E-flat instruments

The keyed trumpet is a cylindrical-bore brass instrument in the trumpet family that makes use of tone holes operated by keys to alter pitch and provide a full chromatic scale, rather than extending the length of tubing with a slide or valves. It was developed from the natural trumpet in the 18th century and reached its high-point in popularity c.when two important trumpet concertos were written for it by Austrian composers Joseph Haydn and Johann Nepomuk Hummel, but waned with the invention of valves in the 1820s and the subsequent emergence of the modern valved trumpet. It is rarely seen in modern performances.

The saxtuba is an obsolete valved brass wind instrument conceived by the Belgian instrument-maker Adolphe Sax around 1845. The design of the instrument was inspired by the ancient Roman cornu and tuba. The saxtubas, which comprised a family of half-tube and whole-tube instruments of varying pitches, were first employed in Fromental Halévy's opera Le Juif errant (The Wandering Jew) in 1852. Their only other public appearance of note was at a military ceremony on the Champ de Mars in Paris in the same year. The term "saxtuba" may also refer to the bass saxhorn.

The saxotromba is a valved brass instrument invented by the Belgian instrument-maker Adolphe Sax around 1844. It was designed for the mounted bands of the French military, probably as a substitute for the French horn. The saxotrombas comprised a family of half-tube instruments of different pitches. By about 1867 the saxotromba was no longer being used by the French military, but specimens of various sizes continued to be manufactured until the early decades of the twentieth century, during which time the instrument made sporadic appearances in the opera house, both in the pit and on stage. The instrument is often confused with the closely related saxhorn.

The soprano cornet is a transposing brass instrument similar to the standard B♭ cornet but smaller and pitched a fourth higher in E♭.

The E-flat (E♭) clarinet is a member of the clarinet family, smaller than the more common B♭ clarinet and pitched a perfect fourth higher. It is typically considered the sopranino or piccolo member of the clarinet family and is a transposing instrument in E♭ with a sounding pitch a minor third higher than written. The E-flat clarinet has a total length of about 49 centimetres (19 in).

The contrabass saxophone is the second-lowest-pitched extant member of the saxophone family proper. It is pitched in E♭ one octave below the baritone saxophone, which requires twice the length of tubing and bore width. This renders a very large and heavy instrument, standing approximately 2 metres (6 ft 7 in) tall and weighing around 20 kilograms (44 lb). Despite this, it was used in marching bands in the early 20th century.

The alto clarinet is a woodwind instrument of the clarinet family. It is a transposing instrument pitched in the key of E♭, though instruments in F have been made. In size it lies between the soprano clarinet and the bass clarinet. It bears a greater resemblance to the bass clarinet in that it typically has a straight body (made of grenadilla or other wood, hard rubber, or plastic), but a curved neck and bell made of metal. All-metal alto clarinets also exist. In appearance it strongly resembles the basset horn, but usually differs in three respects: it is pitched a whole step lower, it lacks an extended lower range, and it has a wider bore than many basset horns.

The sopranino saxophone is the second-smallest member of the saxophone family. It is tuned in the key of E♭, and sounds an octave higher than the alto saxophone. A sopranino in F was also described in Adolphe Sax's patent, an octave above an F alto (mezzo-soprano), but there are no known built instruments.

The Tenor horn (British English; Alto horn in American English, Althorn in Germany; occasionally referred to as E♭ horn) is a brass instrument in the saxhorn family and is usually pitched in E♭. It has a bore that is mostly conical, like the flugelhorn and euphonium, and normally uses a deep, cornet-like mouthpiece.

The saxhorn is a family of valved brass instruments that have conical bores and deep cup-shaped mouthpieces. The saxhorn family was developed by Adolphe Sax, who is also known for creating the saxophone family. The sound of the saxhorn has a characteristic mellow tone quality and blends well with other brass.
