Musical of the Day! – Trumpet


Introduction

The trumpet is a musical instrument with the highest register in the brass family. Trumpets are among the oldest musical instruments, dating back to at least 1500 BC. They are constructed of brass tubing bent twice into an oblong shape, and are played by blowing air through closed lips, producing a "buzzing" sound which starts a standing wave vibration in the air column inside the trumpet.

There are several types of trumpet; the most common is a transposing instrument pitched in B. The predecessors to trumpets did not have valves; however, modern trumpets have either three piston valves or three rotary valves, each of which increases the length of tubing when engaged, thereby lowering the pitch.

The trumpet is used in many forms of music, including classical music and jazz.

The earliest trumpets date back to 1500 BC and earlier. The bronze and silver trumpets from Tutankhamun's grave in Egypt, bronze lurs from Scandinavia, and metal trumpets from China date back to this period. Trumpets from the Oxus civilization (3rd millennium BC) of Central Asia have decorated swellings in the middle, yet are made out of one sheet of metal, which is considered a technical wonder. The Moche people of ancient Peru depicted trumpets in their art going back to 300 AD. The earliest trumpets were signaling instruments used for military or religious purposes, rather than music in the modern sense; and the modern bugle continues this signaling tradition.

In medieval times, trumpet playing was a guarded craft, its instruction occurring only within highly selective guilds. The trumpet players were often among the most heavily guarded members of a troop, as they were relied upon to relay instructions to other sections of the army.

Improvements to instrument design and metal making in the late Middle Ages and Renaissance led to an increased usefulness of the trumpet as a musical instrument. The natural trumpets of this era consisted of a single coiled tube, without valves. This only allowed for one overtone series at a time to be played. Changing keys required the player to swap out the crooks of the instrument. The development of the upper, "clarino" register by specialist trumpeters—notably Cesare Bendinelli—would lend itself well to the Baroque era, also known as the "Golden Age of the natural trumpet." During this period, a vast body of music was written for virtuoso trumpeters. The art was revived in the mid-20th century and natural trumpet playing is again a thriving art in Europe. The popularity of natural trumpets in the United States has waned considerably from its heyday in the 1960's and 70's.

The melody-dominated homophony of the classical and romantic periods relegated the trumpet to a secondary role by most major composers owing to the limitations of the natural trumpet. Berlioz wrote in 1844:

"Notwithstanding the real loftiness and distinguished nature of its quality of tone, there are few instruments that have been more degraded (than the trumpet). Down to Beethoven and Weber, every composer - not excepting Mozart - persisted in confining it to the unworthy function of filling up, or in causing it to sound two or three commonplace rhythmical formulae."

The attempt to give the trumpet more chromatic freedom in its range saw the development of the keyed trumpet, but this was a largely unsuccessful venture due to the poor quality of its sound.

The trumpet was slow to adopt the modern valves (invented around the mid 1830s), and its cousin the cornet would take the spotlight as solo instrument for the next hundred years. The symphonies of Mozart and Beethoven, even Brahms, were still played on natural trumpets. Crooks and shanks (removable tubing of various lengths) as opposed to keys or valves were standard, notably in France, into the first part of the 20th century. As a consequence of this late development of the instrument's chromatic ability, the repertoire for the instrument is relatively small compared to other instruments. The 20th century saw an explosion in the amount and variety of music written for the trumpet.

 

Construction
The trumpet is constructed of brass tubing bent twice into an oblong shape. The trumpet and trombone share a roughly cylindrical bore which results in a bright, loud sound. The bore is actually a complex series of tapers, smaller at the mouthpiece receiver and larger just before the flare of the bell begins; careful design of these tapers is critical to the intonation of the instrument. By comparison, the cornet and flugelhorn have conical bores and produce a more mellow tone.

As with all brass instruments, sound is produced by blowing air through closed lips, producing a "buzzing" sound into the mouthpiece and starting a standing wave vibration in the air column inside the trumpet. The player can select the pitch from a range of overtones or harmonics by changing the lip aperture and tension (known as the embouchure). Modern trumpets also have three piston valves, each of which increases the length of tubing when engaged, thereby lowering the pitch. The first valve lowers the instrument's pitch by a whole step (2 semitones), the second valve by a half step (1 semitone), and the third valve by one-and-a-half steps (3 semitones). When a fourth valve is present, as with some piccolo trumpets, it lowers the pitch a perfect fourth (5 semitones). Used singly and in combination these valves make the instrument fully chromatic, i.e., able to play all twelve pitches of Western music. The sound is projected outward via the bell.

