The Denner Family Workshop in Nuremberg
Johann Christoph Denner came from a family of instrument makers and horn tuners. His father, Heinrich Denner, made hunting horns and game whistles before moving the family to Nuremberg in 1666, then one of the centers of European instrument making.
From his father, Johann learned the craft of instrument building while also becoming an accomplished musician. Around 1666 he went into business for himself, and was granted rights for the manufacture of French musical instruments, chiefly oboes and recorders. His woodwinds, prized for their tuning, were regarded throughout Europe as among the finest available.
How Johann Christoph Denner Invented the Clarinet
How a limited folk instrument became the clarinet, and why the change amounted to a new invention rather than a modification.
Denner based his new instrument on an earlier single-reed woodwind called the chalumeau, similar in appearance to a recorder. But the changes he made were significant enough that historians do not consider the clarinet a simple evolution of the chalumeau; it is treated as a distinct invention.
The chalumeau's range was limited to about one and a half octaves, because unlike a flute, oboe, or bassoon, it would not "overblow" cleanly to the octave. Denner determined that the instrument instead overblows to a twelfth, and added a speaker key, a small hole near the mouthpiece, to make that upper register easier to reach. This addition, now called the clarion register, is the acoustic innovation that defines the clarinet.
Working with his son Jacob, Denner added finger keys to a chalumeau that, until then, looked much like a single-reed recorder.
At least sixty-eight surviving instruments bear the Denner name, but scholars believe most were made in the workshop of his son, Jacob Denner, after Johann Christoph's death. Apart from one disputed instrument, no clarinet built by Johann Christoph himself is known to survive; only chalumeaux carrying his mark remain.
When Did Johann Christoph Denner Invent the Clarinet?
The accepted date has shifted as historians have found earlier, more reliable sources.
The Graf (Duke) of Gronsfeld in Nuremberg orders two clarinets from Jacob Denner for his musicians, the earliest documented purchase of the instrument.
Johann Christoph Denner develops the clarinet from the chalumeau in his Nuremberg workshop, adding the speaker key that defines the instrument's upper register.
Scholar Thurston Dart publishes a music book for the "mock trumpet," a name some historians associate with the earliest clarinets; three similar volumes follow over the next decade.
The Nuremberg Town Band (Ratsmusik) purchases four boxwood clarinets, a transaction some historians credit with giving the instrument its name.
J.G. Doppelmayr, a contemporary of Denner, writes in his Report on the Mathematicians and Artisans of Nuremberg that Denner developed the clarinet a little after 1700, the earliest known written account.
A third key, enabling a low E, is added to the clarinet design; a fourth and fifth key are added later by Barthold Fritz.
C.G. Murr publishes an account dating the clarinet's invention to 1690. For nearly two centuries this was the accepted date, until Doppelmayr's earlier 1730 report was reexamined.
Because Doppelmayr's account was written decades closer to Denner's lifetime than Murr's, most historians today place the clarinet's invention at approximately 1700 to 1704, rather than the traditionally cited 1690.
How the Clarinet Works: The Chalumeau and the Register Key
The chalumeau, widely used across Europe but only occasionally in orchestras, resembled a recorder: seven finger holes, a thumb hole, and two keys for its highest notes. Its range, about one and a half octaves, limited its musical use.
Denner's addition of the speaker key let players reach a clear upper register by overblowing to a twelfth rather than an octave, the acoustic principle that still defines the clarinet today. Acoustically, the instrument behaves as a closed cylindrical tube. Early clarinets were built from boxwood, plum, ebony, ivory, or pear, with a flared bell and a single cane reed tied to the top of the mouthpiece.
Denner's original two-key design was expanded by later makers: a third key for a low E arrived around 1740, with a fourth and fifth key added afterward by the German maker Barthold Fritz.
Frequently Asked Questions About Johann Christoph Denner and the Clarinet
Short, direct answers to the questions most often asked about Johann Christoph Denner and the clarinet's invention.
Who invented the clarinet?
Johann Christoph Denner, a German instrument maker working in Nuremberg, is credited with inventing the clarinet by modifying an earlier single-reed instrument called the chalumeau.
When was the clarinet invented?
Historians once dated it to around 1690, based on an account written in 1778. An earlier, more contemporary 1730 report by J.G. Doppelmayr now places the invention closer to 1700 to 1704.
What instrument did the clarinet evolve from?
The chalumeau, a limited single-reed woodwind. Denner's speaker key let it overblow cleanly to a twelfth, extending its range and creating the tone that defines the clarinet.
Do any of Johann Christoph Denner's original clarinets survive?
No, aside from one disputed instrument. About sixty-eight surviving woodwinds bear the Denner name, but most are attributed to the later workshop of his son, Jacob Denner.
Where was Johann Christoph Denner born and where did he die?
He was born August 13, 1655, in Leipzig, Germany, and died April 20, 1707, in Nuremberg, where he had lived and worked since 1666.
