Contrabass Bugle
From Wikipedia, the free encyclopedia
The Contrabass Bugle, usually shortened to Contra, is the lowest-pitched instrument in the drum and bugle corps hornline. It is essentially drum corps' counterpart to the marching band's sousaphone: the lowest-pitched member of the hornline, and a replacement for the concert tuba on the marching field. It is different from the other members of the marching band and drum corps hornlines in that it rests on the shoulder of the player, rather than being held in front of the body.

[edit] History
The first contrabass was developed in the 1960s by Whaley Royce, a Canadian instrument manufacturer who produced bugles for many drum corps of that era. As with all competition bugles at the time, these early contras were pitched in the key of G, making them signifcantly larger than all tubas to that date, save the monstrous, and fairly uncommon, EE♭ and (almost fictional) BBB♭ concert tubas used in some brass bands. The contrabass bugle is the only member of the drum corps bugle line that has never been produced in a valve-less style, as it was developed when the drum corps rules allowed one 2-semitone piston valve and one 1-semitone rotary valve. They changed to fit new rules along with the rest of the drum corps hornline, first receiving two vertical (or in this case, slanted for ease of use) piston valves, then 3 and later 4 valves to make the instrument fully chromatic.
Equivalent instruments in the key of BB♭ and C were produced by instrument manufacturers for marching bands who wished to possess the sound of these contras, generally regarded as "darker", without losing hornline sonority by having the basses in a different overtone series from the rest of the hornline.
[edit] Construction and Naming
With most circuits now permitting B♭ and C instruments, the modern contra is essentially a concert tuba converted for ease of marching. Generally, the primary differences between pure concert tubas and contras are: 1. On both pure marching and convertible tubas, the concert leadpipe, with the pipe curving around the bell to the valves, is replaced with one that curves forward and back, placing the mouthpiece in an appropriate location for the new playing position, on the left (or occasionally, right) shoulder, rather than in front of the player. On some "Marching-Convertible" models, this leadpipe can be unscrewed and replaced with a concert model. 2. All dedicated marching instruments have the valve section rotated into a more comfortable playing position. Some higher-end convertible tubas have the capacity to rotate the valve section between marching and concert configurations.
Although historically (see below), drum and bugle corps contras were pitched in G, the construction was nearly identical to modern B♭ and C instruments, the only differences being the length and diameter of the tubing and (at one time) the valve section. In fact, modern drum corps now use multi-key instruments originally developed several years ago for marching bands who wished to emulate the sound of contemporary (G-instrumented) drum corps horn lines.
[edit] Modern Times
Today contras can be seen with three or four valves, as are common on concert tubas. Like most of their concert counterparts, they are pitched in either C or BB♭, although within the dwindling number of drum corps still using older instruments, they are, like the rest of the traditional bugle line, pitched in the key of G (or GG, depending on which naming convention is used). Instruments in any of these keys are generally larger in modern times compared to their older counterparts, although improved materials and construction techniques in the manufacture of instruments allows them to be made stronger and lighter than before.
