Red Doors Studio
A centre of calm on the 21st floor, built around Asia’s largest collection of meditation gongs. We bring ancient, time-tested practices of deep relaxation — gongs, labyrinth walking meditation, Kundalini yoga — to a city that rarely stops.
New to this? You lie down, covered and warm, and do nothing at all for about 45 minutes while the gongs play. No experience needed.
Four ways in
Studio events
New moon and full moon gong baths, gong training, private and small-group sessions, all-night pujas.
Public events
Festivals, museums and partner venues across Hong Kong and the region.
Corporate
Sound sessions brought to your office, offsite, conference or client event.
Shop
Gongs, bowls, chimes and mallets — the instruments we play, and the ones we teach on.
Five moments
No experience needed and nothing to prepare. This is the whole of it.
-
15 minutes early
Shoes off at the red door
Take the lift to the 21st floor and leave the city at the door. Nothing to prepare.
-
Settle
Find your place on the floor
A mat, a blanket, an eye bag. Wear something loose and warm. All of it is provided.
-
Intention
A guided meditation
A short themed meditation to begin. Your breath slows and the day loosens its grip.
-
About 45 minutes
Then the sound arrives
It builds into a wash you feel in your chest and through the floor. Thoughts thin out.
-
Return
Spiced tea and brownies
Come back in your own time, then stay a while before heading out into the evening.
What that feels like under the gongs
The sound starts so quietly you cannot place where it is coming from. Stroke by stroke it builds, until the room is a single wash with no obvious source and no rhythm to anticipate. That unpredictability matters: there is no pattern for the mind to lock onto, so it stops trying.
Thoughts thin out. You lose track of how long you have been there. Some people fall asleep, some see colour behind their eyes, some find a wave of emotion arriving without a reason attached to it. All of it is normal and none of it is required.
Most people leave content, clear headed and lighter than when they arrived.

In their words
... mind-blowingly unbelievable.
Read it all
Martha’s musicianship, sensitivity, and hospitality are world class. It’s been over a week since I had the opportunity to experience a gong bath with her, and the response I posted on social media that evening says it all: I have experienced sound baths. I have given sound baths. I have a deep appreciation for what sound can do to the mind, body, and soul. But I just got out of a gong bath by Martha Collard (of Red Doors Studio) that was mind-blowingly unbelievable.
I cannot thank you enough for sharing your exceptional, unique, and powerful expertise.

Not a day goes by, Martha, without me hearing from someone who attended the Global Wellness Summit in Singapore that your gong baths and main stage performance changed their lives. I think it’s fair to say you were the talk of the summit, and that’s quite something. It’s particularly noteworthy because our audience, as you know, is invitation-only, C-suite executives, mostly running multinational corporations. For them not just to experience what you offered, but to be so moved by it, is a testament to the power of what you do.
I wasn’t prepared for how compelling the gong would be as an instrument for transformation.

Martha opened the world of the gong to me. As a player of metal Tibetan-style bowls, I wasn’t prepared for how compelling the gong would be as an instrument for transformation. I’m excited for this entirely new territory that promises so much.
I now understand the art and science behind the gong.

Fabulous course. Beyond expectations. Martha’s knowledge, enthusiasm, patience, and preparation all came through. I absorbed a lot during this class. I now understand the art and science behind the gong. I seek to play a gong musically, and for healing. Using Martha’s techniques and the homework introduced in this class, I found how soothing and enlightening the gong can be.
... enlivening my body’s cells, and raising my vibrational energy.

Martha’s intro course and gong-playing practicum course took me from knowing very little about gongs to buying one and playing it daily for calming the nervous system, spiritual focus, enlivening my body’s cells, and raising my vibrational energy. Thank you, Martha, for elevating us all!
She articulates complex acoustical principles with remarkable clarity.

The field behind this page is real.
It is not a video and it is not decoration. Around 65,000 grains are being solved against a standing-wave equation, live, on your graphics card — the same equation that governs sand on a vibrating plate. It has been running behind every word you have read so far.
This side of the page is why that matters.
Turn back the way you came, or press ← and →.
Everything vibrates.
Sound is not a feeling and it is not an idea. It is motion. A struck gong pushes the air around it into travelling waves of pressure, and those waves push back on everything they meet: the wall, the floor, the water in a glass on the table.
They also push on you. A human body is roughly sixty per cent water and held together by tissue and bone, all of which carry a pressure wave rather well. Low frequencies in particular pass straight into you: a large gong is felt in the chest, the hands and the floor a moment before it is recognised as a sound at all.
Strike it. Click anywhere on the strip. Watch one dot rather than the whole row: it only shuffles back and forth about its own place. Nothing travels across the strip except the squeeze.
You do not only listen to a gong. You are moved by one — mechanically, measurably, whether or not you are paying attention.
Vibration takes a shape.
Scatter fine sand across a metal plate and draw a bow along its edge. The plate bends into a standing wave: some parts of it shake hard, and between them run lines that barely move at all. The sand is thrown off everything that moves and gathers along everything that doesn’t — and a precise geometric figure appears out of nowhere.
Change the note and the whole pattern dismantles itself and reorganises into a different one. Ernst Chladni published these figures in 1787. They are not an illustration of an idea. They are the shape of a frequency, made visible in matter.
Nature is full of the same family of behaviour, because resonance is not a special case — it is what happens whenever a repeating force meets a material with a shape. Ripples ribbing a beach at low tide. The banding across a dune. Standing waves crossing a pond. Sound, water and sand all keep running into the same geometry.
Hover a pattern and the field behind this page holds it. Move away and it goes back to following your scrolling.
You can also drag the cursor straight through the field to disturb the grains, and the sound toggle bows a violin at whatever frequency the plate is currently holding.
It isn’t only psychological. It’s physical.
This is the part that usually gets lost. A gong bath is described as relaxing, as though the effect were a mood — something you talk yourself into while lying on a mat in a dark room.
But the mechanism demonstrated on the plate does not stop at the edge of the plate. Sound moves matter. You are matter. The grains reorganising behind this page are not a metaphor for what happens in the studio; they are a visible, slowed-down version of the same event, at a scale you can watch.
That is the foundation the whole practice rests on. Everything else — the room, the mats, the forty-five minutes, the instruments themselves — is engineering around one fact: a body in a field of sustained low-frequency sound is being physically driven by it.
One note, sweeping. Each object answers only near its own — the same push does nothing to the rest. Drag it yourself, or leave it alone and it sweeps.
Where the line sits. That sound physically drives the body is not in question — it is the same mechanics as the plate. What that does for any one person is where honest language matters. What is consistently observed is a shift in the nervous system that deep, sustained, unpredictable sound produces: breathing slows, arousal drops, and attention loosens from the alert waking state towards something closer to drowsing. What people report afterwards is a different quality of rest from simply lying down in silence. We would rather tell you that than promise you more.
Ancient knowledge, for a modern problem.
Chronic stress is a nervous system that never gets the signal to stand down. Hong Kong is very good at producing it: long hours, dense living, a phone that never stops. The body keeps running the emergency programme long after the emergency has passed.
Long before anyone had that vocabulary, cultures across the world built instruments for exactly this — gongs, bowls, chant, drums, the deliberate use of sustained sound to move people out of one state and into another. They arrived at it empirically, over centuries, because it worked.
Red Doors exists to make that available here, properly: with the right instruments, in a room built for it, run by people who have spent years learning to play them. Not as a mystery, and not as a claim. As something you can lie down inside and judge for yourself.
