context_page_description: 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 euphonium may be played in bass clef as a non-transposing instrument or in treble clef as a transposing instrument. In British brass bands, it is typically treated as a treble-clef instrument, while in American band music, parts may be written in either treble clef or bass clef, or both.
context_section_description: The euphonium, like the tenor trombone, is pitched in concert B♭. For a valved brass instrument like the euphonium, this means that when no valves are in use the instrument will produce partials of the B♭ harmonic series. It is generally orchestrated as a non-transposing instrument like the trombone, written at concert pitch in the bass clef with higher passages in the tenor clef. Treble clef euphonium parts transposing down a major ninth are included in much concert band music: in the British-style brass band tradition, euphonium music is always written this way. In continental European band music, parts for the euphonium may be written in the bass clef as a B♭ transposing instrument sounding a major second lower than written.
  Professional models have three top-action valves, played with the first three fingers of the right hand, plus a "compensating" fourth valve, generally found midway down the right side of the instrument, played with the left index finger; such an instrument is shown at the top of this page. Beginner models often have only the three top-action valves, while some intermediate "student" models may have a fourth top-action valve, played with the fourth finger of the right hand. Compensating systems are expensive to build, and there is in general a substantial difference in price between compensating and non-compensating models. For a thorough discussion of the valves and the compensation system, see the article on brass instruments.
  The euphonium has an extensive range, comfortably from E₂ to about E♭₄ for intermediate players (using scientific pitch notation). In professional hands this may extend from B₀ to as high as B♭₅. The lowest notes obtainable depend on the valve set-up of the instrument. All instruments are chromatic down to E₂, but four-valved instruments extend that down to at least C₂. Non-compensating four-valved instruments suffer from intonation problems from E♭₂ down to C₂ and cannot produce the low B₁; compensating instruments do not have such intonation problems and can play the low B₁. From B♭₁ down lies the "pedal range", i.e., the fundamentals of the instrument's harmonic series. They are easily produced on the euphonium as compared to other brass instruments, and the extent of the range depends on the make of the instrument in exactly the same way as just described. Thus, on a compensating four-valved instrument, the lowest note possible is B₀, sometimes called double pedal B, which is six ledger lines below the bass clef.
  As with the other conical-bore instruments, the cornet, flugelhorn, horn, and tuba, the euphonium's tubing (excepting the tubing in the valve section, which is necessarily cylindrical) gradually increases in diameter throughout its length, resulting in a softer, gentler tone compared to cylindrical-bore instruments such as the trumpet, trombone, sudrophone, and baritone horn. While a truly characteristic euphonium sound is rather hard to define precisely, most players would agree that an ideal sound is dark, rich, warm, and velvety, with virtually no hardness to it. This also has to do with the different models preferred by British and American players.
  Though the euphonium's fingerings are no different from those of the trumpet or tuba, beginning euphoniumists will likely experience significant problems with intonation, response and range compared to other beginning brass players. In addition, it is very difficult for students, even of high-school age, to develop the rich sound characteristic of the euphonium, due partly to the instrument models used in schools and partly to the lack of awareness of good euphonium sound models.
