contrabass bugle

Because the contrabass bugle can get in the way of commonly worn headgear, such as a shako, it is not uncommon for contrabass players to wear a beret instead of whatever else the rest of the ensemble is wearing for headgear. This also gives the players some distinction from the rest of the brass ensemble.

The first contrabass bugle was developed in the 1960s by Whaley Royce, a Canadian instrument manufacturer which produced bugles for many drum corps of that era. Matching all other competition bugles at the time, these early contrabass bugles were pitched in the key of GG, making them significantly larger than all tubas to that date, apart from the rare subcontrabass tuba. 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 piston valve and one 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 BBflat and CC were produced by instrument manufacturers for marching bands who wished to possess the sound of these contrabass bugles, generally regarded as "darker", without losing hornline sonority by having the basses in a different overtone series from the rest of the hornline (or requiring marching tubists to learn another set of fingerings for tuba parts originally written for BBflat and CC instruments). In the 2000s, contrabass bugles often have three or four valves, as is 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.

With most circuits now permitting B♭, C, and F instruments, the modern contrabass bugle is essentially a concert tuba converted for ease of marching. Generally, the primary differences between pure concert tubas and contrabass bugles are • 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 (which has earned it the nicknames of "shoulder rocket" and "shoulder cannon"), rather than in front of the player. On some "Marching-Convertible" models, this leadpipe can be unscrewed and replaced with a concert model. • All dedicated marching instruments have the valve section rotated into a more comfortable playing position. Some lower-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 hornlines.
