you doing one and then the other.

A recorded tone behaves differently from a bowl. We measured the 852 Hz tone at the top of this page: it is one line at 852 Hz, with nothing else within 55 dB of it, and its level holds within 0.01 dB across its 20 second loop. It does not fade or swell, so you choose when each round ends: count ten breaths, or set a timer in Harmonance Studio, free once you sign in, so the sound stops without you reaching for it. To try it, press play above, or open the Want to reflect page, which gathers 852 Hz, 777 Hz and Jupiter. 852 Hz is one of the Solfeggio numbers, a modern set of tones: 852 Hz benefits: the claims and the evidence sets out what is and is not known about it, and the Solfeggio collection holds the rest of the set.

Sources and limits

The studies of singing bowls are small and short, only one of those here compared bowls with a placebo, and their participants knew what they were hearing, so expectation could explain much of what they reported. Our measurements describe three public recordings of small bowls on Wikimedia Commons and the recording of the 852 Hz tone this page plays. Other bowls ring at other pitches and for other lengths of time, and a recording carries its microphone and its room. Each fade rate is a straight-line fit to the level from just after the strike until the partial nears the noise of the recording (23 seconds for the first four partials, 12 for the fifth, 4 for the sixth), and the 60 dB times extend those rates rather than measure the whole fall. No study has tested the 852 Hz tone on this page, and our measurements describe the recording, not its effects.
