Clarinet keys closeup

The mechanical details of clarinet keys reveal the precision required for every musical note.

About this subject

The keys of a clarinet are the heart of its mechanism, allowing the musician to quickly open and close tone holes to produce different pitches. This key system evolved over centuries, with major contributions from makers like Buffet Crampon and Selmer. The most common model, the Boehm system (adapted for clarinet by Hyacinthe Klosé in 1839), typically uses 17 to 18 keys and six rings, offering comfortable fingering and good intonation. Materials such as nickel silver, silver, and gold are used for the keys, each affecting weight, durability, and tactile response. Stainless steel or brass springs ensure rapid return. For professional instruments, keys may be hand-engraved and individually adjusted. The Oehler system, mainly used in Germany and Austria, features more keys and rings, favoring a dense sound and dynamic flexibility. Regular maintenance, including cleaning and oiling, is essential to avoid noise and ensure smooth action.
