I attended my first tin whistle workshop on St. Patrick's Day Festival 2004, where Inis Fail's Luca Crespi taught me the golden rule: it must not be played like a recorder...
Like many beginners, I suffered from Whistle Obsessive Acquisition Disorder. The problem was, I couldn't find a whistle I really felt comfortable with. How can you possibly play an instrument you don't like?
In my view, the reason for WOAD is twofold. First of all, the poor quality of many low-cost whistles: you're forced to try out several whistles until you're lucky enough to find a good one. Secondly, I found out that whistles are not like recorders, which more or less share a similar sound. A Susato Kildare, a Dixon polymer and a Clarke Sweetone are completely different instruments, each with its own character and peculiarities.
Another problem is that I have a good musical ear, and I can't stand badly tuned instruments. This is often an issue with low-cost whistles.
I live in a smallish town in northern Italy, Verona (ring a bell? Shakespeare, Romeo and Juliet, the Two Gentlemen...), where the tin whistle is virtually unknown. Even Generations are difficult to find. When I eventually stumbled across one, it was a horribly out-of-tune, shrill, squeaky thing that put me off. I brutalised it until I made it playable, but I wanted something better.
The Dixon has a lovely tone but, in my humble opinion, is a bit too quiet in the first octave. The Susato is loud, but it sounds too much like a recorder! (I actually love recorders, but that's another story.) Both are reasonably in tune, but they could be better. I didn't like the sound of the Sweetone back then; now I do, but tuning is still an issue.
I wanted a whistle that was sweet and easy to play like a Dixon, but louder and cheap. Unfortunately, I couldn't find it. (Yes, I'm a fussy kind of person...)
A recent addition to my collection is the Dixon Trad. What a fantastic whistle! Had it been available back then, I probably wouldn't have tried to make my own. Read on, though...
Driven by frustration, I decided I'd try and make a whistle myself. However, I had no power tools like a drill, a bench vise, a lathe and what have you. Besides, most whistle making tutorials assume that you use copper pipe: hard luck, without proper tools! PVC is widely available though, so I decided I'd give it a try.
After some experiments (all of which, amazingly, produced playable whistles), I came up with a design that is easy to reproduce and works very well. I call it the `Low-Tech Whistle' because I only use very simple tools and materials.
Low technology, but high quality sound! Low-Tech Whistles in the key of D boast the following features:
Of course, there are defects, too:
If you're dissatisfied with cheap whistles, try to make a Low-Tech whistle. I'm confident to say that you'll get a very nice instrument. Furthermore, the design is very forgiving: it's almost impossible to fail.
Sounds too good to be true? Don't take my word for it, try it yourself!
The great thing about making your very own whistle is that you can get it exactly how you like it. You can customise everything to suit your needs: hole placement, loudness, type of sound, tuning. Moreover, you can't imagine the feeling when you realise that you've built an instrument that sounds better than several you find in shops!
Here is the list of materials and tools you will need for a Low-Tech whistle in the key of D:
In addition to the materials, you will need:
All of these items are cheap and commonly available at hardware stores. Craftsmanship and patience are within your reach if you're, say, 12 or older.
The PVC pipe I use has external diameter (e.d.) = 16 mm, bore = 13 mm, wall thickness <= 1.5 mm. It is used for electrical conduits. I suggest that you do not use pipe with bore larger than 13--14 mm, unless you want to make alto or low whistles.
It doesn't matter if you use different pipe: just make sure that you use thin (less than 2 mm) and stiff pipe. In fact:
I once thought that the material did not count that much, but evidence made me change my mind. Not all PVC pipes are created equal. I obtain consistently better sounding whistles using one brand, but you'll get reasonably good results with any brand of thin and stiff pipe.
Schedule 40 half-inch PVC pipe, commonly available in the U.S.A., might be too thick. Whistles made of this pipe are playable, but very breathy. Luckily, there's a solution; please see Dealing with Thick Pipe. Schedule 200 irrigation pipe is probably a better choice. Thanks to Floyd Brigdon for this information.
People also reported that CPVC pipe, used for hot water plumbing, works well. It's available at Home Depot and Lowe's stores.
In my opinion, using aluminium or copper pipe isn't worth the effort. They're much harder to work with, and you basically can't make a whistle unless you have power tools. Besides, I was given a couple of fine home-made aluminium whistles, and they sound exactly the same as my PVC whistles. (I expected them to be louder.)
