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
Horn (instrument) was challenged by rival instrument makers during his lifetime. Throughout the mid-1850s, he continued to experiment with the instrument's valve pattern. Later makers, particularly in America, altered the scale and designs sometimes to such an extent as to make it difficult to determine whether the larger sizes of the resulting instruments actually have descended from the saxhorn or the tuba. The tenor and baritone horns, amongst other sizes of instruments used in British brass bands, are members of the saxhorn family. The Wagner tuba is a rare brass instrument that is essentially a horn modified to have a larger bell
