One-of-a-kind handmade singing bowl from The Ohm Store's curated collection
Each bowl in this collection is photographed and recorded individually — this is the exact instrument you'd receive.

A single well-chosen bowl can open a session. A transformative arc, the kind that moves a room from arrival to release, asks for more: a set built with intention, where each bowl's note, register, and character serves a specific moment in that arc.

That's why curating with precision matters when you're building a transformative arc rather than assembling a shelf of instruments. Every addition to your collection is a decision about what a moment in the session needs, and this collection is built for practitioners who shop that way.

01

The Bowl Your Collection Is Missing

If you're building a set and you know you need a D, an F#, or a B, you can filter this collection by exactly that note. Every bowl lists its note, octave, and cents measurement, so you're choosing against precise data, not "close enough."

Cents From CenterWhat It Means
Perfect pitch center for that note
Within ±10¢Still considered a true, perfect pitch note
Beyond ±10¢Audibly flat or sharp relative to the target note

A bowl listed as D at −3 cents will harmonize differently than one at +22 cents, even though both are technically a D. For a practitioner adding to an existing set, that difference is the entire point of shopping by cents rather than by note name alone.

02

The Note Is Discovered, Not Assigned

Every bowl in this collection is made by hand in the ancient tradition: hammered first, measured after. No bowl was made to hit a specific note. The note, octave, and cents value listed on each one is simply what that individual bowl produced on its own.

"The tuning of a bowl is a process of discovery and measurement after the fact, ensuring that your singing bowl is the only one like it that will ever exist." — The Ohm Store

Size Determines Tonal Character

Beyond note, size is the variable that shapes how a bowl actually behaves in a session, its register, its oscillation, and the role it plays in an arc you're building.

SizeRegister & CharacterBest For
Small (3–5 in)High, bright, portableFocused work, travel, the high voice in a multi-bowl set
Medium (5–8 in)Vocal range, strong oscillationMeditation, entrainment work, the most-requested range among practitioners
Large (8–14+ in)Deep, grounding, resonantGroup settings, session openings, the foundational bass voice

How to Listen Before You Buy

Every bowl is recorded individually, following the same two-step process, so you can evaluate it the way you'd evaluate it in person.

First, the strikeStruck with a red felt mallet — gives you the fundamental tone and initial resonance
Then, the rimSung around the rim with a suede-wrapped mallet — reveals the oscillation, the beating, pulsing quality within the sustain that practitioners look to when assessing a bowl's entrainment potential
Use headphones. The subtle beating frequencies and spatial qualities of each bowl are most audible that way.
Our Promise to You

The Love It Promise

We don't offer a standard 30-day return policy. We offer something more direct: you'll love the instrument you receive, or we'll work with you on an exchange or return. No fine print, no time pressure, just a commitment that the bowl you end up with is the right one.

Find the One That's Already Yours

Filter by note, by size, or by what speaks to you. When a bowl sells, it's gone for good.

The bowl your set is missing is 20% off while it's still here. Once it sells, this exact one won't come back.
