The Complete Handbook of Clarinet Reeds

Chapter 1: Understanding Clarinet Reeds

Before you play a single note, the reed has likely already decided a significant part of the outcome. It is the most sensitive, variable, and perishable component of the entire clarinet. While the instrument itself is a marvel of mechanical precision—its keys, pads, and bore crafted to exacting tolerances—the reed is a piece of living plant material, Arundo donax, that you are asking to vibrate at a controlled frequency for hours on end. Understanding what this material is, how the reed functions structurally, and why it produces the inconsistencies that plague every clarinetist is the first step toward mastering the instrument rather than merely wrestling with it.

A Piece of Cane, Not Plastic

At its most basic level, a clarinet reed is a thin, tapered sliver of cane. This cane, Arundo donax, is a giant perennial grass that thrives in specific Mediterranean and subtropical climates. The French province of Var, parts of southern Spain, and regions of Argentina have historically been the most prized sources. The reed you play began its life roughly three years before it reached your hands. The poles must be allowed to mature for two to three years, then are harvested, dried naturally, and stored for up to one another year before being split and milled. This long growing cycle, heavily influenced by rainfall and soil nutrients in the field, is a primary reason for the inconsistency you find in a freshly opened box. No two pieces of cane are identical
