The clarinet was invented in Germany by Johann
Christoph Denner around the turn of the 18th century. Over time,
additional keys and airtight pads were added to improve tone and
playability. Today, the clarinet is used in both jazz, orchestra,
concert bands and many other ensembles.
The cylindrical bore is largely responsible for the
clarinet's distinctive sound, which varies between its three main
registers. It can play over four octaves depending on the ability of the
musician. The tone quality can vary greatly with the musician, the
music, the clarinet (material, manufacturer, etc.) and the strength of
the reed. The differences in instruments and geographical isolation of
players in different countries led to the development, from the last
part of the 18th century onwards, of several different schools of
clarinet playing. The most prominent of these schools were the
German/Viennese traditions and the French school, centered around the
clarinetists of the Conservatoire de Paris. Through the proliferation of
recorded music, examples of different styles of clarinet playing have
become available. The modern clarinetist has an eclectic palette of
"acceptable" tone qualities to choose from.
The clarinet is the most important woodwind in the
orchestra, and has a very wide range. It has 18 holes, six of which are
covered by fingers and the remainder by keys. The pitch of the tone is
determined by covering the holes. Clarinets used to all be made of wood
but now many are made of ebonite. All have single reeds. There are
thirteen different types of clarinets, but the most common in orchestras
are the B-flat for the keys with flats and the A for the keys with
sharps. Clarinets have a smooth, even sound, which makes them compatible
with most orchestral instruments. They can play many different moods,
and can play very loud or very soft. Because of this, in military bands
a clarinet plays the role of the violin. If an orchestra requires a
saxophone, and one is not available, a clarinet could play that role
also. The lower-sounding clarinets (like the alto, bass and contrabass)
have upturned metal bells, which cause them to resemble a saxophone in
appearance. The bass clarinet is comparable to the cello in pitch.