The trumpet's harmonic series is closely matched to the musical scale, but there are some notes in the series which are a compromise and thus slightly off key; these are known as wolf tones. Some trumpets have a slide mechanism built in to compensate.

The mouthpiece has a circular rim which provides a comfortable environment for the lips' vibration. Directly behind the rim is the cup, which channels the air into a much smaller opening (the back bore or shank) which tapers out slightly to match the diameter of the trumpet's lead pipe. The dimensions of these parts of the mouthpiece affect the timbre or quality of sound, the ease of playability, and player comfort. Generally, the wider and deeper the cup, the darker the sound and timbre.

Types of trumpets
The most common type is the B trumpet, but low F, C, D, E, E, F, G and A trumpets are also available. The most common use of the C trumpet is in American orchestral playing, where it is used alongside the B trumpet. Its slightly smaller size gives it a brighter, more lively sound. Because music written for early trumpets required the use of a different trumpet for each key — they did not have valves and therefore were not chromatic — and also because a player may choose to play a particular passage on a different trumpet from the one indicated on the written music, orchestra trumpet players are generally adept at transposing music at sight, sometimes playing music written for the B trumpet on the C trumpet, and vice versa.

The standard trumpet range extends from the written F immediately below Middle C up to about three octaves higher. Traditional trumpet repertoire rarely calls for notes beyond this range, and the fingering tables of most method books peak at the C (high C) two octaves above middle C. Several trumpeters have achieved fame for their proficiency in the extreme high register, among them Lew Soloff, Andrea Tofanelli, Bill Chase, Maynard Ferguson, Roger Ingram, Wayne Bergeron, Anthony Gorruso, Dizzy Gillespie, Jon Faddis, Cat Anderson, James Morrison, Doc Severinsen and Arturo Sandoval. It is also possible to produce pedal tones below the low F, which is a device commonly employed in contemporary repertoire for the instrument.

The smallest trumpets are referred to as piccolo trumpets. The most common of these are built to play in both B and A, with separate leadpipes for each key. The tubing in the B piccolo trumpet is one-half the length of that in a standard B trumpet. Piccolo trumpets in G, F and even C are also manufactured, but are rarer. Many players use a smaller mouthpiece on the piccolo trumpet, which requires a different sound production technique from the B trumpet and can limit endurance. Almost all piccolo trumpets have four valves instead of the usual three — the fourth valve lowers the pitch, usually by a fourth, to facilitate the playing of lower notes. Maurice André, Håkan Hardenberger, and Wynton Marsalis are some well-known piccolo trumpet players.

Trumpets pitched in the key of G are also called sopranos, or soprano bugles, after their adaptation from military bugles. Traditionally used in drum and bugle corps, sopranos have featured both rotary valves and piston valves.

The bass trumpet is usually played by a trombone player, being at the same pitch. Bass trumpet is played with a trombone or euphonium mouthpiece, and music for it is written in treble clef.

The modern slide trumpet is a B trumpet that has a slide instead of valves. It is similar to a soprano trombone. The first slide trumpets emerged during the Renaissance, predating the modern trombone, and are the first attempts to increase chromaticism on the instrument. Slide trumpets were the first trumpets allowed in the Christian church.

The historical slide trumpet was probably first developed in the late fourteenth century for use in alta capella wind bands. Deriving from early straight trumpets, the Renaissance slide trumpet was essentially a natural trumpet with a sliding leadpipe. This single slide was rather awkward, as the entire corpus of the instrument moved, and the range of the slide was probably no more than a major third. Originals were probably pitched in D, to fit with shawms in D and G, probably at a typical pitch standard near A=466Hz. As no instruments from this period are known to survive, the details - and even the existence - of a Renaissance slide trumpet is a matter of some conjecture, and there continues to be some debate among scholars.

Some slide trumpet designs saw use in England in the eighteenth century.

