Getting the draw reed to sound
Getting the draw reed to sound is the easy part of the overblow, all you need to do is resonate the right pitch. Again I would suggest you start with an isolated reed by blocking of the blow reed. Gently blow and try to find the right tongue/throat position that will allow the draw reed to sound.

It helps if you have a clear idea of what the note you are going to play should sound like. This helps set up the muscles in your throat for resonating the right pitch.

Remember this is not a matter of force, the isolated draw reed will sound at a whisper of a breath if you are resonating correctly.

You have to use the back of the tongue to resonate the pitch that the drawreed will make when you overblow it. Practice with an isolated reed first.

I don't seem to get the draw reed to sound.

When I have choked the blow reed, should I lift my tongue up a bit more or press it a bit down? Or something else perhaps? Btw, very good site, couldn't have gotten this far without you!

Hey Chris,

Many people can play bend notes and overblows with a tongue block. This might be useful for you in order to stabilise the tongue and keep the lips on the right spot. Of course it could also be that it is difficult to bend that way because it uses a lot of the throat muscles. But you should give it a try. You can also bend with the tip of the tongue, but that gives you a thinner sound.

just to clarify i meanth the back portion of the toungue not the bottom

I have cerebral palsy i am very saddened to relise that i cannot control the back of my toungue i understand now why i can't bent notes or over blow i also have to put my lipes ontop and bottom of the harmonica because i cannot keep my lips on the little lip hopefully you'll have some ideas cause i dont want to give up but if i cant get bends and overblows than i would consider giving up the harmonica.

i c control the tip of my toungbut when i try to move the bottom i lose the way i have my lips around the harmonica and my toungue goes in wierd positions.

any ideas?

Tinus,

Thanks, I followed your advice and it worked a treat. Exactly how you said. I wasn't choking the reed at all, just overpowering them. With the coverplate off and the 1 blow reed covered. The 1 overblow did eventualy sound. With a minute amount of pressure. No beetroot faced behaviour like in holes 4-6.

But minute, almost just a breeze and it sounded perfectly. That's obviously just the amount of resonance that the particular hole/key/instrument/my mouth combo requires. Seems I am going to have to mod the 1 blow after all to get it to choke properly now! ;-)

Thanks for all your help!

@G: have you tried opening the harp and just playing the overblown note while closing the blownote slot with a finger? It could be that you are overpowering the reed. You don't need force to get that reed to play, but you do need good resonance.
As far as tricks go I'd say: make as much room as you can. Drop that tongue to the bottom of your jaw and open up as much as possible.

Hi,

I'm a diatonic player, and about a year ago I bought a Suzuki Firebreath to learn Overblowing etc. Not being a harp modder I wanted an out of the box model, and so far so good. Sure the notes are still hit and miss affairs but I'm slowly approaching full chromatic.

I can overblow on 4, 5, and 6 and overdraw on 7 and 9 (and curiously 8 as well which gives the same note as a regular draw 9). So really I've achieved my objective. With the 6 OB and 7 OD I can get a 2 octave blues scale.

However, try as I might I just can't get a 1 hole overblow. I know it's possilbe, as you've shown us the way. And I can get the blow reed to choke but I just can't get the draw reed to sound: try as I might.

Now I'm nervous about tinkering with my 70 pound beauty so I was wondering, is there a trick to the 1 OB that I'm missing? Or a little mod that might help for the draw reed? As I said the blow reed chokes fine.

Thanks a lot man! Love the site.

G.

How do I reduce the air loss?
04-09-2009 12:22
When the blowreed opens the escaping air causes a change in the resonance qualities of your mouth/reed resonant system. When the blowreed is open you loose a little compression. Setting up the reed so that the loss of air is minimal when the blowreed is chocked helps a lot.

I am able to get the draw reed to sound on hole 4 when I block the blow reed and blow out; however if I unblock the blow reed I don't hear the sound of the draw reed or the blow reed. Why does this happen?

For those who are having troubles (as I have been) getting things in position for the right frequency of resonance, here's what's been helping me--finally--get some decent results, at least on holes 4 and 5. I start on the note *above* the overblow pitch I'm looking for, and then move my mouth as if I'm bending down a half-step while shifting to the lower hole.

For example, to hit the 5-hole overblow, which is a half-step below the 6 blow, I start with a 6 blow, then shift down to the 5 hole while imagining I'm bending that 6-blow pitch down a half step. This seems to get my mouth and tongue in the right position, as it's easier to "visualize" the right pitch coming off the overblow.

If I don't get it at first, I just keep going back and forth between the 6-hole blow and the "bent down" version of that note (the 5-hole overblow), adjusting the mouth-shape for the bend bit-by-bit until the right pitch emerges. Trying to keep the air pressure the same (relatively gentle) for the 6-blow and 5-overblow helps, too.

