If you've spent any time playing this double reed instrument, you know that learning how to make bassoon reeds is basically a rite of passage. It's frustrating, messy, and occasionally makes you want to throw a piece of cane across the room, but there's nothing quite like the feeling of playing on a reed you built with your own two hands. Plus, let's be honest: buying handmade reeds from professional makers gets expensive fast.
Making your own reeds gives you total control over your sound. You can tailor them to your specific embouchure, your bassoon, and even the altitude or humidity of where you're performing. It's a craft that takes years to master, but the basics are actually pretty approachable if you take it one step at a time.
Getting your toolkit together
Before you even touch a piece of cane, you need the right gear. This is usually the part where people get a little sticker shock. Bassoon reed-making tools aren't exactly cheap, but they last a lifetime if you take care of them.
At a minimum, you're going to need a forming mandrel, a drying rack, some brass wire (usually 22-gauge), a pliers-and-wire-cutter combo, and a shaper tip. You'll also need a very sharp reed knife. I can't stress the "sharp" part enough—a dull knife is your worst enemy and will lead to ragged cane and sore thumbs.
Beyond the hardware, you'll need some consumables like cotton thread for the turban and some waterproof glue or Duco cement. Some people use heat-shrink tubing, but if we're going old school, thread and glue are the way to go.
Choosing and preparing the cane
Most beginners start with "Gouged, Shaped, and Profiled" (GSP) cane. If you try to start from raw tubes of cane, you're going to need thousands of dollars in heavy machinery, and honestly, life is too short for that when you're just starting out.
When you get your GSP cane, look for a nice golden-yellow color. If it's green, it's too young; if it's dark brown or spotted, it might be too old or brittle. You want a straight grain that runs the length of the piece without any weird twists.
The big soak
You can't work with dry cane—it'll just shatter. You need to soak your cane in warm water for at least 20 to 30 minutes. Some people soak it overnight, but that can sometimes make the fibers a bit mushy. You want the cane to be pliable enough that you can fold it without it cracking down the middle.
Folding and forming the blank
Once your cane is nice and hydrated, it's time to get to work. First, you'll find the exact center of the cane and give it a tiny score mark. This is where you'll fold it. If you've got a "shaper," you might refine the shape here, but if you bought GSP cane, it should already be ready to fold.
When you fold the cane over a mandrel or an easel, make sure the "ears" (the sides of the reed) line up perfectly. If they're crooked now, the reed will be a nightmare to play later.
Placing the wires
Now comes the "construction" phase. You'll place three wires on the reed. The first wire goes near the top of what will become the throat, the second wire about 8-10mm below that, and the third wire near the bottom where the bark ends.
This part is a bit of a balancing act. You want the wires tight enough to hold the shape, but not so tight that they crush the cane fibers. Using your pliers, you'll twist the wire ends and trim them down. It starts to look like a real reed at this point, which is always a good feeling.
Forming the tube
This is the most "violent" part of the process. You need to take your forming mandrel and jam it into the bottom of the folded cane to create a circular opening. Since the cane is wet, it should stretch and take the shape of the mandrel.
If you hear a loud crack, don't panic—usually, a few small vertical cracks in the bark are totally normal and even necessary for the tube to round out. However, if the crack goes past the second wire into the blade, that piece of cane is now a very expensive toothpick.
Once the tube is formed, you'll leave it on a drying rack for several days. Don't rush this. The cane needs to "remember" its new shape. If you try to finish a reed while it's still wet from the initial forming, it'll just collapse later.
Wrapping the turban
Once the blank is dry, it's time to make it pretty and airtight. You'll wrap the area between the second and third wires with heavy cotton or nylon thread. This creates the "turban." It's not just for looks; it provides a handle for the reed and adds some structural integrity.
After wrapping, you'll coat the thread in glue or lacquer. This seals the bottom of the reed so air doesn't leak out of the sides. If your reed leaks air, you'll be fighting for every note, and nobody wants that.
The art of the scrape
Now we get to the part that separates the pros from the amateurs: the finishing. You've got a "blank" that looks like a reed but sounds like a dying duck (or doesn't make a sound at all).
First, you have to clip the tip. Use a tip cutter or a very steady hand with your knife. Once the tip is open, the reed should "crow" when you blow into it. A good crow usually has a mix of high and low frequencies. If it's just a high-pitched squeak, the reed is too thick.
Finding the balance
When you're scraping, you're trying to create a "profile." This means the back of the reed (near the wires) is thicker, and it tapers down to a very thin tip.
- The Spine: This is the center of the reed. Keep this a bit thicker to give the reed "heart" and stability.
- The Rails: These are the sides. Thinning these out can help with response.
- The Channels: The areas between the spine and the rails. This is where you do most of your fine-tuning.
Take off tiny amounts of cane at a time. You can always take more off, but you definitely can't put it back on. Test the reed constantly. Play some low notes to see if it speaks easily, then jump to the high register to see if it collapses.
Final tweaks and troubleshooting
Even after you think you're done, a reed will change over the first few days of playing. It "breaks in." You might find that a reed that felt perfect on Tuesday feels like a piece of plywood on Thursday.
If the reed is too "bright" or buzzy, you might need to take a little more off the back or the sides. If it's too "dark" or stuffy, thinning the tip slightly usually does the trick. It's a constant game of give and take.
Learning how to make bassoon reeds is honestly a lifelong journey. You'll make hundreds of "duds" before you consistently make "studs." But once you find that perfect scrap and the reed just sings, all those hours at the workbench feel totally worth it. Just keep your knives sharp, your cane soaked, and your patience high!
