The word gong covers instruments that have very little in common beyond being large, round and made of metal. An orchestral gong, a Chinese wind gong, a nipple gong from a gamelan and the flat gongs used in sound work all behave differently and are built differently. Buying without knowing which is which is how people end up disappointed.
Here is the plain version, and an honest account of where our own healing gongs sit within it.
Pitched and unpitched, the main division
The first split is whether an instrument produces a clear note or a complex wash. A nipple gong, with a raised boss in the centre, produces a definite pitch you could sing back. A flat gong produces a dense cloud of frequencies with no single note dominating, which is why it sounds enormous rather than musical.
The instruments used in sound work are almost always flat and unpitched, because the whole point is the wash rather than the note. That density is what people are describing when they say a gong feels like weather rather than music.
The tam tam, and what an orchestra uses
What most orchestras use is a tam tam, a large flat unpitched gong with a rolled edge, struck occasionally and hard for dramatic effect. It is closely related to what sound practitioners use, but it is built and played for a different purpose: a single decisive event in a piece of music rather than a slowly built atmosphere.
The difference in practice is mostly technique and mallet rather than metallurgy. A tam tam played with a soft mallet and built gradually behaves rather like a sound gong. A sound gong hit once, hard, sounds like a cymbal crash in a school hall.
Wind gongs and why they are not the same
A Chinese wind gong is thinner, with no rolled edge, and speaks quickly with a bright shimmering crash. It is a beautiful instrument and a poor choice for someone wanting the deep enveloping sound of a sound bath, because it has neither the mass nor the sustain to build that way.
Wind gongs turn up frequently in online listings aimed at the sound healing market, which is worth knowing before you buy from a photograph. If a gong looks thin, has a flat unrolled edge and is unusually cheap for its diameter, that is what you are looking at.
The planetary tuning question
You will meet planetary gongs, sold as tuned to the orbital period of Mars, Venus, the Earth and so on. The system comes from Hans Cousto, a Swiss mathematician who in the 1970s proposed converting astronomical periods into audible frequencies by repeatedly doubling them until they reach the range of hearing.
The arithmetic is sound. An orbital period is a frequency, and doubling a frequency raises it by an octave, so you can indeed arrive at an audible pitch from a planetary orbit. What the arithmetic does not establish is that the resulting note has any particular effect, or any meaningful relationship to the planet beyond the calculation itself. Plenty of players simply like how the tunings sound together, which is a perfectly good reason to own one and a rather different claim from the one usually made.
We do not sell planetary gongs, and we would rather say so plainly than let the phrase drift into our descriptions.
What we actually sell
Our range is traditional flat healing gongs, supplied in wooden stands, in four diameters. The 25cm and 35cm suit home practice and small rooms. The 50cm is for a dedicated space. The 80cm in an antique dragon stand is practitioner scale and the size you will have lain under in a class.
They are unpitched, built to be played with a soft mallet, and made to build a wash rather than produce a note. If that is what you came home from a sound bath wanting, that is the family of instrument you are after.
Questions people ask
What is the difference between a gong and a tam tam?
A tam tam is a large flat unpitched gong, the type orchestras use. It is closely related to the gongs used in sound work, with the main difference being how it is played rather than how it is made.
Are healing gongs tuned to a note?
Traditional flat healing gongs are unpitched. They produce a dense cloud of frequencies rather than a single note, which is what gives them the enveloping quality people describe.
What is a planetary gong?
One sold as tuned to a frequency derived from a planet's orbital period, following a system proposed by Hans Cousto in the 1970s. The arithmetic works, but it does not establish that the resulting note has any particular effect. We do not sell them.
Is a wind gong good for sound healing?
Not really. A wind gong is thin, bright and quick to speak, with neither the mass nor the sustain to build the deep wash a sound session relies on.
How do I avoid buying the wrong type of gong?
Check the description for flat and unpitched rather than nipple or wind, look for a rolled edge, and be suspicious of anything unusually cheap for its diameter.