Now you're ready to try this at home - better, in the garden or wherever it doesn't matter if you make a bit of a mess with PVC scraps and sawdust. But, beware:
Hacksaws, scissors and cutters have sharp blades. If you don't pay attention, you may slice your fingers: it hurts like hell. Take care, mind your fingers, wear protective gloves. And if you don't believe me, then ask my left thumb.
Also, do not breathe wood and PVC sawdust: I'm pretty sure it's not healthy.
You should be aware that PVC might be dangerous for your health. Please have a look at the Wikipedia page on PVC.
However, I talked to a chemist friend of mine and asked for his opinion on the matter. He said that all PVC pipes sold in Italy are chemically inert. They must be extremely stable, as they must last decades embedded in walls. Therefore, it's very unlikely that a whistle made with this PVC will release nasty chemicals.
The following figure shows the names of whistle parts:
The most important part of a whistle is the mouthpiece. Its dimensions define the sound of the whistle:
Take this information into account when you decide what your whistle will sound like.
Other factors influence the whistle volume. Big holes make the whistle loud, small holes make it quiet. A whistle with a small window and big holes will sound louder and sweeter than a whistle with a big window and small holes. Blowing harder also increases the volume and sharpens the pitch! When you tune the whistle (see below), you'll have to decide how hard to blow it.
For any given pipe bore, the lower the key (that is, the longer the pipe), the quieter the whistle. Instead of just enlarging the windway, you should experiment on the width-to-length ratio of the window. For example, on a C whistle an 8 x 5 mm window produces a much better sound than a 10 x 4 mm window.
Let me start this section with a witty remark by whistle teacher Brother Steve:
...in general, people with perfect pitch do not take up the tin whistle!
The same concept is stressed upon by a renowned flute maker, Doug Tipple, who writes in his flute pages:
I believe that some people have unreasonable expectations about pitch and intonation. They think that their $20 electronic tuner set to equal-temperment is the gold standard and that any variation from ``dead-on'' pitch accuracy is not acceptable. To the contrary, my attitude with regard to flute performance is to lay perfectionism aside and accept some variations in intonation as inescapable and perhaps even a good thing.
I quote these wise words completely. In fact:
Due to the physics of the instrument and the way it's played, cylindrical whistles cannot be exactly in tune. And don't complain: uncorrected cylindrical flutes are even worse, not to talk of bagpipes.
First of all, the player's blowing pressure can alter the pitch of a note by a third of a tone, or even more. Secondly, with cylindrical whistles the second octave is slightly flatter than the first octave. Third, the whole tuning is affected by air temperature.
Fourth, and this may sound strange to you: a few notes should be tuned purposedly flatter than their "right" pitch (G and C sharp on D whistles, for instance). This way they will sound better. It's a complex subject called temperament.
All this blurb to support my opinion: checking each note on a chromatic tuner is not a great deal. I suggest that you use the tuner for only one note: the key note of the whistle in the second octave. For example, the second D on whistles in the key of D; you'll tune the other notes by ear. Trust your ears! Take your favourite blowing pressure into consideration, and warm up the whistle for at least 20 seconds beforehand.
Finally, bear in mind that high-pitched notes stand out much more than lower-pitched notes. While flat high notes sound really horrible, sharp low notes may go nearly unnoticed. Keeping all this in mind, you may want to tune the second octave D (or the equivalent base note) just a bit sharp, e.g.\ 5 cents. The second octave will sound in tune, the first octave will sound slightly sharp.
A first approximation of the hole positions is given by the following table. It specifies the hole positions as a percentage of the lip-to-foot length, calculated from several soprano D whistles I made. For example, the first value (42%) is calculated as:
distance of first hole from the lip / lip-to-foot distance.
This table is just a rough approximation! Actual hole positions may differ by several millimeters! Besides, different tables apply for soprano, tenor and low whistles. As far as I know, there is no "perfect" formula as there are many factors involved.
In the following plans, all measurements were calculated for whistles whose central note is exactly on pitch. Unit is millimeters. Click on the images to download a PDF version of the plan.
If you want a session-grade whistle you can blow harder, add 2 mm to each figure. That is, add 2 mm to the whistle length and 2 mm to the distance of each hole from the lip.
Here's a mm-to-inches chart, kindly provided by Stuart Wier:
By request, here is a "whistle-chanter" in Bb. It is designed to be played using the same closed fingering as a GHB chanter:
These whistles in the key of D provide an additional bottom hole for playing C sharp or C natural. Beware: the bottom D is weaker than in a standard whistle!
