The trombone is a musical instrument in the brass family. Like all brass instruments, sound is produced when the player’s vibrating lips (embouchure) cause the air column inside the instrument to vibrate. The trombone is usually characterised by the slide with which the player varies the length of the tube to change pitches. There are three types of trombones, bass, valve, and the valve trombone (uses three valves like those on a trumpet).

The word trombone derives from Italian tromba (trumpet) and -one (a suffix meaning "large"), so the name literally means "large trumpet". Trombones and trumpets share the important characteristic of having predominantly cylindrical bores. Trombone music, along with music for euphonium and tuba, is typically written in concert pitch while trumpet music is transposed to B, although exceptions do occur, the most notably being in brass band music. Most trombones are pitched in B, an octave below the trumpet and an octave above the tuba.

A person who plays the trombone is called a trombonist or trombone player.

The trombone consists of a roughly cylindrical tube bent into an elongated "S" shape. Rather than being truly cylindrical, the tube is a complex series of tapers with the smallest at the mouthpiece receiver and the largest just before the bell flare. The design of these tapers affects the intonation of the instrument. As with other brass instruments, sound is produced by blowing air through pursed lips producing a vibration that creates a standing wave in the instrument.

The detachable cup-shaped mouthpiece is similar to that of the baritone horn and closely related to that of the trumpet. It has the venturi: a small constriction of the air column that adds resistance greatly affecting the tone of the instrument, and is inserted into the mouthpiece receiver in the slide section. The slide section consists of a leadpipe, the inner and outer slide tubes, and the bracing, or stays. Modern stays are soldered, while sackbuts (medieval precursors to trombones) were made with loose, unsoldered stays (this remained the pattern for German trombones until the mid-20th century).

The 'slide', the most visible feature of the trombone, (cf. valve trombone) allows the player to extend the length of the air column, lowering the pitch. In order to prevent friction from slowing the action of the slide, additional sleeves were developed during the Renaissance and these stockings were soldered onto the ends of the inner slide tubes. Nowadays, the stockings are incorporated into the manufacturing process of the inner slide tubes and represent a fractional widening of the tube to accommodate the necessary method of alleviating friction. This part of the slide must be lubricated frequently. Additional tubing connects the slide to the bell of the instrument through a neckpipe, and bell or back bow (U-bend). The joint connecting the slide and bell sections is furnished with a ferrule to secure the connection of the two parts of the instrument, though older models from the early 20th century and before were usually equipped with friction joints and no ancillary mechanism to tighten the joint.

The adjustment of intonation is most often accomplished with a tuning slide that is a short slide between the neckpipe and the bell incorporating the bell bow (U-bend); this device was designed by the French maker François Riedlocker during the early nineteenth century and applied to French and British designs and later in the century to German and American models, though German trombones were built without tuning slides well into the 20th century. However, trombonists, unlike other instrumentalists, are not subject to the intonation issues resulting from valved or keyed instruments, since they can adjust intonation "on the fly" by subtly altering slide positions when necessary. For example, second position "A" is not in exactly the same place on the slide as second position "E." Many types of trombone also include one or more rotary valves used to increase the length of the instrument (and therefore lower its pitch) by directing the air flow through additional tubing.

Like the trumpet, the trombone is considered a cylindrical bore instrument since it has extensive sections of tubing, principally in the slide section, that are of continuous diameter. This contrasts with conical bore instruments like the cornet, euphonium, and tuba, whose only cylindrical tubing is in the valve section. Tenor trombones typically have a bore of 0.450" (small bore) to 0.547" (large or orchestral bore) after the leadpipe and through the slide. Some small bore jazz trombones, though, have two different diameters of tubing in the slide section to simulate a conical bore. Without this innovation, the trombone would sound extremely sharp and piercing. The bore expands through the backbore to the bell which is typically between 7" and 8½". A number of common variations on trombone construction are noted below.

History Edit

Renaissance and Baroque periods Edit

Main article: Sackbut

Until the early 18th century, the trombone was called the sackbut in England, although other countries used the same name throughout the instrument's history, viz. Italian trombone and German Posaune. The sackbut was built in slightly smaller dimensions than modern trombones, and had a bell that was more conical and less flared.

