The tuba (Latin, "trumpet"; ; ) is a large brass instrument in the bass-to-contrabass range with a wide conical bore. It usually has four or five valves, although some models have three and some have six. It first appeared in 1835 in Prussia as the , by adding five valves to a large 12-foot bugle pitched in F. This design provided a fully chromatic contrabass instrument with a deep, full timbre. By the 1850s, Paris instrument designer Adolphe Sax had developed the E and B band tubas with piston valves as part of his saxhorn family, and in the 1870s Václav František Červený in Austria-Hungary d

The contrabassoon, also known as the double bassoon, is a larger version of the bassoon, sounding an octave lower. Its technique is similar to its smaller cousin, with a few notable differences.

The octobass is an extremely large and rare bowed string instrument first built around 1850 in Paris by the French luthier Jean-Baptiste Vuillaume (1798–1875). It has three strings and is essentially a larger version of the double bass – the specimen in the collection of the Musée de la Musique in Paris measures in length, whereas a full-size double bass is generally approximately in length.

The cimbasso ( , ) is a low brass instrument that covers the same range as a tuba or contrabass trombone. First appearing in Italy in the early 19th century as an upright serpent, the term cimbasso came to denote several instruments that could play the lowest brass part in 19th century Italian opera orchestras. The modern cimbasso design, first appearing as the in the 1880s, has four to six rotary valves (or occasionally piston valves), a forward-facing bell, and a predominantly cylindrical bore. These features lend its sound to the bass of the trombone family rather than the tuba, and its val

The tubax is a modified contrabass saxophone developed in 1999 by the German instrument maker Benedikt Eppelsheim. Eppelsheim's design uses the same fingering as the saxophone, while reducing the amount of expansion of its conical bore in relation to the length of tubing. This design modification results in a smaller volume of resonant air column, allowing the use of a smaller mouthpiece (baritone or bass size, instead of a larger contrabass mouthpiece), and more compactly folded tubing. The tubax exists in E♭ contrabass and B♭ or C subcontrabass sizes. Its name is a blend of the words "tuba"

The bass gehu (, ; also called digehu or beigehu , literally "bass gehu") is a Chinese bowed string instrument in the huqin family. It was developed by Yang Yusen along with the gehu in the 20th century. It has four strings and is the Chinese equivalent of the double bass.

The contraforte () is a proprietary instrument with a range similar to the contrabassoon produced by Benedikt Eppelsheim and Guntram Wolf. It is intended to have improved dynamics and intonation over the distinctive but sometimes reticent sound of the conventional contrabassoon. The contraforte uses a different and wider bore than the contrabassoon to produce a distinct tone; the sound is more even in strength and intonation across registers, remaining quite strong into the high register, unlike a contrabassoon. Also, it lacks the distinct "rattle" of a contrabassoon, although an appropriate r
