The
horn is a
brass
instrument consisting of about of tubing wrapped into a coil
with a flared bell. A musician who plays the horn is called a
horn player (or less
frequently, a hornist).
Descended from the
natural horn, the
instrument is informally known as the
French horn,
but since 1971 the
International Horn Society has
recommended the
horn.
Horns have valves, operated with the left hand, to route the air
into extra tubing to change the pitch. Most horns have
lever-operated
rotary valves, but some
horns like the
Vienna horn use
piston valves (similar to
trumpet valves). A horn without valves is known as a
natural horn, changing pitch along the
natural
harmonics of the instrument
(similar to a
bugle), but with a
wide range of notes due to the long tubing.
Three valves control the flow of air in the
single horn,
which is tuned to F or less commonly, B . The more common
double horn has a fourth valve, usually operated by the
thumb, which routes the air to one set of tubing tuned to F or the
second set of tubing tuned to B . Triple horns with five valves are
also made, tuned in F, B , and a descant E or F.
General characteristics
The horn is the second highest sounding instrument group in the
brass family. Horns are mostly tuned in B or F, or a combination of
those. In some traditions, novice players use a single horn in F,
while others prefer the B horn. Compared to the other brass
instruments in the orchestra, it has a very different
mouthpiece, but has the widest usable
range - approximately four octaves, depending on the ability of the
player. To produce different notes on the horn, one must do many
things - the four most important are pressing the valves, holding
the appropriate amount of lip tension, blowing air into the
instrument, and placing the hand in the bell. More lip tension and
faster air produces higher notes. Less lip tension and slower air
produces lower notes. The right hand, usually cupped at a "three
o-clock" position in the bell, can lower the pitch, depending on
how far into the bell the player puts it, by as much as a
semitone in the instrument's midrange. The horn
plays in a higher portion of its
overtone
series compared to most brass instruments. Its conical bore (as
opposed to the cylindrical bore of the trumpet or trombone) is
largely responsible for its characteristic tone, often described as
"mellow".
Today, music for the horn is typically written in F (or sometimes,
notably in British bands, in E ), and sounds a perfect fifth lower
than written (or a major sixth lower for the E horn). The
limitations on the range of the instrument are primarily governed
by the available valve combinations for the first four octaves of
the overtone series and after that by the ability of the player to
control the pitch through their air supply and embouchure. The
typical written ranges for the horn start at either the F
immediately below the bass clef or the C an octave below middle
C.
The standard range starting from a low F is based on the
characteristics of the single horn in F. However, there is a great
deal of music written beyond this range on the assumption that
players are using a double horn in F/B . This is the standard
orchestral instrument and its valve combinations allow for the
production of every chromatic tone from two octaves on either side
of the horn's written middle-C (sounding F two octaves below the
bass clef to F at the top of the treble clef). Although the upper
range of the horn repertoire rarely exceeds high C (two octaves
above the horn's middle C, sounding F at the top of the treble
clef), skilled players can achieve yet higher pitches.
Also important to note is that many pieces from the Baroque to
Romantic periods are written in keys other than F. This practice
began in the early days of the horn before valves, when the
composer would indicate the key the horn should be in (horn in D,
horn in C, etc.) and the part would be notated as if it were in C.
For a player with a valveless horn that is a help, showing where in
the harmonic series a particular note is. A player with a modern
instrument must provide the final transposition to the correct
pitch. For example, a written C for horn in D must be transposed
down a minor third and played as an A on F horn.
History
Early horns were much simpler than modern horns, consisting of
brass tubes with a slightly flared opening (the bell) wound around
a few times. These early "hunting" horns were originally played on
a hunt, often while mounted, and the sound they produced was called
a recheat. Change of pitch was effected entirely by the lips (the
horn not being equipped with valves until the 19th century).
Without valves, only the notes within the
harmonic series are available. The
horn was used, among other reasons, to call hounds on a hunt and
created a sound most like a human voice, but carried much
farther.
