Player's notes

  • The most common clarinet: written C sounds B♭ a whole step lower.
  • Overblows at the twelfth (octave + fifth), not the octave — the reason its fingerings repeat a twelfth apart.
  • Four registers: chalumeau (E3–F#4), throat (G4–B♭4), clarion (B4–C6) and altissimo (C#6 up).
  • A cylindrical bore closed at the reed end gives the characteristic odd-harmonic, hollow low register.

About the B♭ Clarinet

The clarinet is a single-reed musical instrument in the woodwind family, with a nearly cylindrical bore and a flared bell.

Clarinets comprise a family of instruments of differing sizes and pitches. The clarinet family is the largest woodwind family, ranging from the BB♭ contrabass to the A♭ piccolo. The B♭ soprano clarinet is the most common type, and is the instrument usually indicated by the word "clarinet".

German instrument maker Johann Christoph Denner is generally credited with inventing the clarinet sometime around 1700 by adding a register key to the chalumeau, an earlier single-reed instrument. Over time, additional keywork and airtight pads were added to improve the tone and playability. Today the clarinet is a standard fixture of the orchestra and concert band and is used in classical music, military bands, klezmer, jazz, and other styles.
