Why did bugles plays drums in battle

During the Revolutionary War, armies didn’t have radios to talk to each other with. Music was the main way for them to communicate over long distances. It is widely recognized that the use of the fife and drum came from the armies of Switzerland, hundreds of years before America was discovered by Europeans. The fife was used because of its high pitched sound and the drum because of its low pitched sound. Both instruments can be heard from great distances and even through the sounds of a battlefield. Fifers and drummers would provide the music for all of the things that soldiers would need to do throughout the day. They would play tunes in the camp, on the battlefield, or for a march.
