The keyed bugle was very important to the development of brass bands. Keys allowed it to play chromatically decades before valves came into regular use. It could play soprano parts usually covered by clarinets, heralding bands made up entirely of brass instruments. The keyed bugle is a highly flexible instrument. Its conical mouthpiece and bore produce a mellow sound similar to the modern flugelhorn. The holes covered by the keys affect the tone, making some notes sound stronger than others.
