EUPHONIUM (Fr. baryton; Ger. See also:Tenor See also:Tube)  , a See also:modern See also:brass See also:wind See also:instrument, known in military bands as See also:euphonium and in the See also:orchestra as See also:tuba . The euphonium consists of a brass See also:tube with a conical See also:bore of wide calibre ending in a wide-mouthed See also:bell; it is played by means of a See also:cup-shaped See also:mouthpiece . The See also:sound is produced as in the See also:bombardon, which is the See also:bass of the euphonium, by the varied tension of the lips across the mouth- ' For a discussion of this see See also:ARCHON.piece, whereby the natural open notes or harmonics, consisting of the See also:series here shown, are obtained . The intervening notes of the See also:chromatic See also:scale are obtained by means of valves or pistons usually four in number, which by opening a passage into additional lengths of tubing See also:lower the See also:pitch =-m . i H Meemhnn — one, See also:half, one-and-a-half, -mi4' 4i two-and-a-halftones (see b~_ T BOMBARDON; TUBA; I z 3 4 6 8 VALVES) . The euphonium gives out the fundamental, or first See also:note of the See also:harmonic series, readily, but no harmonic above the eighth . Euphoniums are made in C and in Bb, the latter being more generally used . By means of all the valves used at once, the Bb, an See also:octave below the fundamental, can be reached, giving a See also:compass of four octaves, with chromatic intervals . The bass clef is used in notation . The euphonium is treated by See also:French and See also:German composers as a transposing instrument; in See also:England the real notes are usually written, except when the See also:treble clef is used . The quality of See also:tone is See also:rich and full, harmonizing well with that of the See also:trombone . The euphonium speaks readily in the lower See also:register, but slowly, of course, owing to the See also:long See also:dip of the pistons . Messrs Rudall See also:Carte have removed this difficulty by their patent See also:short See also:action pistons, which have but half the dip of the old pistons .

instruments it is easy to execute rapid passages . The euphonium is frequently said to be a See also:saxhorn, corresponding to the baryton member of that See also:family, but the statement is misleading . The bombardon and euphonium, like the saxhorns, are the outcome of the application of valves to the See also:bugle family, but there is a See also:radical difference in construction; the tubas (bombardon and euphonium) have a conical bore of sufficiently wide calibre to allow of the See also:production of the fundamental harmonic, which is absent in the saxhorns . The Germans classify brass wind instruments as whole and half' according to whether, having the wide bore of the bugle, the whole length of the tube is available and gives the fundamental proper to an See also:organ See also:pipe of the same length or whether by See also:reason of the narrow bore in proportion to the length, only half the length of the instrument is of See also:practical utility, the harmonic series beginning with the second harmonic .