In orchestral settings, the horn (or, more often, pairs of horns)
often invoked the idea of the hunt, or, beginning in the later
baroque, determined the character of the key being played or
represented nobility, royalty, or divinity.
Early horns were commonly pitched in B alto, A, A , G, F, E, E , D,
C, and B basso. Since the only notes available were those on the
harmonic series of one of those pitches, they had no ability to
play in different keys. The remedy for this limitation was the use
of
crooks, i.e. sections of tubing of
differing length that, when inserted, altered the length of the
instrument, and thus its pitch.
Orchestral horns are traditionally grouped into "high" horn and
"low" horn pairs. Players specialize to negotiate the unusually
wide range required of the instrument. Formerly, in certain
situations, composers would call for two pairs of horns in two
different keys; for example, a composer might call for two horns in
C and two in E for a piece in c minor, in order to gain harmonics
of the relative major unavailable on the C horns. Eventually, two
pairs of horns became the standard, and from this tradition of two
independent pairs, each with its own "high" and "low" horn, came
the modern convention of writing the 1st and 3rd parts above 2nd
and 4th.
In the mid-18th century, horn players began to insert the right
hand into the bell to change the length of the instrument,
adjusting the tuning up to the distance between two adjacent
harmonics depending on how much of the opening was covered. This
technique, known as
hand-stopping, is
generally credited to
Anton Joseph
Hampel around 1750, and was refined and carried to much of
Europe by the influential
Giovanni
Punto. This offered more possibilities for playing notes not on
the harmonic series. By the early classical period, the horn had
become an instrument capable of much melodic playing. A notable
example of this are the four Mozart Horn Concerti and Concert Rondo
(K. 412, 417, 477, 495, 371), wherein melodic chromatic tones are
used, owing to the growing prevalence of hand-stopping and other
newly-emerging techniques.
Around 1815 the use of pistons (later rotary valves) was
introduced, initially to overcome problems associated with changing
crooks during a performance. At first, however, valves were slowly
adopted in the mainstream because of unreliability, musical taste,
and players' distrust, among other reasons. Many traditional
conservatories and players refused to transition at first, claiming
that the valveless horn, or "
natural
horn", was a better instrument. Some musicians, specializing in
period instruments, still use a natural horn when playing in
original performance styles, seeking to recapture the sound and
tenor in which an older piece was written.
However, the use of valves opened up a great deal more flexibility
in playing in different keys; in effect, the horn became an
entirely different instrument, fully chromatic for the first time.
Although, valves were originally used primarily as a means to play
in different keys without crooks, not for harmonic playing. That is
reflected in compositions for horns, which only began to include
chromatic passages in the late 19th century. When valves were
invented, generally, the French made smaller horns with piston
valves and the Germans made larger horns with rotary valves. It is
the German horn that is erroneously referred to in the English
language (and more commonly in the United States and Canada) as the
French horn. There is not a clear consensus on the reason or
reasons for this nomenclature, and, as there are conflicting
proposals, more research is necessary.
Types of horns

A natural horn has no valves, but can
be tuned to a different key by inserting different tubing, as
during a rest period.
Natural horn
The
natural horn is the ancestor of the
modern horn. It is essentially descended from hunting horns, with
its pitch controlled by air speed, aperture (opening of the lips
through which the air passes) and the use of the right hand moving
in and out of the bell. Today it is played as a
period instrument. The
natural horn can only play from a single harmonic series at a time
because there is only one length of tubing available to the horn
player. The player has a choice of key through changing the length
of tubing with crooks.
Single horn
Single horns use a single set of tubes connected to the valves.
