Bassoon double reed

The bassoon double reed is the instrument's heart, handcrafted from two blades of Arundo donax that vibrate to produce its distinctive sound.

About this subject

The bassoon double reed is an essential and complex component responsible for producing the instrument's sound. Unlike the single reeds of clarinet or saxophone, the bassoon double reed consists of two blades of Arundo donax (giant cane) carefully cut, scraped, and tied onto a metal tube called a bocal. The crafting process is artisanal and requires great skill: the reed maker selects the cane, shapes the blades to millimetric thickness, and adjusts them to achieve the ideal sound response and resistance. Each reed is unique, and bassoonists often spend hours adjusting their own reeds to attain the desired timbre and ease of playing.

Historically, the double reed evolved alongside the bassoon. In the Baroque period, reeds were wider and more open, producing a softer sound. With the development of the modern bassoon (Heckel system, predominant since the 19th century), reeds became narrower and more controlled, allowing greater projection and dynamic flexibility. Today, different reed styles exist: the German style (more closed, with a long scrape) and the French style (more open, with a short scrape), which directly influence the instrument's sound and response.

Reed maintenance is crucial for the musician. Reeds are typically soaked in water for a few minutes before playing and must be stored in a ventilated case to prevent mold. They last from a few weeks to a few months, depending on usage and care. Many bassoonists learn to make their own reeds in workshops or from teachers, making this skill a fundamental part of the player's training. In addition to the bassoon, similar double reeds are used in the oboe, English horn, and contrafagotto, but with specific dimensions and characteristics for each instrument.

Frequently Asked Questions

Why is the bassoon double reed so important for the instrument's sound?

The double reed is the vibration source that generates sound. Its geometry, thickness, and adjustment determine the timbre quality, ease of response, and dynamics of the bassoon. A poorly made reed can make the instrument difficult to play or produce a poor sound.

What is the difference between a bassoon double reed and an oboe reed?

The bassoon reed is larger and wider than the oboe reed because the bassoon has a lower register. Additionally, the bassoon reed has a longer scrape and is tied onto a metal tube (bocal), while the oboe reed is usually attached to a wooden staple.

How does a bassoonist care for their reeds?

The bassoonist should soak the reed in water for 2 to 3 minutes before playing, avoiding wetting the bocal. After use, the reed should be dried and stored in a ventilated case. Reeds should be rotated periodically to prevent uneven wear and adjusted with razor blades or specific tools to correct the scrape.
