Bass trombone

The bass trombone (german: Bassposaune, it, trombone basso) 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.

History

The earliest bass trombones were the bass sackbuts, usually pitched in G, F, or E♭ below the B♭ tenor. They had a smaller bore and less flared bell than modern instruments, and a longer slide with an attached handle to allow slide positions otherwise beyond the reach of a fully outstretched arm. The earliest known surviving specimen is an instrument in G built in Germany in 1593. This instrument matches descriptions and illustrations by Praetorius from his 1614–20 ''Syntagma Musicum''. These bass sackbuts were sometimes called , , and (Old German, , referring to intervals below B♭), though sometimes ''quartposaune'' was used generally to refer to any of these. The in B♭ refers to a very large and unwieldy predecessor of the contrabass trombone, a full octave below the tenor.

Bass sackbuts were used in Europe during the Renaissance and early Baroque periods. By the 18th century the F and E♭ bass trombones were used in Germany, Austria and Sweden, and the E♭ bass trombone in France.

The "tenor-bass" trombone

German instrument maker Christian Friedrich Sattler in 1821 created an instrument he called the (), a tenor in B♭ built with the larger bore and mouthpiece from the F bass trombone. It facilitated playing bass trombone parts in the low register, but was missing notes below E. Treatise author Georges Kastner and other contemporary writers described a dissatisfaction with bass instruments in F or E♭, due to their slow and unwieldy slides. The invention of valves was quickly applied to create valve trombones in the 1830s which replaced the slide altogether; these became popular in military bands and Italian opera.

In 1839 Sattler invented the (), a F attachment, valve attachment for a B♭ tenor trombone to lower the instrument a fourth into F. Intended to bridge the range gap of the tenor trombone between E and B♭, it was quickly adopted for bass trombone parts, particularly in Germany. These instruments in B♭/F gradually replaced the larger bass trombones in F and E♭ over the course of the 19th and early 20th centuries. Late Romanticism, Romantic German composers specifying ''Tenorbaßposaune'' in scores intended a B♭/F trombone capable of playing below E; Arnold Schoenberg called for four in ''Gurre-Lieder (1911).

The bass trombone in Britain

From about the mid-nineteenth century, the bass trombone in G enjoyed a period of extended popularity in France and especially Britain. In brass bands in Britain, the G bass trombone was standard, built largely by makers Besson (music company), Besson and Boosey & Hawkes with no valves and a slide handle for reaching the longer sixth and seventh positions. For use in British orchestras from the early twentieth century, it was often built with a D or C valve attachment. The G bass trombone was in use until the 1950s, when London orchestral players began importing larger bore American B♭ instruments, particularly by C.G. Conn, Conn. The G trombone lingered on in some parts of Britain and former British colonies well into the 1980s, particularly in British brass band, brass bands and period instrument orchestras.

Recent developments

The modern bass trombone has evolved from the large-bore B♭/F tenor-bass trombones in the late 19th century. In the early 20th century, manufacturers attempted to solve the problem of the missing low B♮ on such instruments by adding a second valve. In the 1920s, manufacturers C.G. Conn, Conn and Holton (Leblanc), Holton made B♭/F bass trombones with a () that could lower the F tubing to E when manually set. The first true double-valve trombone (where the second valve can be operated while playing) was made by Olds in 1937, using a second ''dependent'' valve to lower the instrument to E, and having no effect alone.

In the 1950s, several bass trombonists in North American orchestras had double-valve instruments custom-built, and it is from these designs that the modern double-valve bass trombone has evolved. In 1956 Vincent Bach Corporation, Vincent Bach modified their bass trombone for Lawrence Weinman, then bass trombonist with Minneapolis Symphony. It added a dependent E valve similar to the Olds model. This instrument became the 50B2 model, first sold in 1961. In the late 1960s another design appeared using a second, ''independent'' valve that can be engaged separately to lower the instrument to G, and to E♭ when combined with the first. The first commercially available trombone to use independent valves was the Olds S-24G model in 1973. Although new to the bass trombone, this idea was anticipated in Germany in 1921 by Ernst Dehmel's design for a contrabass trombone in F with two independent valves.

Construction

The modern bass trombone uses the same length of tubing as the tenor trombone, but with a wider bore, a larger bell, and a larger mouthpiece which facilitate playing in the low register. Typical specifications are a bore size of in the slide with a bell from in diameter.

Dependent and independent valves

The bass trombone has typically two valves that lower the pitch of the instrument when engaged, to facilitate the register between the B♭₁ pedal in first position and the E₂ second partial in seventh. The first valve lowers the key of the instrument a fourth to F. The second (when engaged with the first) will lower the instrument to D (or less commonly, E♭).

The second valve can be configured in one of two ways, referred to as either "dependent" or "independent" (sometimes also called "in-line"). In a dependent system, the second valve is fitted to the tubing of the first valve, and can only be engaged in combination with the first. In an independent system, the second valve is fitted to the main tubing next to the first valve, and can be used independently. The second independent valve typically lowers the instrument to G♭, and D when engaged in tandem with the first valve. Less commonly the second valve is tuned to G (combining to give E♭), or has a tuning slide that can tune the valve to either G or G♭ as desired.

Single-valve instruments

The low B₁ note immediately above the pedal range is unobtainable on a standard trombone slide with a single valve in F. Bass trombones from the 19th and early 20th century were sometimes made with a valve attachment in E rather than F, or with an alternative tuning slide to lower the pitch to E♭. Today, single-valve bass trombones have a tuning slide on the valve section that is long enough to enable access to the low B₁ by lowering the pitch from F to E.

Range

The range of the modern bass trombone with two valves is fully chromatic from the lowest pedal tones, fundamental B♭ with both valves engaged (or even A with valve slides extended), up to at least B♭. Many professionals can extend the range even higher, though such demands may be taxing to the player. While much of the established orchestral repertoire infrequently strays below a B♭ or above a G, and is typically written for in the lower registers, high B♭ is called for in Béla Bartók, Bartók's ''The Miraculous Mandarin'' and Zoltán Kodály, Kodály's ''Háry János'' suite. Contemporary orchestral and solo classical pieces, as well as modern jazz arrangements, will often further exploit the wide tonal range of the bass trombone.

Repertoire

Since the Romantic music, Romantic period, the trombone section of an orchestra, Concert band, wind ensemble, or British brass band, British-style brass band usually consists of two tenor trombones and at least one bass trombone. In a modern jazz big band, at least one of the trombonists will play bass trombone, often serving as the anchor of the trombone section or doubling the double bass and baritone saxophone.

George Roberts (trombonist), George Roberts (affectionately known as "Mr. Bass Trombone") was one of the first players to champion the solo possibilities of the instrument. One of the first major classical solo works for the instrument was the Concerto for Bass Trombone by Thom Ritter George.