The instrument was used extensively across Europe from its appearance in the 15th century to a fading out in most places across the mid-late 17th century. It was used in outdoor events, in concert and in liturgical settings. The groups varied from alta capella, wind ensembles, with voices, and in the first 'orchestra'-type ensembles in religious settings such as St. Mark's Venice in the early 17th century. Famous composers writing for the trombone in this period include Giovanni Gabrieli and his uncle Andrea Gabrieli, Claudio Monteverdi and Heinrich Schütz. There are also some solo pieces written specifically for trombone in the early 17th century.

During the later Baroque period, Johann Sebastian Bach and George Frideric Handel used the trombone on few occasions; Bach used it in combination with the cornett to evoke the stile antico in some of his many cantatas and Handel used it in the Dead March from Saul, Samson, and Israel in Egypt, all of which were examples of a new oratorio style, popular during the early 18th century.

Classical period Edit

The use of the trombone in this period was mostly limited to Austria.

The repertoire of trombone solo and chamber literature has its beginnings in Austria in the Classical Era where composers such as Leopold Mozart, Georg Christoph Wagenseil, Johann Albrechtsberger and Johann Ernst Eberlin were featuring the instrument, often in partnership with a voice. Joseph Haydn and Wolfgang Amadeus Mozart used the trombones in a number of their sacred works, including two extended duets with voice from Mozart, the best known being in the Tuba Mirum of his Requiem. The inspiration for many of these works was no doubt the virtuosic playing of Thomas Gschladt who worked in the court orchestra at Salzburg, although when his playing faded, so did the general composing output for the instrument. The trombone retained its traditional associations with the opera house and the Church during the 18th century and was usually employed in the usual alto/tenor/bass trio to support the lower voices of the chorus, though Viennese court orchestra Kapellmeister Johann Joseph Fux rejected an application from a bass trombonist in 1726 and restricted the use of trombones to alto and tenor only, which remained the case almost until the turn of the 19th century in Vienna, after which time a second tenor trombone was added when necessary. The construction of the trombone changed relatively little between the Baroque period and Classical period with the most obvious feature being the slightly more flared bell than was previously the custom.

The first use of the trombone in a symphony was in 1807 in the Symphony in E♭ by the Swedish composer Joachim Nicolas Eggert 1, although the composer usually credited with its introduction into the symphony orchestra was Ludwig van Beethoven, who used it in the last movement of his Symphony No. 5 in C minor (1808). Beethoven also used trombones in his Symphony No. 6 in F major ("Pastoral") and Symphony No. 9 ("Choral").

Romantic period Edit

Leipzig became a centre of trombone pedagogy; the trombone began to be taught at the new Musikhochschule founded by Felix Mendelssohn Bartholdy. Mendelssohn's bass trombonist, Karl Traugott Queisser, was the first in a long line of distinguished professors of trombone at the academy in Leipzig and several composers penned works for him, including Ferdinand David (Mendelssohn's concertmaster), Ernst Sachse and Friedrich August Belcke, whose solo works all remain popular today in Germany. Queisser almost single-handedly helped to re-establish the reputation of the trombone in Germany and began a tradition in trombone-playing that is still practised there today. He championed and popularised Christian Friedrich Sattler's new tenorbass trombone during the 1840s, leading to its widespread use in orchestras throughout Germany and Austria. Sattler's influence on trombone design is not to be underestimated; he introduced a significant widening of the bore (the most important since the Renaissance), the innovations of Schlangenverzierungen (snake decorations), the bell garland and the wide bell flare, all of which are features that are still to be found on German-made trombones today and were widely copied during the 19th century.

Many composers were directly influenced by Beethoven's use of trombones, and the 19th century saw the trombones become fully integrated in the orchestra, particularly by the 1840s, as composers such as Franz Schubert, Franz Berwald, Johannes Brahms, Robert Schumann, Felix Mendelssohn Bartholdy, Richard Wagner, Hector Berlioz, Gioacchino Rossini, Giuseppe Verdi, Giacomo Puccini, Franz Liszt, Richard Strauss, Anton Bruckner, Gustav Mahler, Piotr Ilyich Tchaikovsky, Nikolai Rimsky-Korsakov, Alexander Borodin, Bedřich Smetana, Antonín Dvořák, Charles Gounod, César Franck, Claude Debussy, Camille Saint-Saëns and many others included trombones in their operas, symphonies and other orchestral compositions.