The pocket trumpet is a compact B trumpet. The bell is usually smaller than a standard trumpet and the tubing is more tightly wound to reduce the instrument size without reducing the total tube length. Its design is not standardized, and the quality of various models varies greatly. It can have a tone quality and projection unique in the trumpet world: a warm sound and a voice-like articulation. Unfortunately, since many pocket trumpet models suffer from poor design as well as cheap and sloppy manufacturing, the intonation, tone color and dynamic range of such instruments are severely hindered. Professional-standard instruments are, however, available. While they are not a substitute for the full-sized instrument, they can be useful in certain contexts.

There are also rotary-valve, or German, trumpets, as well as alto and Baroque trumpets.

The trumpet is often confused with its close relative, the cornet, which has a more conical tubing shape compared to the trumpet's more cylindrical tube. This, along with additional bends in the cornet's tubing, gives the cornet a slightly mellower tone, but the instruments are otherwise nearly identical. They have the same length of tubing and, therefore, the same pitch, so music written for cornet and trumpet is interchangeable. Another relative, the flugelhorn, has tubing that is even more conical than that of the cornet, and an even richer tone. It is sometimes augmented with a fourth valve to improve the intonation of some lower notes.

Playing
Fingering

On any trumpet, cornet, or flugelhorn, pressing the valves indicated by the numbers below will produce the written notes shown - "OPEN" means all valves up, "1" means first valve, "1-2" means first and second valve simultaneously and so on. The concert pitch which sounds depends on the transposition of the instrument. Engaging the fourth valve, if present, drops any of these pitches by a perfect fourth as well. Within each overtone series, the different pitches are attained by changing the embouchure, or lip position and "firmness". Standard fingerings above high C are the same as for the notes an octave below (C is 1-2, D is 1, etc.)

-Note that the fundamental of each overtone series does not exist - the series begins with the first overtone. Notes in parentheses are the sixth overtone, representing a pitch with a frequency of seven times that of the fundamental; while this pitch is close to the note shown, it is slightly flat relative to equal temperament, and use of those fingerings is generally avoided.

The fingering schema arises from the length of each valve's tubing (a longer tube produces a lower pitch). Valve "1" increases the tubing length enough to lower the pitch by one whole step, valve "2" by one half step, and valve "3" by one and a half steps. This scheme and the nature of the overtone series create the possibility of alternate fingerings for certain notes. For example, third-space "C" can be produced with no valves engaged (standard fingering) or with valves 2-3. Also, any note produced with 1-2 as its standard fingering can also be produced with valve 3 - each drops the pitch by 1-1/2 steps. Alternate fingerings may be used to improve facility in certain passages. Extending the third valve slide when using the fingerings 1-3 or 1-2-3 further lowers the pitch slightly to improve intonation.

Extended technique
Yale trombone professor John Swallow noted that brass techniques expanded rapidly in the 20th century due to the innovations of jazz players. Contemporary music for the trumpet makes wide uses of extended trumpet techniques.

Flutter tonguing: The trumpeter rolls the tip of the tongue to produce a 'growling like' tone. It is achieved as if one were rolling an R in the Spanish language. This technique is widely employed by composers like Berio and Stockhausen.

Growling: While playing a note, clinching the back of the throat to partially obstruct the air, preventing it from flowing evenly. This creates a gargling sound, thus making a 'growling' sound from the bell. Utilized by many jazz players, not to be confused with flutter tonguing, where the tongue is 100% responsible for creating the sound desired.

Double tonguing: The player articulates using the syllables ta-ka ta-ka ta-ka

Triple tonguing: The same as double tonguing, but with the syllables ta-ta-ka ta-ta-ka ta-ta-ka.

Doodle tongue: The trumpeter tongues so lightly that the articulation is almost indistinguishable.

Glissando: Trumpeters can slide between notes by depressing the valve halfway or changing the lip tension. Modern repertoire makes extensive use of this technique.

Vibrato: Vibrato is often regulated in contemporary repertoire through specific notation. Composers can call for everything from fast, slow or no vibrato to actual rhythmic patterns played with vibrato.

Pedal tone: Composers have written for two and a half octaves below the low F#, which is at the bottom of the standard range. Extreme low pedals are produced by slipping the lower lip out of the mouthpiece. The technique was pioneered famously by Bohumir Kryl.