This allows for simplicity of use and a much lighter weight. They
are usually in the keys of F or B , although many F horns have
longer slides to tune them to E , and almost all B horns have a
valve to put them in the key of A. The problem with single horns is
the inevitable choice between accuracy or tone - while the F horn
has the "typical" horn sound, above third-space C accuracy is
concern for the majority of players because, by its nature, one
plays high in the horn's harmonic series where the overtones are
closer together. This led to the development of the B horn, which,
although easier to play accurately, has a less desirable sound in
the mid and especially the low register where it is not able to
play all of the notes. The solution has been the development of the
double horn which combines the two into one horn with a single lead
pipe and bell. Both main types of single horns are still used today
as student models because they are cheaper and lighter than double
horns. In addition, the single B horns are sometimes used in solo
and chamber performances and the single F survives orchestrally as
the
Vienna horn. Additionally, single F
alto and B alto descants are used in the performance of some
baroque horn concertos and F, B and F alto singles are occasionally
used by
jazz performers.
Dennis Brain's benchmark recordings of
the Mozart Horn Concerti were made on a single B instrument by
Gebr. Alexander, now on display at the Royal Academy of
Music
in London.
Double horn

Scheme of a double horn
(
view from underneath)
Despite the introduction of valves, the single F horn proved
difficult for use in the highest range, where the partials grew
closer and closer, making accuracy a great challenge. An early
solution was simply to use a horn of higher pitch—usually B . The
use of the F versus the B horn was a hotbed of debate between horn
players of the late nineteenth century, until the German horn maker
Ed. Kruspe
produced a prototype of the "double horn" in 1897.
The double horn also combines two instruments into a single frame:
the original horn in F, and a second, higher horn keyed in B . By
using a fourth valve (usually operated by the thumb), the horn
player can quickly switch from the deep, warm tones of the F horn
to the higher, brighter tones of the B horn. The two sets of tones
are commonly called "sides" of the horn. Using the fourth valve not
only changes the basic length (and thus the harmonic series and
pitch) of the instrument, it also causes the three main valves to
use proportionate slide lengths.
In the USA, the two most common styles ("wraps") of double horns
are named Kruspe and Knopf, after the first instrument makers who
developed and standardized them. The Kruspe wrap locates the B
change valve above the first valve, near the thumb. The Knopf wrap
has the change valve behind the third valve, near the pinky finger
(although the valve's trigger is still played with the thumb). In
effect, the air flows in a completely different direction on the
other model. Kruspe wrap horns tend to be larger in the bell throat
than the Knopf type. Typically, Kruspe models are constructed from
nickel silver or German Silver, while
Knopf type horns tend to be of yellow brass. Both models have their
own strengths and weaknesses, and while the choice of instrument is
very personal, an orchestral horn section is usually found to have
either one or the other, owing to the differences in tone color,
response, and projection of the two different styles.
In Europe the most popular horns are arguably those made by Gebr.
Alexander, of Mainz (particularly the Alexander 103), and those
made by
Paxman in London.
In Germany and the Benelux countries, the Alex. 103 is extremely
popular. These horns do not fit strictly into the Kruspe or Knopf
camps, but have features of both. Alexander prefers the traditional
medium bell size, which they have produced for many years, whereas
Paxman do offer their models in a range of bell throat sizes. In
the United States, the Conn 8D, a mass produced instrument based on
the Kruspe design, has been extremely popular in many areas (New
York, Los Angeles, Cleveland, Philadelphia). Since roughly the
early 1990s, however, for reasons ranging from changing tastes to a
general dislike of Conn's newer 8Ds, orchestras have been moving
away from the popular Conn 8D. Knopf model horns (by Geyer, Karl
Hill, Keith Berg, Steve Lewis, Dan Rauch, and Ricco-Kuhn) are used
in other areas (San Francisco, Chicago, Pittsburgh, Boston,
Houston).
Compensating double horn
The first design of double horn did not have a separate set of
slides pitched in F. Rather, the main key of the horn was B (the
preference of German horn players) and it could be played in F by
directing air through the B slides, an F extension, and another set
of tiny slides. This "compensated" for the longer length of the F
slides, producing a horn now called the "compensating double". It
was, and still is, widely used by European horn players because of
its light weight and ease of playing, especially in the high
register.