Starting from the key of C, you will want to use pipe of wider bore (I switch to 20 mm e.d. pipe). Conventionally, whistles in the key of Bb down to G are called "Alto whistles". Wider-bore whistles are louder and have a much stronger bottom note, if you rig the fipple as explained in Section Rigging the Fipple:
Still wider bore is required for Low whistles, which conventionally start from the key of F down to low C or even Bb. Moreover, the window should be enlarged a bit. I use 25 mm e.d. pipe.
The following table provides the hole positions for low whistles, as obtained from my low D:
The length of the low E whistle is WRONG (it's the same as the Eb low whistle). As time permits, I'll fix it.
This picture shows a low C, a low D, and a soprano D whistle:
This is the fingering chart for the model in the key of D (PDF version here):
These measurements are not carved in stone. Other factors may influence the tuning, such as pipe thickness, type of PVC, window size. Please take them with a pinch of salt. In particular: if the bore of your pipe is less than 13 mm, the whistle will be a few millimeters longer; and vice versa.
To some extent, the hole positions and diameters may vary. I'll give you the measurements I chose for my own convenience, but feel free to experiment. The basic rule is: if you move a hole upwards (i.e. closer to the mouthpiece), you'll have to reduce its diameter; and vice versa. This rule allows you to adjust the holes' positions in order to make the whistle more comfortable to your hands. Besides, if you make a mistake positioning a hole you'll be able to correct it by varying its diameter.
Have a look at these two whistles. They are tuned exactly the same, but one has a small window, small holes and is even shorter than the other. It's a quiet whistle, and I call it the `lager' as opposed to the `stout', that is a louder whistle. Notice that the holes are placed differently in each whistle.
Lastly: your first whistle will probably take more time to make than the second. Don't worry, don't rush. Have fun.
The following instructions assume that you are going to make a standard whistle in D, with a 3-cm-long mouthpiece. If you want to make a whistle in a different key, the only difference is the length of the initial PVC piece. For instance, for a whistle in C add 3.5 cm.
Please bear in mind that boring the holes is the easiest part of the job. The tricky part is making the mouthpiece! Also, do not take measurements from the pictures; use the drawings above.
I suggest that you read all the instructions before you start. All pictures were taken during the actual construction of a whistle.
First of all, you will want to make square cuts. It's fairly simple:
And now, go ahead!
After sawing the PVC pieces to measure, make all ends, edges and sides smooth and well polished.
You may make the fipple block top parallel to the bottom, but if you make it tapered as shown by the green line in the drawing some Bernoulli effect will occur. That is, the air flow will accelerate near the lip, increasing the whistle responsiveness and lowering air requirements. It will produce some backpressure, too. Take care not to blunt the fipple end!
I'll remind you again here. 8 mm wide windway = small window = less air required, quieter and pure sound; 10 mm wide windway = big window = more air required, louder and very slightly breathy sound. Your choice.
Again, make all edges perfectly clean. It is essential that you make the lower edge of the lip a perfectly clean and even arc. If you wish to apply the Bernoulli effect, the section to cut out should measure 10 (mouth end) x 8 (lip) mm.
Peek through the windway: if the fipple block has the correct size, you should see a hairline space just below the lip - say, the thickness of two or three sheets of paper. If you don't see this little space, the sound will be weak; sand the top of the fipple block as needed. Beware not to sand too much, or the whistle will consume more air and the second octave will sound harsh. As little as 1 mm may be too much!
If you bore only the bottom three holes, and move the third hole to the back, you make a tabor pipe.
You may want to make two whistles with different sounds, which I call the `stout' and the `lager'. The `stout' whistle is loud (window dimensions: 8 x 5 mm), has some backpressure and is good for outdoors or session playing. The `lager' whistle has a more delicate sound (window dimensions: 7 x 3 mm) and it gives its best at playing airs.
To get a hint of their volumes, my `lager' is approximately as loud as a Sweetone, while my `stout' is almost as loud as a Susato. But it still sounds like a whistle...
Surely, now you want to hear what the Low-Tech Whistle sounds like. There you are a few sound clips; please don't expect dazzling virtuosity, I'm just a beginner and I recorded these in a hurry... In some cases I skipped repeats:
No audio effects were added.
As I stated above, when the pipe is more than 1.7 mm thick, the sound will become too breathy. One possible solution is to make the windway thinner. This can easily be done by glueing a bit of plastic sheet under the windway cap. I found that plastic obtained from notebook covers works best.
Cut out a rectangle that is as wide as the curved windway. It can be as long as the windway cap, but I suggest that it be shorter to produce some Bernoulli effect. Trim the part that would extend over the window. If you need to fine-tune the windway height, Teflon tape is recommended.
