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
Pitch of brass instruments valve that puts it into E, and when combined, these put the instrument into the key of B. The B contrabass is often fitted with a valve in F and has been fitted with both a valve in F and G, so that it matches its bass trombone counterpart, but is pitched an octave lower. See Types of trombones The bass tuba is commonly available in F and E, while contrabass tubas are available in C and B. Pitch of brass instruments The pitch of a brass instrument is determined by its vibratory length, which determines the fundamental frequency of
