A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called labrosones or labrophones, from Latin and Greek elements meaning 'lip' and 'sound'.
The euphonium is a medium-sized, 3 or 4-valve, often compensating, conical-bore, tenor-voiced brass instrument that derives its name from the Ancient Greek word εὔφωνος euphōnos, meaning "well-sounding" or "sweet-voiced". The euphonium is a valved instrument. Nearly all current models have piston valves, though some models with rotary valves do exist.
The pitch of a brass instrument corresponds to the lowest playable resonance frequency of the open instrument. The combined resonances resemble a harmonic series. The fundamental frequency of the harmonic series can be varied by adjusting the length of the tubing using the instrument's valve, slide, key or crook system, while the player's embouchure, lip tension and air flow serve to select a specific harmonic from the available series for playing. The fundamental is essentially missing from the resonances and is impractical to play on most brass instruments, but the overtones account for most pitches.
The saxhorn is a family of valved brass instruments that have conical bores and deep cup-shaped mouthpieces. The saxhorn family was developed by Adolphe Sax, who is also known for creating the saxophone family. The sound of the saxhorn has a characteristic mellow tone quality and blends well with other brass.
The trombone is a musical instrument in the brass family. As with all brass instruments, sound is produced when the player's vibrating lips cause the air column inside the instrument to vibrate. Nearly all trombones use a telescoping slide mechanism to alter the pitch instead of the valves used by other brass instruments. The valve trombone is an exception, using three valves similar to those on a trumpet, and the superbone has valves and a slide.
The tuba is the largest and lowest-pitched musical instrument in the brass family. As with all brass instruments, the sound is produced by lip vibration – a buzz – into a mouthpiece. It first appeared in the mid-19th century, making it one of the newer instruments in the modern orchestra and concert band, and largely replaced the ophicleide. Tuba is Latin for "trumpet".
The bass trumpet is a type of low trumpet which was first developed during the 1820s in Germany. It is usually pitched in 8' C or 9' B♭ today, but is sometimes built in E♭ and is treated as a transposing instrument sounding either an octave, a sixth or a ninth lower than written, depending on the pitch of the instrument. Having valves and the same tubing length, the bass trumpet is quite similar to the valve trombone, although the bass trumpet has a harder, more metallic tone. Certain modern manufacturers that sell 'valve trombones' and 'bass trumpets' employ the same tubing, valves, and bell in different combinations; in these circumstances, the bass trumpet is nearly similar to the valve trombone.
Contrabass refers to several musical instruments of very low pitch—generally one octave below bass register instruments. While the term most commonly refers to the double bass, many other instruments in the contrabass register exist.
The valve trombone is a brass instrument in the trombone family that has a set of valves to vary the pitch instead of a slide. Although it has been built in sizes from alto to contrabass, it is the tenor valve trombone pitched in B♭ which has seen the most widespread use. The most common valve trombone has three piston valves, and plays just like a trumpet but an octave lower. They are built in either short or long form.
The serpent is a low-pitched early wind instrument in the brass family developed in the Renaissance era. It has a trombone-like mouthpiece, with tone holes and fingering like a woodwind instrument. It is named for its long, conical bore bent into a snakelike shape, and unlike most brass instruments is made from wood with an outer covering of leather. A distant ancestor of the tuba, the serpent is related to the cornett and was used for bass parts from the 17th to the early 19th centuries.
The superbone is a hybrid tenor trombone in B♭ that has both a slide like a regular trombone and a set of valves like a valve trombone.
The bass trombone is the bass instrument in the trombone family of brass instruments. Modern instruments are pitched in the same B♭ as the tenor trombone but with a larger bore, bell and mouthpiece to facilitate low register playing, and usually two valves to fill in the missing range immediately above the pedal tones.
The ophicleide is a family of conical-bore keyed brass instruments invented in early 19th-century France to extend the keyed bugle into the alto, bass and contrabass ranges. Of these, the bass ophicleide in C or B♭ took root over the course of the 19th century in military bands and as the bass of orchestral brass sections throughout Western Europe, replacing the serpent and its later upright derivatives. By the end of the 19th century however, it had been largely superseded by early forms of the modern tuba, developed from valved ophicleides.
The alto trombone is the alto member of the trombone family of brass instruments, smaller than the tenor trombone. It is almost always pitched in E♭ a fourth higher than the tenor, although examples pitched in F are occasionally found. The alto trombone was commonly used from the 16th to the 18th centuries in church music to strengthen the alto voice, particularly in the Mass. Alto trombone parts are usually notated in alto clef.
Marching brass instruments are brass instruments specially designed to be played while moving. Most instruments do not have a marching version - only the following have marching versions:
The contrabass trombone is the lowest-pitched instrument in the trombone family of brass instruments. While modern instruments are pitched in 12 ft F with a single slide, the first practical contrabass trombones appeared in the mid-19th century built in 18′ B♭ an octave below the tenor trombone with a double slide. German opera composer Richard Wagner notably called for this instrument in his Der Ring des Nibelungen opera cycle in the 1870s, and contrabass trombone has since appeared occasionally in large orchestral works without becoming a permanent member of the modern orchestra.
The contrabass trumpet is the lowest-pitched member of the trumpet family, sounding below the bass trumpet. Only a few exist. The instrument appeared in the mid-20th century and has no orchestral or jazz repertoire. Usually built in 12' F a perfect fourth below the B♭ bass trumpet, it has the same length as the F contrabass trombone, cimbasso, or tuba. Some are built larger in 18' B♭— an octave below the bass trumpet and two octaves below the standard B♭ trumpet.
A horn is any of a family of musical instruments made of a tube, usually made of metal and often curved in various ways, with one narrow end into which the musician blows, and a wide end from which sound emerges. In horns, unlike some other brass instruments such as the trumpet, the bore gradually increases in width through most of its length—that is to say, it is conical rather than cylindrical. In jazz and popular-music contexts, the word may be used loosely to refer to any wind instrument, and a section of brass or woodwind instruments, or a mixture of the two, is called a horn section in these contexts.
Igor Krivokapič is a Slovenian composer, retired tubist and instrument inventor.
Václav František Červený was a Czech brass instrument maker and inventor. He became the principal manufacturer in Austria-Hungary.