A simpler but more effective solution is make the window smaller, say 6 x 5 mm. Thanks to Phil Hatmaker for this trick.
A completely different fipple design is outlined by R. Jay Goos in his page: http://rjaysplace.com/exofipple
In his excellent (flute pages, a gentleman called Rick Miller suggests a technique for improving the feel of a PVC flute under one's fingers. His technique consiss in chamfering, i.e. grooving the holes.
I tried this techinque on my whistles, with interesting results. As shown in the picture, I rolled some fine-grained sandpaper around a length of pipe. Then I used this round file to sand a groove centered around each hole. The finger pads rest more comfortably against the grooved holes.
As a welcome side-effect, the tone seems to improve a bit due to smoother holes. Tuning is not affected.
When you make an alto or low whistle, the fipple and lip need an important modification:
These tricks were kindly provided by Jem Hammond. Thanks!
Making a whistle tunable is straightforward. There are several ways I use: a quick-and-dirty hack, and two ``professional'' methods. Other methods involve hot air guns or boiling water, which may work on some pipes. It didn't work on the PVC pipes I tried, but you might be luckier. Here is what I do:
This method is only effective if your whistle is slightly sharp to begin with.
While playing a G, slowly slide your finger over the whistle window. The sound will go flat, then the volume will start to decrease. Modifying the window size is the simplest way to tune a whistle.
Using a small ball of poster putty to partly cover the window will do the trick:
With a bit of luck, you should be able to find some plastic pipe with bore equal to the outer diameter of your whistle. Cut out a 3 or 4 cm long piece, which we shall call the tuner pipe. Then - highly traumatic moment! - saw your whistle in two parts, halfway between the lip and the uppermost hole. Insert the two whistle parts in the tuner: if they fit tightly, you're done; otherwise, roll some adhesive tape around the whistle ends. I actually glue the upper part and tape only the lower part for better stability.
Pipe connectors are usually available for any pipe size. I tried with the ones available in Italy but they didn't work well for me, because they have slightly conical bore. Again, you might be luckier than me.
A piece of PVC pipe can be softened and expanded by soaking it in acetone. A 1-litre can of acetone costs around 5 Euro.
After half an hour or more in acetone, PVC turns to soft rubber and expands. When the pipe has expanded enough, wash it under running water, then fit another piece of pipe in the expanded section. I recommend that you apply some cork grease and/or wrap some paper around the pipe.
It takes several hours for PVC to harden and shrink back a bit, possibly up to two days or even more. At the end of the process, you will get a tight fit between the two parts. One of them will become the whistle head, the other the whistle body. Never leave the two parts separated for long, because the expanded section may shrink too much.
Apply some cork grease again, and enjoy your tunable whistle. Also, bear in mind that acetone removes plumbing marks quite easily.
I spend most of the time shaping the fipple block. If you manage to find wooden (or plastic) sticks that have the same diameter as the bore, you'll save yourself a lot of work. You may ask a carpenter who has a turning lathe.
Furthermore: if you have a drill press and the right bits for wood, boring the holes will be a matter of minutes. The slower the drill, the better the holes.
The mouthpiece holds together even if you do not glue the fipple block and the windway top. Once you've played the whistle for a while and are satisfied with its sound, you may glue the fipple block into place; but if you don't, you'll be able to adjust the fipple block position as needed.
I strongly suggest that you do not glue the windway top. By moving it closer to the lip, you'll be able to make the whistle quieter; moving it farther will make the sound breathy.
The curved windway is, by design, less affected by the well-known moisture effect. I have never had one of my whistles clogged by condensation, but the wooden fipple block does absorb some moisture. As a result, the space under the lip space reduces and the whistles looses volume.
The problem is easily solved if you apply some cork grease on the fipple block top. Cork grease, commonly used for woodwinds, is cheap and is available at any music store. Remove the windway top, grease the fipple block, then put the windway top back on.
A better method is boiling the fipple block in melted candle wax for a few minutes. Air and humidity will be replaced by the wax, which is impervious to moisture. If you choose this method, beware: some types of wood will shrink! This can be an advantage and save you some sanding.
The same mouthpiece can be used for two whistles, one in D and one in C:
Although I bet your first whistle will be a perfectly playable instrument, errors might occur; or you may want to make some improvements. These are the most common cases.
Remove just a little, check the bottom note, and repeat if needed. You may like to cut the foot so that its section becomes an ellipse instead of a circle.
I wish I could get 1 Euro each time people ask me.
