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
Hans Felix Husadel alto slide trombone. Tenor and baritone Tuba were modified so their bells faced forward, with the mechanics of the instruments adjusted to allow better handling while on the march. The traditional rotary valves on bass trumpets were also replaced with pump valves. The openings of the higher pitched brass instruments were narrowed to achieve greater sharpness and clarity of sound. The effect was to give Husadel's Luftwaffe bands a unique timbre with strong and varied middle voices. Husadel’s bands chose silver-plated instruments, giving them a modern look compared to the standard army and navy band instrument brass finishes. Husadel's Luftwaffe
