Brass balanced composition and proper production temperatures and parameters to avoid long-term failures. The high malleability and workability, relatively good resistance to corrosion, and traditionally attributed acoustic properties of brass, have made it the usual metal of choice for construction of musical instruments whose acoustic resonators consist of long, relatively narrow tubing, often folded or coiled for compactness; silver and its alloys, and even gold, have been used for the same reasons, but brass is the most economical choice. Collectively known as brass instruments, these include the trombone, tuba, trumpet, cornet, baritone horn, euphonium, tenor horn, and French horn, and many
Tenor horn whole-bore brass instrument, most players can play some pedal tones, the fundamentals (first partials) of (at least) the shorter tubing lengths. Tenor horn parts are written in the treble clef. The tenor horn is an E transposing instrument written a major sixth above concert pitch: the tenor horn notation for middle C represents the E below middle C in concert pitch (E in scientific pitch notation). The instrument known today as the tenor/alto horn was developed in the 1840s by the Belgian instrument maker Adolphe Sax who, among other instrument design activities, designed two similar families of valved brass instruments,