The 19th century also saw the erosion of the traditional alto/tenor/bass trombone trio in the orchestra. While the alto/tenor/bass trombone trio had been paired with one or two cornetts during the Renaissance and early Baroque periods, the disappearance of the cornett as a partner and eventual replacement by oboe and clarinet did not fundamentally alter the raison d'être for the trombones, which was to support the alto, tenor and bass voices of the chorus (typically in an ecclesiastical setting), whose harmonic moving lines were more difficult to pick out than the melodic soprano line. The introduction of the trombones into the orchestra, however, allied them more closely with the trumpets and it did not take long for the alto and bass trombones to be replaced by tenor trombones, although the Germans and Austrians held on to the alto trombone and F or E bass trombone somewhat longer than the French, who came to prefer a section of three tenor trombones until after the Second World War.

By the time the trombone gained a regular footing in the orchestra and opera, players of the instrument were no longer usually employed by a cathedral or court orchestra and were therefore expected to provide their own instrument. Military musicians were provided with instruments by the army and instruments like the long F or E bass trombone remained in use there until about the time of the First World War, but the orchestral musician understandably adopted the instrument with the widest range which could be most easily applied to play any of the three trombone parts usually scored in any given work - the tenor trombone. The appearance of the valve trombone during the mid-19th century did little to alter the make-up of the trombone section in the orchestra and though it remained popular almost entirely to the exclusion of the slide instrument in countries such as Italy and Bohemia, the valve trombone was ousted from orchestras in Germany and France. The valve trombone continued to enjoy an extended period of popularity in Italy and Bohemia and composers such as Giuseppe Verdi, Giacomo Puccini, Bedřich Smetana and Antonín Dvořák scored for a section of valve trombones.

Especially with the ophicleide or later the tuba subjoined to the trombone trio during the 19th century, parts scored for the bass trombone rarely descended as low as the parts scored before the addition of either of these new low brass instruments; only in the early 20th century did it regain a degree of independence. Experiments with different constitutions of the trombone section during the 19th and early 20th centuries, including Richard Wagner's addition of a contrabass trombone in Der Ring des Nibelungen and Gustav Mahler's and Richard Strauss' occasional augmentation by adding a second bass trombone to the usual trio of two tenor trombones and one bass trombone, have not had any lasting effect; the majority of orchestral works are still scored for the usual mid- to late-19th-century low brass section of two tenor trombones, one bass trombone and one tuba.

Twentieth century Edit

In the 20th Century the trombone maintained its important place in the orchestra with prominent parts in works by Richard Strauss, Gustav Mahler, Arnold Schoenberg, Alban Berg, Maurice Ravel, Darius Milhaud, Olivier Messiaen, Igor Stravinsky, Dmitri Shostakovich, Sergei Rachmaninov, Sergei Prokofiev, Ottorino Respighi, Edward Elgar, Gustav Holst, Ralph Vaughan Williams, Benjamin Britten, William Walton, Jean Sibelius, Carl Nielsen, Leoš Janáček, George Gershwin, Aaron Copland, Leonard Bernstein and Béla Bartók.

In the second half of the century, new composers began giving back to the trombone a level of importance in solo and chamber music. Pieces such as Edgard Varèse's Octandre, Paul Hindemith's Sonata and Luciano Berio's Sequenza V led the way for lesser-known composers to build a wider repertoire. Popular choices for recital music today include Stjepan Sulek's Vox Gabrieli, Jacques Casterède's Sonatine and Jean Michel Defaye's Deux Danses. Some well known trombone concertos from this period include works by Derek Bourgeois, Lars-Erik Larsson, Launy Grøndahl, Jan Sandström, Christopher Rouse and Henri Tomasi.

Numerous changes in construction have occurred during the 20th century, including the use of different materials, increases in mouthpiece, bore and bell dimensions, new valve types and different mute types.

Today, the trombone can usually be found in wind ensembles/concert bands, symphony orchestras, marching bands, military bands, brass bands, brass choirs, big bands, etc. It can be part of smaller groups as well, such as brass quintets, quartets, or trios, or trombone trios, quartets, or choirs (though the size of a trombone choir can vary greatly from five or six to twenty or more members). Trombones are also common in swing, jazz, merengue, salsa (prominent examples: Jimmy Bosch and Willie Colón), rock (Bill Reichenbach and James Pankow serving as two prominent examples), R&B, and ska (prominent example: Don Drummond).

Types Edit

Main article: Types of trombones

The most frequently encountered trombones today are the tenor and bass, though as with other Renaissance instruments such as the recorder, the trombone has been built in every size from piccolo to contrabass.

