Keyed Bugle
The keyed bugle is a brass instrument whose approach to chromatic music resembles that of a woodwind. Instead of valves, it uses keys covering tone holes. This approach to pitch was popular in the nineteenth-century Germany, but was later superseded by valved brass instruments, which are easier and more accurate to play. The ophicleide is a keyed bugle that has been extended into a lower tonal range. This instrument has been completely flattened, the bell is dented, the tubing is badly deformed, and the keys are bent, some of them partially broken.
