The trombone has a predominantly cylindrical bore like the trumpet, in contrast to the more conical brass instruments like the cornet, the flugelhorn, the baritone, and the euphonium.
[1] The German "Posaune" long predates the invention of the slide and could refer to a natural trumpet as late as the early fifteenth century.
Bach called for a tromba di tirarsi, which may have been a form of the closely related slide trumpet, to double the cantus firmus in some liturgical cantatas.
Aside from solo parts, Mozart's orchestration usually features a trio of alto, tenor and bass trombones, doubling the respective voices in the choir.
While its use declined in German and French orchestras, the valve trombone remained popular in some countries, including Italy and Bohemia, almost to the exclusion of the slide instrument.
These bands played a limited repertoire that consisted mainly of orchestral transcriptions, arrangements of popular and patriotic tunes, and feature pieces for soloists (usually cornetists, singers, and violinists).
A notable work for wind band is Berlioz's 1840 Grande symphonie funèbre et triomphale, which uses a trombone solo for the entire second movement.
Several composers wrote works for Queisser, including Mendelssohn's concertmaster Ferdinand David, Ernst Sachse, and Friedrich August Belcke.
Queisser championed and popularized Christian Friedrich Sattler's tenor-bass trombone during the 1840s, leading to its widespread use in orchestras throughout Germany and Austria.
Trombones have a short tuning slide in the U-shaped bend between the neckpipe and the bell, a feature designed by the French maker François Riedlocker in the early 19th century.
The valve attachment aids in increasing the lower range of the instrument, while also allowing alternate slide positions for difficult music passages.
While originally seen as a gimmick, these plastic models have found increasing popularity of the last decade and are now viewed as practice tools that make for more convenient travel as well as a cheaper option for beginning players not wishing to invest so much money in a trombone right away.
Other features often found on German trombones include long water keys as well as Schlangenverzierungen (snake decorations) on the slide and bell U-bows to help protect the tubing from damage.
Tenor trombones produced in France during the 19th and early 20th centuries featured bore sizes of around 0.450 in (11.4 mm), small bells of not more than 6 in (15 cm) in diameter, as well as a funnel-shaped mouthpiece slightly larger than that of the cornet or horn.
Since the late 20th century however, it has largely been supplanted by a less cumbersome single-slide bass-contrabass instrument pitched in 12' F. With two valve attachments to provide the same full range as its predecessor, this design is effectively a modern bass trombone built down a perfect fourth.
Although the contrabass has only appeared occasionally in orchestral repertoire and is not a permanent member of the modern orchestra, it has enjoyed a revival in the 21st century, particularly in film and video game soundtracks.
As the trombone in its simplest form has neither crooks, valves nor keys to lower the pitch by a specific interval, trombonists use seven chromatic slide positions.
The term cimbasso first appeared in early 19th century Italian opera scores, and originally referred to an upright serpent or an ophicleide.
The cimbasso is most commonly used in performances of late Romantic Italian operas by Verdi and Puccini, but has also experienced a 21st-century revival in film, television and video game soundtracks.
It has been reinvented several times since first appearing in the 19th century by Besson, and later Conn. Jazz trombonist and machinist Brad Gowans invented his "valide trombone" in the 1940s with a short four-position slide.
The term "sackbut" refers to the early forms of the trombone commonly used during the Renaissance and Baroque eras, with a characteristically smaller, more cylindrically proportioned bore, and a less-flared bell.
[33] In the modern system, each successive position outward (approximately 3+1⁄4 inches [8 cm]) will produce a note which is one semitone lower when played in the same partial.
Tightening and loosening the lips will allow the player to "bend" the note up or down by a semitone without changing position, so a slightly out-of-position slide may be compensated for by ear.
As with all brass instruments, progressive tightening of the lips and increased air pressure allow the player to move to different partial in the harmonic series.
[18] Although much of Western music has adopted the even-tempered scale, it has been the practice in Germany and Austria to play these notes in position, where they will have just intonation (see harmonic seventh as well for A♭4).
The B♭ pedal tone 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 tenor trombonists.
[18]: 151 The trombone glissando can create remarkable effects, and it is used in jazz and popular music, as in the famous song "The Stripper" by David Rose and his orchestra.
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).
Currently, B♭/C trombones are available from many manufacturers, including German makers Günter Frost, Thein and Helmut Voigt, as well as the Yamaha Corporation.
In the 21st century, leading mainstream manufacturers of trombones include Bach, Conn, Courtois, Edwards, Getzen, Jupiter, King, Rath, Schilke, S.E.