Trombones, while usually a slide instrument, are also made as valved instruments following the same convention as other tenor horns with 3 valves pitched to lower the partial played by 1 step (first valve), 1/2 step (second valve), or 1-1/2 steps (third valve) - or combinations thereof.

Slide trombones are freqently augmented with one or two rotary valves operated by left hand thumb trigger. The more typical single rotary valve is known commonly as an "F attachment" as it lowers a concert Bb (the fundamental of the instrument) to the pitch F concert. This essentially makes the trombone an F instrument rather than Bb. A second trigger is occasionally added to bass trobones to augment the range downward.

Technique Edit

File:Trombone slide position pedal tones.png

The pedal tone on B is frequently seen in commercial scoring but much less often in symphonic music while notes below that are called for only rarely as they, "become increasingly difficult to produce and insecure in quality" with A or G being the bottom limit for most trombonists.[1]

File:Trombone first position harmonic series.png

As with all brass instruments, progressive tightening of the lips and increased air pressure allow the player to move to a different partial in the harmonic series. In the first or closed position on a B trombone, the notes in the harmonic series begin with B2 (one octave higher than the pedal B1), F3 (a perfect fifth higher than the previous partial), B3 (a perfect fourth higher), D4 (a major third higher), F4 (a minor third higher), A4 (a minor third higher than the previous partial; this tone (the "seventh partial (sixth overtone)") is always 31 cents, about one sixth of a tone, flat of the twelve-tone equal temperament minor seventh, "however it can be brought into tune by an adjustment of the slide,"[1] it may be avoided and played in an alternate position, though it has been the practice in Germany and Austria to play the note in position, see harmonic seventh and just intonation), B4 (a major second higher), C5 (a major second higher), D5 (a major second higher), E♭ (a minor second higher, but almost exactly a quarter tone higher than it would be in twelve-tone equal temperament), F5 (a major second higher). Very skilled players with a highly developed facial musculature can go even higher than this, to G5, A5, B5 and beyond.

File:Trombone F slide position pedal tones.png

In the lower range, significant movement of the slide is required between positions, which becomes more exaggerated on lower pitched trombones, but for higher notes the player need only use the first four positions of the slide since the partials are closer together, allowing higher notes to be played in alternate positions. As an example, F4 (at the bottom of the treble clef) may be played in first, fourth or sixth position on a B trombone. The note E1 (or the lowest E on a standard 88-key piano keyboard) is the lowest attainable note on a 9' B tenor trombone, requiring a full 2.24 m of tubing. On trombones without an F attachment, there is a gap between B1 (the fundamental in first position) and E2 (the first harmonic in seventh position). Skilled players can produce so-called "falset" notes between these, but the sound is relatively weak and not usually used in performance.

File:Trombone seventh position harmonic series.png


The trombone is one of the few wind instruments that can produce a true glissando, by moving the slide without interrupting the airflow. During a trombone glissando the slide direction must not change or the sound will break, every pitch in a glissando must have the same harmonic number, and a tritone is the largest interval that can be performed as a glissando.[2]

File:Trombone false glissando Berg Wozzeck.png

'Harmonic', 'inverted', 'broken' or 'false' glissandos are those which cross one or more harmonic series, requiring a simulated or faked glissando effect.[3]


Trills, though effortless with valves, are difficult on the slide trombone and are easiest between a second or third found on the same or between adjacent harmonic series and most convincing above the first octave and a half of the tenor's range.[4]

Notation Edit

Unlike most other brass instruments in an orchestral setting, the trombone is not usually a transposing instrument. Prior to the invention of valve systems, most brass instruments were limited to playing one overtone series at a time; altering the pitch of the instrument required manually replacing a section of tubing (called a "crook") or picking up an instrument of different length. Their parts were transposed according to which crook or length-of-instrument they used at any given time, so that a particular note on the staff always corresponded to a particular partial on the instrument. Trombones, on the other hand, have used slides since their inception. As such, they have always been fully chromatic, so no such tradition took hold, and trombone parts have always been notated at concert pitch (with one exception, discussed below). Also, it was quite common for trombones to double choir parts; reading in concert pitch meant there was no need for dedicated trombone parts.

