I have to admit to having a bit of a thing for the mouth harp and owned one years ago which I loved. I showed it to a little kid (kids are fascinated by them) who promptly broke it in two. Some 8 tortured years later I bought one from a guy at Woodford Folk Festival and thereby found out they come from Vietnam. When a friend went there recently on a cultural exchange I gave him $200 and begged him to bring back a stash and so he rode about the countryside on a motorbike making twanging noises at the locals and finally tracked them down. I have been getting them ever since.
I sell most of them at festivals and markets from my market stall and they appeal to all ages and walks of life. They seem to be hard to find elsewhere and usually only one type is available. I thought I should give them their very own page so here are photos and descriptions and sound samples of the various models I try to keep in stock:
Very small Fans of mouth harps 3-way $12 and 4-way $15. They are around 55mm in
length and pitched around an Fm7 chord. They sound strangely evocative and with
breath they kind of ring and distort and get louder, totally unique. Medium difficulty to
play and low intensity (you need a mike in noisy places to busk.) They come in wooden
cases and look like this and sound like this; 4-way fan


Treble Vietnamese brass mouth harp in bamboo case $10. Pitched around B, 75mm
long, efficient size for intensity & volume, easy to play and comfortable and you can get
all the sounds easily. This is how they sound; mini dan moi

Mid sized Vietnamese brass mouth harp in bamboo case $10. Efficient, loud, easy to
play etc. as above but bigger, pitched around F#, 105mm. Sound sample; dan moi

Bass Vietnamese brass mouth harp in bamboo case $12. Growlier and deeper, more
sustain, 115mm, pitched around Eb. Click this to hear it; bass dan moi
PNG style string activated mouth harp in wooden case $15. Hardest to play but unusual
didgeridoo-like soft attack, deep tone, and low pitched, around Ab.
Here is a sample; png style

Fish style bass vietnamese brass mouth harp for extra sustain (thicker metal) in a
wooden case $15 or new swivel case $17. Around B in pitch, deep tone with good tops.
To hear a short sample click here; fish


Large Vietnamese brass mouth harp on handle with wooden case $15 posted. Sounds the same as the Fish model but with handle to help with sustain and ease of playing.

Large Vietnamese brass double tined mouth harp; $17. My favourite all rounder which
has great tone, a little more volume, more clarity and just a bigger sound. It also comes
in a bamboo case in tribal fabric. 102mm, pitched around Eb and still easy to use. Here is
a sound sample; double tined dan moi

Here is a picture of the new triple tined version of the double tined mouth harp which
sounds awesome. It comes in a plain bamboo case with rosewood cap. $20. It is pitched
around B and is 115mm long. To hear click here; triple tined dan moi

There is also a thicker, more sustaining triple tined model in a swivel case which does
great vowels and is super loud. A little more difficult being quite wide but truly amazing
sound $20. It is pitched around B and measures 120mm. Sound; thicker triple tined dan moi

There is a slightly smaller and narrower triple tongue model made from thicker brass
and therefore much bassier with loads of sustain, tops and mids too. Also comes in a
swivel case for $20 and is pitched around E, 130mm. Click this to hear it;


Vietnamese traditional bamboo mouth harp $12. Medium difficulty
but nice mellower organic sound with less sustain that records nicely, not as
efficient as brass but decently audible acoustically. Varied pitch and colours.
Here is what one sounds like; small bamboo

Large bass Vietnamese traditional bamboo mouth harp $20.
The pre knobs forest techno 303 of bass sound, very low, strange, difficult, needs mic
and a bass amp to fully be felt but has a very rewarding sound. A huge 41cm long and
quite varied pitch around low E on a bass or lower.

Traditional Jaw/Jew's harp, brass and spring-steel, in inlaid case $35. The following
are the best quality traditional jaw harps I have played due to the tight tolerance
between the tine and the body. Beatifully made and great sound. This one is around F#
and measures 80mm.

The Flower model is bassy and classy and nice to hold and very comfortable on the teeth
being so heavy, $65. Best sounding jaw-harp, nice and deep. 115mm, around E.
There is also a small flower jaw harp which measures 98mm and is pitched around
E, $55.

The small jaw harp has the loudest sound being more intense at a higher pitch, $35.
Here is a sample; small jaw harp

The new ovoid shaped jaw harp is a beauty, nice tone, 75mm long, pitched around G
Plain bamboo case and rosewood cap; $35. Sound sample; small ovoid

There is a bass jaw harp as well, pitched around D $55.
Here is a short sample; bass jaw harp

There is another bass model which is chunky and very fat sounding and is my favourite
fat sounding jaw harp. It comes in a swivel type case, is pitched around E, is 90mm
long and has a real twang with good top end response, $60. Check out the sound;

A double brass jaw-harp with bass and treble tines on the same base, nicely in tune
with eachother around D and low G. Comes in a great swivel top pine and rosewood
magnetic case. $75. Hear it here; double jaw harp