By the way, I'm making no conscious attempt to "choke" anything. When I tried to do that (say, by bending down the 5 blow in preparation for the 5 overblow), my mouth was not in the right position to resonate the draw reed at the *higher* pitch.

Finally, I seem to have the best luck when I start the overblow with a gentle "k" sound (from where the arc of my tongue meets the roof of my mouth).

Hope this might be useful to someone, and sorry if it just causes more confusion!

With a blocked blowreed you do not need to modify the drawreeds to get them to sound. Throat, mouth, tongue, it is all one system. You need to get it into the right position for sounding that note and yes that is exactly like singing. Everybody can do this, everybody that can hum a tune can do this. It apparently is a little easier to do if you can curl up the sides of your tongue, but since it can also be done while tongue blocking this is not required.
Hum, sing or whistle the note you want to play and your mouth/throat/tongue will be in the right resonating position.

One thing that might be a problem is that you are using too much force. If you try to use power to get the reed to play you will most likely fail miserably. With a blocked blowreed the amount of airflow you need to get the drawreed to sound is about as much as blowing into a candle flame at a short distance without it going out. Very gently blow and move your tongue from the palet down as in making a wheeeejo sound. Ending on the pitch you want to resonate.

I am having the same problems as cool guy and Rob. Even with the taped blowreeds, I cannot get a sound out of the drawreeds. Do I need to modify my harp (with a larger focus on modifying the blowreeds)? When modifying my harp, do I modify all the reeds or just the ones that overblow or overdraw?

Lastly, could you clarify what you mean by "resonating the right pitch." Is this at all like singing the right pitch (in terms of throat muscles)? Does everyone have the proper throat muscles to resonate correctly, or do you have to build those muscles with lots of practicing? It's also confusing, because Rob quoted your paragraph as "tongue/throat positioning," but your response to Rob indicate "tongue/mouth positioning." Is it really a combination of all 3 (tongue/throat/mouth positioning) that you need to get this to work? Please help!!!!!

No you should blow. It is only impossible if you use a valved harmonica. Otherwise you need to spend more time looking for the correct tongue/mouth position.

Tinus,
"Again I would suggest you start with an isolated reed by blocking of the blow reed. Gently blow and try to find the right tongue/throat position that will allow the draw reed to sound."

I tried to blow with the 'blow reed' blocked. This is quite impossible. Should I draw? or am I doing something wrong?

It could work on the tremolo but it won't be easy. In tremolos the draw reeds are in a seperate chamber from the blowreed. So there is no need to choke the blowreed, you just need to blow into the drawreed hole and overblow it. However since there are two reeds for every note, you have to overblow them both or isolate a single reed. Good luck.
31-07-2008 04:27
should this technique work in a 24-hole tremolo?
blowing on the draw reeds all I get is a super high whistle
thanks
26-07-2008 12:52
No the overblown note is always higher than the blow note. so it is the C that goes to the Eb. You bend down the C untill it chokes and then you play the overblow Eb on the drawreed.

Tinus Site, on your comment on 20-01-2006, did you mean the 5 hole overblowing an E to an Eb?

I just managed to get my 4 hole C down to a "B and a half" for the first time. Thanks for the help.

Although the bendometer is a good working tool, I do think that learning intonation visually, either with bendometer or a tuner, doesn't work too well. When you are playing you can't rely on visual cues for your intonation, you have to rely on your ear. so you have to train to adjust your intonation by using your ear, not by using you eyes. In my opinion it is better to train your intonation against a piano or keyboard. That way you learn to hear when you are off key

Bendometer. If you got an mike you can look at the Bendometer and know what note you are playing

Beautyfully written info. Thanks for love!

Okay, so it is not easy for everybody :)
However many people do find it rather easy to play the overblown note on a harp that has the blowreeds taped shut (or just on a single reedplate). I doubt that it is the harp that is the problem. It might be the force with with you are trying to do it. When the blowreed is closed of with tape or a finger, all the air goes directly to the drawreed. The drawreed only needs very little force and some good resonance to respond. If you try to put too much air through it it will choke, so try to play this overblown note very gently untill you find the exact position that resonates with it.

now way is this the easy part
i choked it real easy but i can only make it play the draw reed like barely ever and i cant replicate it
ugh
but maybe its just my harp
whatever this site is awesome anyway
14-12-2006 04:31
Great info !!
20-01-2006 01:50
Yes that would be the overblown note.

So if you are playing a C harp and are working on hole 4 that would be an Eb. The note produced by the draw reed when it is overblown.
19-01-2006 22:44
This page could be clearer about which note I'm trying to sound at this stage - presumably the overblow note for that reed pair?
