The tuba is the lowest-sounding member of the brass family: a wide, conical tube of twelve to eighteen feet folded into an upright shape, sounded with a large cup mouthpiece and pitched with three to six valves. Patented in Berlin in 1835 and developed alongside similar instruments in the following decade, it took over the bass line once held by the serpent and ophicleide, and it now anchors orchestras, bands and brass ensembles.
A patent, a bass line, and a crowded decade
Before valves, the bass voice of wind bands and orchestras came from the serpent and later the ophicleide, keyed instruments that were hard to play in tune and uneven in tone. Valves, developed in German-speaking lands in the 1810s and 1820s, let a wide conical brass tube sound every note with consistent colour. In Berlin, the military music director Wilhelm Wieprecht and the instrument maker Johann Gottfried Moritz received a Prussian patent in 1835 for a bass tuba in F, generally regarded as the first instrument of its modern type.
Few inventions are the work of one pair, and the tuba was part of a wider movement. During the 1840s makers in several countries were building valved bass brass, and by about 1845 the Bohemian maker Václav Červený had developed valved contrabass tubas in B♭. Adolphe Sax’s saxhorns in Paris formed a parallel family. The tuba entered orchestras gradually, and by the later nineteenth century it was a regular member of symphonic and military ensembles.
Tubing you could walk the length of
A tuba is a long, widening cone of brass folded into a compact upright shape. Sizes are named by pitch: the F and E♭ tubas use roughly twelve to thirteen feet of tubing, the C tuba about sixteen, and the contrabass in B♭ about eighteen. A large cup mouthpiece sits at one end and an upward-facing bell at the other, and the instrument rests on the player’s lap or on a stand beside the chair.
Three to six valves add tubing; the fourth and fifth usually lower the pitch further and help intonation in the lowest register. Rotary valves, which turn to redirect air, are common in Germany and much of central Europe, while piston valves are standard in Britain, although practice varies by orchestra and player. Some instruments use compensating valves, in which extra loops correct notes that would otherwise sound flat when valves are combined.
The physics of a very long note
Low notes are slow. E1, near the bottom of the ordinary tuba range, vibrates about forty-one times per second, so a single wave stretches more than eight metres through the air. The tuba’s wide conical bore supports this slow vibration with a full-bodied, rounded tone. Players supply large volumes of air at gentle pressure, rather than the narrow, fast stream that suits a trumpet.
Because the lips buzz so slowly, the lowest notes take a moment to speak, and experienced players often begin them fractionally early. The instrument is capable of real delicacy, from soft sustained chords to quiet melodies. In an orchestra it typically supplies the floor beneath the trombones, with a mellow edge that blends with the brass rather than overpowering it.
Bass clef, sounding as written
Tuba parts are non-transposing: a written note sounds at that pitch, almost always in bass clef. The standard range of a B♭ contrabass is roughly E1 to B♭3, with pedal tones below and skilled players reaching far higher. The larger BB♭ and CC instruments give the deepest sound; the smaller F tuba is chosen when a lighter tone or a higher register is wanted.
Timbre changes less across this compass than on smaller brass, but it does shift. The lowest register is dark and diffuse, the middle resonant and singing, and the upper notes thinner and more strained. Orchestral composers have often used the tuba for foundation, punctuation and occasional solos, and twentieth-century works, such as Ralph Vaughan Williams’s concerto of 1954, show its lyrical side.
Breath as architecture
Players usually sit, holding the instrument upright against the lap and chest, and begin every phrase with a large, relaxed breath. On a typical four-valve tuba the valves lower the pitch by a whole step, a half step, a minor third and a perfect fourth respectively, so the same note can often be fingered several ways, and players choose the one that sounds best in tune.
Practice centres on long tones to even out the sound, flexibility exercises that slur across harmonics, and clear articulation, since a short note on so large an instrument needs a quick, light touch of the tongue. Many tuba players also perform on the euphonium or the smaller F tuba, and orchestral players may change instruments within a single program to suit the repertoire.
Cousins and wearable tubas
The euphonium, sometimes called the tenor tuba, is pitched in B♭ an octave above the B♭ contrabass and has a similar wide conical bore; the baritone horn is a slimmer cousin. Both descend from the saxhorn and tuba families of the 1840s. Bass tubas in E♭ and F, often played with orchestral brass, occupy the middle ground between the euphonium and the largest contrabass instruments.
Marching bands need an instrument that can be carried. The helicon wraps around the player’s body, resting on one shoulder, and the sousaphone, which takes its name from the American bandmaster John Philip Sousa, who is credited with encouraging its development in the 1890s, adds a forward-facing bell. Modern versions are often made of lightweight fibreglass, which reduces weight but changes the sound slightly.
Bands, quintets and New Orleans streets
In the symphony orchestra the tuba usually sits at the bottom of the brass section, joining the trombones in chorale passages and thickening the bass line. Wind bands and British-style brass bands depend on tubas heavily; brass bands call their tubas basses and pitch them in E♭ and B♭. Brass quintets, with two trumpets, horn, trombone and tuba, give the instrument a more exposed and melodic role.
In early New Orleans brass bands, tubas and sousaphones often supplied the bass line, a role later shared with the double bass as jazz moved indoors. Central European dance and village bands also use the instrument, and in orchestral writing the solo in Ravel’s arrangement of Mussorgsky’s Pictures at an Exhibition is commonly played on a euphonium or tenor tuba rather than on the larger instrument.
Maintenance on a large scale
Tuba valves need regular oil or grease and gentle handling, since the heavy rotors and long linkages are sensitive to dirt. Players empty condensation through water keys or slides after each session, and they clean the mouthpiece regularly. A periodic bath in lukewarm water for the whole instrument removes buildup inside the bore that can affect response.
Size creates its own risks. A dented bell or bent bow can change the sound, and the long tubing is easy to knock. Most players transport tubas in padded cases or bags, lift them by the body rather than the bell or bell brace, and store them on stands that keep weight off the delicate valve section.
Small facts worth knowing
- The word tuba comes from Latin, where it named a straight Roman trumpet, a very different instrument.
- Accounts commonly describe the first bass tuba of 1835 as using a new kind of piston valve devised in Berlin.
- The Horniman Museum holds a double bass tuba in E♭ made by a French military supplier and stamped with the date of the 1889 Paris Exposition.
- The Horniman also preserves a giant tuba that once served as a shop sign on a London instrument factory.