Microtones: Composers such as Scelsi and Stockhausen have made wide use of the trumpet's ability to play microtonally. Some instruments are even adapted with a 4th valve which allows for a quarter-tone step between each note.

Mute belt: Karlheinz Stockhausen pioneered the use of a mute belt, worn around the player's waist, to enable rapid mute changes during pieces. The belt allows the performer to make faster and quieter mute changes, as well as enabling the performer to move around the stage.

Valve tremolo: Many notes on the trumpet can be played in several different valve combinations. By alternating between valve combinations on the same note, a tremolo effect can be created. Berio makes extended use of this technique in his Sequenza X.

Noises: By hissing, clicking, or breathing through the instrument, the trumpet can be made to resonate in ways that do not sound at all like a trumpet. Noises sound a 1/2 step higher than they are notated, and often require amplification to be heard.

Preparation: Composers have called for the trumpet to be played under water, or with certain slides removed. It is increasingly common for all sorts of preparations to be requested of a trumpeter. Extreme preparations involve alternate constructions, such as double bells and extra valves.

Singing: Composers such as Robert Erickson and Mark-Anthony Turnage have called for trumpeters to sing during the course of a piece, often while playing. It is possible to create a multiphonic effect by singing and playing different notes simultaneously.

Split tones: Trumpeters can produce more than one tone simultaneously by vibrating the two lips at different speeds. The interval produced is usually an octave or a fifth.

Lip Trill or Shake: By rapidly varying lip tension, but not changing the depressed valves, the pitch varies quickly between adjacent harmonics. These are usually done, and more straight-forward to execute, in the upper register.

Instruction and method books
One trumpet method publication of long-standing popularity is Jean-Baptiste Arban's Complete Conservatory Method for Trumpet (Cornet). Other well-known method books include "Technical Studies" by Herbert L. Clarke, "Grand Method" by Louis Saint-Jacome, "Daily Drills and Technical Studies" by Max Schlossberg, and methods by Claude Gordon and Charles Colin. Vassily Brandt's Orchestral Etudes and Last Etudes is used in many college and conservatory trumpet studios, containing drills on permutations of standard orchestral trumpet repertoire, transpositions, and other advanced material. A common method book for beginners is the "Walter Beeler Method", and there have been several instruction books written by virtuoso Allen Vizzutti. The Breeze Eazy method is sometimes used to teach younger students, as it includes general musical information.

Players
The trumpet is used in many forms of music, though the most recognised players have been in the jazz field. Louis Armstrong, for example, was well known for his virtuosity with the trumpet. Armstrong's improvisations on his Hot Five and Hot Seven records were daring and sophisticated while also often subtle and melodic. Miles Davis is widely considered one of the most influential musicians of the 20th century. His trumpet playing was distinctive, with a vocal, clear tone that has been imitated by many. The phrasing and sense of space in his solos have been models for generations of jazz musicians. Dizzy Gillespie was a trumpet virtuoso and gifted improviser, building on the style of Roy Eldridge but adding new layers of harmonic complexity. Gillespie had an enormous impact on virtually every subsequent trumpeter, both by the example of his playing and as a mentor to younger musicians. Maynard Ferguson came to prominence playing in Stan Kenton's orchestra, before forming his own band in 1957. He was noted for being able to play accurately in a remarkably high register. While he was not the first trumpeter to play in the extreme upper register, he had a unique ability to play high notes with full, rich tone, power, and musicality. While regarded by some as showboating, Ferguson's tone, phrasing and vibrato was instantly recognizable and has been influential on and imitated by generations of amateur and professional trumpet players. A direct connection to Ferguson's style of playing continues in the work of the trumpeters who played with him, notably Roger Ingram, Wayne Bergeron, and Eric Miyashiro. Although some had believed that Ferguson was endowed with exceptional facial musculature, he often shared in interviews that his command of the upper registers was based mostly on breath control, something he had discovered as a youngster in Montreal.

Among the other great modern jazz trumpet players are Clifford Brown, Jon Faddis, Harry James, Wynton Marsalis, Freddie Hubbard, Lee Morgan, Chet Baker, Arturo Sandoval, Doc Severinsen, Fats Navarro, Woody Shaw, Tom Harrell, Nat Adderly, Nicholas Payton, Wallace Roney, Claudio Roditi, and Don Cherry.

