Clarinet reeds and their associated frustrations is a hot conversation topic for clarinettists worldwide – and one that they can get very exercised about. But why all the fuss? Here is our ultimate guide to the clarinet reed: what it does, why it’s so important and even how you might begin to go about making one.

What does a clarinet reed do?

A clarinet reed is a thin strip of material that vibrates when a musician blows air between it and the mouthpiece, producing a certain tone.

What is a clarinet reed made of?

The clarinet reed is made of Arundo donax, a kind of cane – quite similar in appearance to bamboo – with fibrous, woody stalks. It is typically found in the Mediterranean, as well as parts of America.

How is a clarinet reed different from that of other woodwind instruments?

Whereas the oboe and bassoon use a double reed comprising two pieces of wood that vibrate against each other, the clarinet uses only one reed, which vibrates against the mouthpiece.

Do clarinettists typically make their own reeds?

Unlike oboists, who, for best results, do make their own reeds, clarinettists tend to buy them pre-manufactured. But even though commercial reeds are all cut by machines in exactly the same way with extreme precision, from a full box of reeds, only a few will be usable, and from those only two or three will produce a passable sound. That’s because no two pieces of cane are exactly alike, and will respond differently even when formed into exactly the same shape.

So many of the more advanced clarinettists do add finishing touches to their reeds, modifying them with sandpaper or a knife to achieve the desired response and sound.

How are clarinet reeds made?

After the cane is cut it is placed in direct sunlight for about a month to dry. Once dry, the cane is taken to a factory’s cutting department, where it is cut into tubes graded by diameter and wall density. The tubes are cut into splits and made into reed blanks, which are then tapered and profiled into reeds using automated blades.

As for the process of hand-making a clarinet reed: that’s where things get rather nebulous,  given that specific approaches vary between individuals. Some clarinettists swear by curing (soaking and drying) the cane before turning them into reeds; others don’t bother. Generally, though, all approaches involve cutting the cane into pieces or ‘blanks’, sanding them down, and sculpting them into shape (see how we managed to gloss over the details?). Here’s one of the less esoteric how-to videos we could find.