Triple horn
This relatively new design was created to afford the player even
more security in the high register. It employs not only the F and B
horns, but also a third, descant horn. This descant horn is usually
pitched an octave above the F horn, though it can be alternatively
pitched in E . It is activated through the use of a second thumb
valve. The triple horn was met with considerable resistance when it
first appeared. Horn players were reluctant to spend far more money
for a triple horn than they would for a double horn, and a feeling
that using a triple horn to help with the high register was
"cheating" was rampant amongst prominent horn players. Also, the
horns were much heavier than the average double horn. Players noted
that their arms became fatigued much faster. Moreover, the
combination of three different horns creates issues with sonority
because the piping which is shared among all three sides (that is,
the lead pipe and bell) are mathematically disproportional to two
or all three horn lengths. Horn makers have had to make concessions
to "even out" the sound between all three, often to the loss of
sound quality of each side or entire ranges of the instrument.
However, advances in horn production are gradually eliminating
these drawbacks, and the triple horn is gaining popularity. They
are rarely available in anything lower than professional quality.
Like double horns, triple horns can come in both full and
compensating wraps. Today, they are found being played in many
professional orchestras.
Vienna horn

Vienna horn
The
Vienna horn is a special horn used
primarily in Vienna
, Austria
.
Instead of using
rotary valves or
piston valves, it uses the
Pumpenvalve (or Vienna Valve), which is a
double-piston operating inside the valve slides, and usually
situated on the opposite side of the corpus from the player's left
hand, and operated by a long pushrod. Unlike the modern horn, which
has grown considerably larger internally (for a bigger, broader,
and louder tone), and considerably heavier (with the addition of
valves and tubing in the case of the double horn) the Vienna horn
very closely mimics the size and weight of the natural horn,
(although the valves do add some weight, they are lighter than
rotary valves) even using crooks in the front of the horn, between
the mouthpiece and the instrument. Although instead of the full
range of keys, Vienna horn players usually use an F crook for most
music, switching to an A or B crook for higher pitched music
(Beethoven 7th symphony, Bach, various Mozart and Haydn, etc).
Vienna horns are often used with funnel shaped mouthpieces similar
to those used on the natural horn, with very little (if any)
backbore and a very thin rim. The Viennese horn requires very
specialized technique and can be quite challenging to play, even
for accomplished players of modern horns.
Marching horn
The marching horn is quite similar to the mellophone in shape and
appearance, but is pitched in the key of B (the same as the B side
of a regular double horn). It is also available in F alto (one
octave above the F side of a regular double horn). The marching
horn is also normally played with a horn mouthpiece (unlike the
mellophone, which needs an adapter to fit the horn mouthpiece).
These instruments are primarily used in marching bands. However,
many college marching bands and drum corps use mellophones instead
which better balance the tone of the other brass instruments.
Mellophone
Sometimes, a derivative of the F
alto
horn, commonly used in brass bands and marching bands, called a
mellophone or mellophonium is used. It is shaped like a cornet,
with piston valves played with the right hand and a
forward-pointing bell. These horns are generally considered better
marching instruments than regular horns because their position is
more stable on the mouth, they project better, and they weigh less.
Though they are usually played with a trumpet like mouthpiece,
their range overlaps the common playing range of the horn. This
mouthpiece switch makes the mellophone louder, less mellow, and
more brassy and brilliant, making it more appropriate for marching
bands. It is a sound similar to that of the
bass trumpet. Often now with the use of
converters, traditional conical horn mouthpieces are used to
achieve the more mellow sound of a horn, in order to make the
marching band sound more like a symphonic band. There are two
instruments with the moniker "mellophone". The first, rarely seen
in the 21st century is an instrument shaped somewhat like a horn in
that it is wrapped in a circle. It has piston valves and is played
with the right hand on the valves. The second instrument is most
accurately called a "marching mellophone". It is keyed in E-flat
alto and is the instrument described when discussing modern
marching instruments.