Trombone parts are typically notated in bass clef, though sometimes also written in tenor clef or alto clef. The use of alto clef is usually confined to orchestral first trombone parts intended for the alto trombone, with the second (tenor) trombone part written in tenor clef and the third (bass) part in bass clef. As the alto trombone declined in popularity during the 19th century, this practice was gradually abandoned and first trombone parts came to be notated in the tenor or bass clef. Some Russian and Eastern European composers wrote first and second tenor trombone parts on one alto clef staff (the German Robert Schumann was the first to do this). Examples of this practice are evident in scores by Igor Stravinsky, Sergei Prokofiev, Dmitri Shostakovich. Trombone parts may contain both bass and tenor clef or bass and alto clef sections.

An accomplished performer today is expected to be proficient in reading parts notated in bass clef, tenor clef, alto clef, and (more rarely) treble clef in C, with the British brass band performer expected to handle treble clef in B♭ as well.

Brass bands Edit

In brass band music, the tenor trombone is treated as a transposing instrument in B♭ and reads the treble clef (while the bass trombone uses the bass clef in concert pitch, as in orchestral music). This puts the notes in exactly the same staff position as they would be if the music were written in a (non-transposing) tenor clef, although the key signature and some accidentals must be adjusted. This is no mere coincidence, for brass bands used to employ a section of alto, tenor and bass trombones in the early to mid-19th century, later replacing the alto with a tenor trombone, all the while notated in the corresponding clefs. Eventually a decision was taken in the early 20th century to replace the tenor clef with the transposing B treble clef in order to aid new starters to integrate more quickly and effectively into the brass band, though the bass trombone, then in G, remained (and is still) notated in concert pitch bass clef. (Company bands used B and E treble clef notation for many instruments in the band to allow players to more easily switch instruments when personnel changed.)

Mutes Edit

See also Brass instrument mutes

A variety of mutes can be used with the trombone to alter its timbre. Many are held in place with the use of cork grips, including the straight, cup, harmon and pixie mutes. Some fit over the bell, like the bucket mute. In addition to this, mutes can be held in front of the bell and moved to cover more or less area for a wah-wah effect. Mutes used in this way include the "hat" (a metal mute shaped like a bowler) and plunger (which looks like, and often is, the rubber suction cup from a sink or toilet plunger), a sound featured as the voices of adults in the Peanuts cartoons.

Variations in construction Edit

Bells Edit

Trombone bells (and sometimes slides) may be constructed of different brass mixtures. Some believe that materials affect tone quality and timbre. The most common material is yellow brass (70% copper, 30% zinc), but other materials include rose brass (85% copper, 15% zinc) and red brass (90% copper, 10% zinc). Some manufacturers offer interchangeable bells. Tenor trombone bells are usually between 7 and 9 inches in diameter, the most common being sizes from 7½ to 8½ inches. The smallest sizes are found in small jazz trombones and older narrow-bore instruments, while the larger sizes are common in orchestral models. Bass trombone bells can be as large as 10½" or more, though usually either 9½ in or 10 in diameter. The bell may be constructed out of two separate brass sheets or out of one single piece of metal and hammered on a mandrel until the part is shaped correctly. The edge of the bell may be finished with or without a piece of bell wire to secure it, which also affects the tone quality; most bells are built with bell wire. Occasionally, trombone bells are made from solid sterling silver.

Valve attachments Edit

Valves Edit


Some trombones have valves instead of a slide (see valve trombone). These may be rotary valves, piston valves, or disc valves. Disc valves are modern versions of a valve invented in the 1820s which was discarded in favour of the rotary and the Périnet (piston) valve.

Tubing Edit

More often than not, tenor trombones with an F attachment, or trigger, have a larger bore through the attachment than through the 'straight' section (the portion of the trombone through which the air flows when the attachment is not engaged). Typically, for orchestral instruments, the slide bore is 0.547" and the attachment tubing bore is 0.562". A wide variety of valve attachments and combinations are available. Valve attachment tubing usually incorporates a small tuning slide so that the attachment tubing is able to be tuned separately from the rest of the instrument. Most B♭/F tenor and bass trombones include a tuning slide long enough to lower the pitch to E with the valve tubing engaged, enabling the production of B2. Whereas older instruments fitted with valve attachments usually had the tubing coiled rather tightly in the bell section (closed wrap or traditional wrap), modern instruments usually have the tubing kept as free as possible of tight bends in the tubing (open wrap), resulting in a freer response with the valve attachment tubing engaged.

Tuning Edit

Some trombones are tuned through a mechanism in the slide section rather than via a separate tuning slide in the bell section. This method preserves a smoother expansion from the start of the bell section to the bell flare. The tuning slide in the bell section requires two portions of cylindrical tubing in an otherwise conical part of the instrument, which affects the tone quality.