There is a triple jawharp which sounds amazing and is in tune too which means you can
have three notes in one; low D, E and G. The bass note is the lowest I have heard. $85 in
a pine swivel top case. 4"x5"

The following two photos are of jaw harps made from rosewood, ebony and there is a
plexi-glass one too and they come in very swanky cases and sound great; nicely woody
yet still bright, the plexi-glass being the brightest. They are the most comfortable to play
too. $50. These are tuned to various notes and are different sizes.
Plexiglass in C; plexiglass jaw harp
Ebony in F; ebony jaw harp
Rosewood in E; rosewood jaw harp



There is a double version in rosewood or ebony for $70 and these are about D and a low G, measure about 10 x 15cm and a dream to use and to hear and it now comes in a swivel top case with a magnetic latch.
Click this to hear it; rosewood double jaw harp

The nose flute is the woodwind version and is held under the nose and the mouth cavity
shape determines the pitch. They come as a rosewood deluxe version and unfortunately
no longer with the bag $12 or a plain wood one for $5. Here is the sound; noseflute


The Mo Nhip; $5. This is the percussionists version, placed over the mouth and tapped
with the fingers. It sounds like this; mo nhip
Brass for the above came from recycling old U.S. ordinances (of which more were dropped on Vietnam than were dropped by both sides combined in WW1 and WW2!) so you too can be a part of what should be a growing industry of turning armaments into instruments. I want my missile warhead timpani now! Didge bazooka? Gun lyre?
These mouth harps have the best sound and the longest sustain of any I have seen. Top quality professional sound. They can be ordered wholesale too just email me at
ron(at)unheardofinstruments.comfor enquiries.
These ($Aus) prices are not including postage which is usually $4.20 within Australia.
O.S. is $8.80-20. I always do combined postage deals and special prices for multiple orders.
The fabric comes in various colours so feel free to ask for your favorite fabric and you can specify pitch too if you like.
HOW TO PLAY THEM:
People do ask so I thought I should write a quick note on the various techniques you can use and a basic guide for the un-initiated.
The jaw harp is played by holding the frame against the front of the teeth, making sure there is a sufficient gap so as not to hit the teeth with the tine (don't sue me for dental work on chipped teeth-use at your own risk.) The mouth harps are safer in this regard although careless use has drawn blood before. They are played by holding them against the front of the lips drawn over the teeth and held parallel. In both cases the best sound is with the fast moving part of the tine centered on the mouth opening and by getting a decent seal around the body to isolate the air on the inside of the mouth from the air on the outside. Striking the tine gently and inwards will get a better tone and prolong the life of the tine a lot, especially with the jaw harp, although rapid beats can be done by fanning it on the in and the out stroke. The fans I play with several fingers and a thumb plucking in both directions and using various patterns. Lots of fun.
The tonal variation is achieved by resonating different areas of the sinus and mouth and throat cavities the same way speech is produced. Vowels and consonants are audible but need not be spoken. Try bringing the tongue up against the back of the teeth to create a very small cavity- this will produce a high overtone. Descending through the overtone scale is done by subtly enlarging the cavity and finally the deepest tone is done by opening the oesophagus by dropping the adams apple down like when you try to say a very low 'er' sound. Opening and closing this, and/or breathing gently or by changing rapidly between tones can produce some wonderful vibrato effects and, particularly with the mouth harps, singing through it can break up the sound like with the didgeridoo. Great tonal variation is possible with a bit of practice and rhythmic and melodic elements can coexist in a tence inducing way but the main thing is to get a good groove happening so tap your foot or better still do a little dance - and have fun!
SOME ADVICE ON HOW TO GET MOUTH HARPs GOING IF IT PLAYS UP:
These can be a bit sensitive and they begin to rub and fizzle out if you warp them as the tolerance is minute. You don't have to play them hard to get a good sound and longevity-wise it is best too. Have a close look at it against a light background to see where it hits can help chose the right approach.
1 Try gently twisting it one way holding it at the extreme ends. One direction will make it worse the other may fix it.2 Then try grabbing it in the middle and stretching the outer edges outwards and away from the tine (sometimes this happens when it gets put back in the case on the wrong angle and it gets a bit squeezed or even applying excessive lippressure can do it, you only need to gently rest it on the front of the lips.)
3 Next try getting it flat as only a small kink (usually happens where the stiff bit ends) is enough to do it too.
4 If you are unfortunate enough to have bent one tine or worse both/all three, this requires gentle, tactful, patient bending/testing/bending...once it plays again then you will know to look out.
If it is almost there or if it has a feather of the brass flapping off the edge slight scraping along the sharp edges of the facing blades with something hard like a nail can cure it too but overdoing it kills tone..
I have gotten better at it but it can still take some time; don't give up, but you might have to put it down and come back to it.
It aint over until it bruk!
I usually have a good selection at Lismore and Byron Music, The Channon and Byron Bay markets and the Nimbin Happy High Herbs Shop, so come in and say g'day and try them out if you are in the area.