As they are pitched in E-flat and their range overlaps that of the
horn, mellophones can be used in place of the horn in brass and
marching band settings. Sometimes, however, mellophones are
unpopular with horn players because the mouthpiece change can be
difficult and requires a different
embouchure. Mouthpiece adapters are available so
that a horn mouthpiece can fit into the mellophone lead pipe, but
this does not compensate for the many differences that a horn
player must adapt to. The bore is generally cylindrical as opposed
to the more conical horn; thus, the "feel" of the mellophone can be
foreign to a horn player. Another unfamiliar aspect of the
mellophone is that it is played with the right hand instead of the
left. Intonation can also be an issue when playing the
mellophone.
In orchestral concerts, regular concert horns are normally
preferred to mellophones because of their tone, which blends better
with woodwinds and strings, and their greater intonational
subtlety—since the player can adjust the tuning by hand. For these
reasons, mellophones are played more usually in marching bands and
brass band ensembles, occasionally in jazz bands, and almost never
in orchestral settings.
While horn players may be asked to play the mellophone, it is
unlikely that the instrument was ever intended to be used as a
substitute for the horn, mainly because of the fundamental
differences described. As an instrument it compromises between the
ability to sound like a horn, while being used like a trumpet or
fluglehorn; a tradeoff that sacrifices acoustic properties for
ergonomics.
Wagner tuba
The Wagner tuba is a rare brass instrument that is essentially a
horn modified to have a larger bell throat and a vertical bell.
Contrary to intuition, it is generally not considered part of the
tuba family. Invented for
Richard Wagner specifically for his work
Der Ring des Nibelungen, it
has since been written for by various other composers, including
Bruckner, Stravinsky and R. Strauss. It uses a horn mouthpiece and
is available as a single tuba in B or F, or, more recently, as a
double tuba similar to the double horn. Its common range is similar
to that of the
euphonium, but its possible
range is the same as that of the horn, extending from low F , below
the bass clef staff to high C above the treble staff when read in
F. These low pedals are substantially easier to play on the Wagner
tuba than on the horn.
Other modifications
The horn, although not large, is awkward in its shape and does not
lend itself well to transport, especially transport on commercial
airlines. To compensate, horn makers can make the bell detachable.
This allows for smaller and more manageable horn cases. The player
can attach the bell when performing. This also allows for different
bells to be used on the same horn, somewhat alleviating the need
for multiple horns for different styles.
Repertoire
Orchestral
The horn is most often used as an orchestral instrument, with its
singular tone being employed by composers to achieve specific
effects.
Leopold Mozart, for example,
used horns to signify the hunt, as in his
Jagdsinfonie (hunting symphony). Once the
technique of
hand-stopping had been
developed, allowing fully chromatic playing, composers began to
write seriously for the horn.
Telemann wrote much for the horn, and
it features prominently in the work of
Handel and in
Bach's
Brandenburg Concerto no.
1.
Gustav Mahler made great use
of the horn's uniquely haunting and distant sound in his
symphonies, notably the famous
Nachtmusik (serenade)
section of his
Symphony No.
7.
Many composers have written just one or a few notable works which
have become established as favorites in the horn repertoire; this
includes
Poulenc (
Elegie)
and
Saint-Saëns
(
Concertpiece for horn and orchestra, op. 94 and
Romance). Others, particularly
Mozart, whose friend
Joseph Leutgeb was a noted horn player, wrote
extensively for the instrument including
concerti and other solo works. Mozart's
A Musical Joke satirizes the
limitations of contemporary horn playing, including the risk of
selecting the wrong crook by mistake. By the end of the 18th
Century the horn was sufficiently established as a solo instrument
that the horn player Giovanni Punto became an international
celebrity, touring
Europe and inspiring works
by composers as significant as
Beethoven.