Notable classical trumpeters include Maurice André, Roger Voisin, Armando Ghitalla, William Vacchiano, Adolph "Bud" Herseth, Charles Schlueter, Malcolm McNab, Sergei Nakariakov, Maurice Murphy, Hakan Hardenberger, Philip Smith, Rafael Méndez, and Wynton Marsalis.

Notable natural trumpet players include Valentine Snow for whom Handel wrote several pieces and Gottfried Reiche who was Bach's chief trumpeter.

The American orchestral trumpet sound is largely attributable to Adolph "Bud" Herseth's 53-year tenure with the Chicago Symphony Orchestra. Though he was not as prolific a teacher as some of his peers, his widely recorded sound became the standard for American orchestras.

A musician who plays the trumpet is called a trumpet player or trumpeter.

Musical pieces
The trumpet is used in a wide range of musical styles including ska, ska punk, classical, jazz, Rock, Blues, pop, rap, cuban music, mariachi and funk.

Solos
The chromatic trumpet was first made in the late 1700s. The repertoire for the natural trumpet and cornetto is extensive. This music is commonly played on modern piccolo trumpets, although there are many highly proficient performers of the original instruments. This vast body of repertoire includes the music of Gabrieli, Monteverdi, Bach, Vivaldi and countless other composers. Because the overtone series doesn't allow stepwise movement until the upper register, the tessitura for this repertoire is very high.

Joseph Haydn's Trumpet Concerto was one of the first for a chromatic trumpet, a fact shown off by some stepwise melodies played low in the instrument's range. Johann Hummel wrote the other great Trumpet Concerto of the Classical period, and these two pieces are the cornerstone of the instrument's repertoire. Written as they were in the infancy of the chromatic trumpet, they reflect only a minor advancement of the trumpet's musical language, with the Hummel concerto being the more adventurous piece by far. In the 20th century, trumpet repertoire expanded rapidly as composers embraced the almost completely untapped potential of the modern trumpet.

Musical of the Day! – Trombone


Introduction
Trombone is a musical instrument in the brass family. Like all brass instruments, it is a lip-reed aerophone. The trombone is usually characterised by a telescopic slide with which the player varies the length of the tube to change pitches, although the valve trombone uses three valves similar to those on a trumpet.

The word trombone derives from italian tromba and -one, so the name literally means "large trumpet". Trombones and trumpets share the important characteristic of having predominantly cylindrical bores. Therefore, the most frequently encountered trombones—the tenor and bass trombone—are the tenor and bass counterparts of the trumpet. They are both pitched in B—with the slide all the way in, the notes of the harmonic series based on B can be played—but trombones generally read music in concert pitch.

A person who plays the trombone is called a trombonist.

 

Construction
The trombone consists of a cylindrical tube bent into an elongated "S" shape in a complex series of tapers, the smallest being at the mouthpiece receiver, and the largest being at the throat of the bell, before the flare for the bell begins. 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 inserted into the mouthpiece receiver in the slide section, which consists of a leadpipe, inner and outer slide tubes, and bracing, known as inner and outer slide stays. While modern stays are soldered, sackbuts were made with loose, unsoldered stays, which remained the pattern for German trombones until the mid-20th century. The leadpipe contains the venturi, which is a small constriction of the air column, adding a certain amount of resistance and to a great extent dictating the tone of the instrument; leadpipes may be soldered in permanently or interchangeable, depending on the maker.

The 'slide', the defining feature of the 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 on a frequent basis. Additional tubing connects the slide to the bell of the instrument through a neckpipe, and bell or back bow. 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; 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 connected with valved or keyed instruments, since they can adjust intonation "on the fly" by subtly altering slide positions when necessary.

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

Renaissance and Baroque periods
Until the early 18th century, the trombone was called the sackbut in English, 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 is 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
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
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 andFriedrich 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, 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 approximately 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 vast 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
In the 20th Century the trombone maintained its important position 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 andLuciano 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. The best known trombone concertos from this period include works by Derek Bourgeois, Lars-Erik Larsson, Launy Grøndahl, Jan Sandström and Gordon Jacob.

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, etc. It can be part of smaller groups as well, such as brass quintets, quartets, or trios, or trombone trios, quartets, or choirs. Trombones are also common in swing, jazz, merengue, salsa, rock, R&B, and ska.