Simple answer: just try. Good ol' trial and error. There's no trick!
If you can't find PVC pipe having the very same geometry as mine, don't worry:
In my opinion, it's a dumb idea.
A thumbhole is used in recorders to get notes in the high register, but whistles are smarter in this respect: just blow harder. A thumbhole is completely redundant in a whistle. So, why bother?
Excellent! Aren't you happy?
Seriously, if your whistle has a recorder-ish sound, all you have to do is slightly blunt the lip.
Sorry, I can't.
I tried to write the instructions as clearly as I could, but I have only a limited command of the English language, and I'm afraid I can't explain how to make a whistle any better than I did. (Come to think of it, I couldn't write better explanations in my native language (Italian), either.)
To put it bluntly: if you don't understand something, tough! You should seek help from whistle forums, such as a Chiff and Fipple. Besides, the purpose of this guide is to encourage everyone to experiment, not to encourage everyone to ask me...
Every now and then, people ask me how to make a whistle that plays in the Gyzragyan or Putzyculian scale; or how to implement alternative fipple design; or about very long or thick pipe, hyperbass whistles, alternative materials, whistle-like instruments, or to solve weird problems, and so on so forth.
If it's not already explained in this guide, I'm afraid I'm totally helpless! Please don't expect me to be a guru with the ultimate question to every aspect of instrument making. I'm just a poor lad who happened to write a simple how-to guide, but that's all. :-)
Now that you have a whistle, it's time to play some music. Being a beginner, I turned to the Internet for tutorials and collections. There are lots of sites dedicated to the whistle!
I found the following tutorials very useful:
Next, I downloaded excellent tune collections from these sites:
Most tune collections are written in ABC. If you want to know more about the ABC music notation, please refer to these official sites:
I maintain the latter site, where you can find ready-to-use software and documentation.
Since I published this guide on the net, I have received a lot of feedback. It looks like my instructions work! Here is what Kyle Stuart from California wrote me:
Guido: I just want to thank you for posting the directions on making the low tech whistles. On my third try, I was able to produce a magic whistle in the key of soprano D. This whistle cost less than a dollars worth of materials and is far superior to ANY whistle I have ever purchaced. And I have bought quite a few.
(Reproduced by kind permission. Thanks!)
I had no doubts about the quality of the sound of the LTW, but now I have a confirmation. Please read the review available at http://www.tinwhistler.com/music/reviews/srcreview.asp?keyword=lotech. Many thanks to the Wandering Whistler for the review.
A review of my Low-Tech Low D was published on Chiff and Fipple.
Also, I was flattered when Keith and Sandra from Canada wrote the following:
I'm *shocked* at your suggestion I should tell my friends I'm playing "a piece of electrical conduit". They and I already refer to your progeny as "The White Lady of Verona". She is never far from my lips. She is so shapely, light and responsive; even more so after a few minutes of warming up... She loves to play and has captured my heart and mind. I can't keep my hands off her...
(Reproduced by kind permission. Thanks!)
Please let me know what you think of this tutorial; suggestions are always more than welcome. And if you make a whistle you like, I'll be glad to hear it!
All the information in this guide may be freely used for any purpose. If you sell whistles you make using my directions, good for you! But I ask you to play fair and give me proper credit. Please point your customers to this page... and send me one of your whistles for my collection.
Wayne Hubin from Watertown, Minnesota, wrote me some of the most rewarding feedback I could hope for:
I'm sending this note to thank you for the whistle design and detailed and comprehensive instructions provided on your web site. I work with orphan children in Russia with a team of Americans that I lead each year. We do many things with the children and this year one of the projects I wanted to do was whistles for the kids (65). Imagine my delight when I came across your web site. In short, I ended up making 80 whistles (4 models) and had the children complete and decorate them at the orphanage. Trust me it was quite a chorus. I also made 6 different models for my own use as well. Thank you for making this project possible.
Draven Blaze from Kentucky moved me to tears as he wrote:
Thank you so much for being so generous as to go through the though and effort to learn how to make the LTW and then give the instructions away.you have given this disabled Veteran an activity that i can do with my kids where I'm unable to others.Words can't say how much you have made me happy.
This is the ultimate reward I could ever dream of!
The whole point of this guide is enabling anyone to make their very own whistle. For a while I thought that selling my whistles was against the spirit of the thing, but I realise that some people may be less industrious than I am.
I warmly recommend that you try and make your own, but given that some people asked, I will sell Low-Tech Whistles on request. Please go to my other site, http://www.ggwhistles.com.