Slides Edit

Common and popular bore sizes for trombone slides are 0.500", 0.508", 0.525" and 0.547" for tenor trombones, and 0.562" for bass trombones. The slide may also be built with a dual bore configuration, in which the bore of the second leg of the slide is slightly larger than the bore of the first leg, producing a step-wise conical effect. The most common dual bore combinations are 0.481"-0.491", 0.500"-0.508", 0.508"-0.525", 0.525"-0.547", 0.547"-0.562" for tenor trombones, and 0.562"-0.578" for bass trombones.

Mouthpiece Edit

The mouthpiece is a separate part of the trombone and can be interchanged with similarly sized trombones from different manufacturers. Available mouthpieces for trombone (as with all brass instruments) vary in material composition, length, diameter, rim shape, cup depth, throat entrance, venturi aperture, venturi profile, outside design and other factors. Variations in mouthpiece construction affect the individual player's ability to make a lip seal and produce a reliable tone, the timbre of that tone, its volume, the player's subjective level of comfort, and the instrument's playability in a given pitch range.

Mouthpiece selection is a highly personal decision. Thus, a symphonic trombonist might prefer a mouthpiece with a deeper cup and sharper inner rim shape in order to produce a rich symphonic tone quality, while a jazz trombonist might choose a shallower cup in order to achieve brighter tone and easier production of higher notes. Further, for certain compositions, these choices between two such performers could easily be reversed.

Regional variations Edit

Germany and Austria Edit

German trombones have been built in a wide variety of bore and bell sizes. The traditional German Konzertposaune can differ substantially from American designs in many aspects. The mouthpiece is typically rather small and is placed into a slide section with a very long leadpipe of at least 12"-24". The whole instrument is often made of gold brass, and its sound is usually rather dull compared with British, French or American designs. While their bore sizes were considered large in the 19th century, German trombones have altered very little over the last 150 years and are now typically somewhat smaller than their American counterparts. Bell sizes remain very large in all sizes of German trombone and a bass trombone bell may exceed 10" in diameter. Valve attachments in tenor and bass trombones were traditionally engaged via a thumb-operated rotary valve, using a leather thong rather than a metal lever. While older models with this feature are still found, modern variants use the metal lever. As with other German and Austrian brass instruments, rotary valves are used to the exclusion of almost all other types of valve, even in valve trombones. Other features often found on German trombones include long water keys and snake decorations on the slide and bell U-bows.

Most trombones played in Germany today, especially by amateurs, are built in the American fashion, as those are much more widely available and thus far cheaper.

France Edit

French trombones were built in the very smallest bore sizes up to the end of the Second World War and whilst other sizes were made there, the French usually preferred the tenor trombone to any other size. French music, therefore, usually employed a section of three tenor trombones up to the mid-20th century. Tenor trombones produced in France during the 19th and early 20th centuries featured bore sizes of around 0.450", small bells of not more than 6" in diameter, as well as a funnel-shaped mouthpiece slightly larger than that of the cornet or horn. French tenor trombones were built in both C and B♭, altos in D♭, sopranos in F, piccolos in high B♭, basses in G and E♭, contrabasses in B♭.

Didactics Edit

In recent years, several makers have begun to market compact B♭/C trombones that are especially well suited for young children learning to play the trombone who cannot reach the outer slide positions of full-length instruments. The fundamental note of the unenhanced length is C, but the short valved attachment that puts the instrument in B♭ is open when the trigger is not depressed. While such instruments have no seventh slide position, C and B natural may be comfortably accessed on the first and second positions by using the trigger. A similar design ("Preacher model") was marketed by C.G. Conn in the 1920s, also under the Wurlitzer label. Currently, B♭/C trombones are available from many manufacturers, including German makers Günter Frost, Thein and Helmut Voigt, as well as the Yamaha Corporation.[5]

Manufacturers Edit

Trombones in slide and valve configuration have been made by a vast array of musical instrument manufacturers. For the brass bands of the late 19th and early 20th century, prominent American manufacturers included Graves and Sons, E.G. Wright and Company, The Boston Musical Instrument Company, E.A. Couturier Co., Ltd., H.N. White Company, J.W. York, and C.G. Conn, Ltd.. In the 20th Century, leading manufacturers of trombones included F.E. Olds, Vincent Bach, King Musical Instruments, Conn, F.A. Reynolds, Yamaha Musical Instruments, and recently Jupiter Band Instruments.