The development of the valve horn was exploited by romantic
composers such as
Richard Strauss,
Bruckner and Mahler. Strauss's
Till Eulenspiegel's
Merry Pranks contains one of the best known horn solos
from this period, relying on the chromatic facility of the valved
horn.
Horn music in Britain had something of a renaissance in the mid
20th Century when Dennis Brain inspired works such as
Britten's Serenade for Tenor, Horn
and Strings and other works from contemporary composers
such as
Michael Tippett, who
stretches horn ensemble playing to its technical limits in his
Sonata for Four Horns.
Peter
Maxwell Davies was commissioned by 50 amateur and professional
UK horn players to write a horn piece to commemorate the 50th
anniversary of Brain's death.
Much of the repertoire is scored as featured parts for the
orchestral players, especially the principal horn. It is common for
leading horn players to move from principal positions in the great
orchestras to distinguished solo careers, a path followed by Brain
and many since.
Due to the heroic quality of the sound produced by horns, they are
often used extensively in
film
music.
Chamber music
There is an abundance of chamber music repertoire for horn. It is a
standard member of the
wind quintet and
often appears in other configurations, such as Brahms' "
Horn Trio" for violin, horn and piano.
Also, the horn can be used by itself in a horn ensemble or "horn
choir." The horn choir is especially practical because the extended
range of the horn provides the composer or arranger with more
possibilities, registerally, sonically, contrapuntally, etc.
Orchestral horns
A classical orchestra usually contained two horns. Typically, the
1st horn played a high part and the 2nd horn played a low part.
Composers from
Beethoven
onwards commonly used four horns. Here, the 1st and 2nd horns
played as a pair (1st horn being high, 2nd horn being low), and the
3rd and 4th horns played as another pair (3rd horn being high, 4th
horn being low). In music written for the modern horn follows a
similar pattern with 1st and 3rd horns being high and 2nd and 4th
horns being low.
This setup of high-low-high-low has many reasons: Firstly, it makes
it easier to play a high part if you have someone on your left
playing a low part, but it makes it easier to play a low part if
you have your high player (from your pair) to your left. Secondly,
pairing makes it easier to write for horns, seeing as the 3rd and
4th horns can take over from the 1st & 2nd horns, or play a
contrasting part. Thirdly, when music was first written, it was for
the
natural horn, which meant that the
horns could only easily play certain notes. Because of this, the
1st and 2nd horns had to be in a different key from the 3rd and 4th
horns so that more of the notes can be played. For example, if the
piece is in C minor, the 1st and 2nd horns might be in C, the tonic
major key, which could get most of the notes, and the 3rd and 4th
horns might be in E , the relative major key, to fill in the
gaps.
Most horn sections today also have an assistant who doubles the 1st
horn part for selected passages joining in loud parts, playing
instead of the principal if there is a 1st horn solo approaching,
or alternating with the principal if the part is tiring to play.
Playing assistant is usually overlooked, but it is harder than it
seems, and takes experience to do it well. Often the assistant is
asked to play a passage after resting a long time. Also, he or she
may be asked to enter in the middle of a passage, exactly matching
the sound, articulation, and overall interpretation of the
principal. The assistant is occasionally referred to as a
"bumper".
Some pieces (like
Rachmaninov's
Isle of the
Dead, Britten's
Sinfonia da Requiem,
Holst's The
Planets and Richard Strauss'
Don Quixote) have called for
6 horns, or as many as 20 horns, as found in Eine Alpinesinfonie,
by Richard Strauss . Here the pairing remains the same, with the
odd horns being high parts and the even horns being low
parts.
In jazz
The horn has been rarely used in
jazz music.
Notable exponents, however, include composer/arranger
Gil Evans who included the horn as an ensemble
instrument from the 1940s, first in
Claude Thornhill's groups, and later with
the pioneering
cool jazz nontet led by
trumpeter
Miles Davis. Notable
improvising horn soloists in jazz include
Julius Watkins,
Willie
Ruff and
Tom Varner.
