The bugle is a small brass instrument that is basically a natural horn, because it has no valves or keys. One might wonder how the pitch is altered without any keys or valves; the pitch can be altered by controlling the air that the musician is blowing into the horn through closed lips. Blowing through closed lips is what creates the vibrations that make the sound. Of course, even with the ability to alter pitch manually without keys or valves, the instrument is fairly limited to a smaller range of notes it can make; which appears to be five notes at most.
