A bugle is a small brass instrument that has fewer or no valves compared to a trumpet. As a result, there is a small variation between the notes, and so the sound is quite consistent. A bugle has historically been used to announce the arrival of important people or as a call in military tradition before the invention of electronic communications. It is still used for ceremony in military and civilian camps. If your business runs a camp for youth, then it might be practical to find a track of bugle calls.
It is not difficult to find a good sample of bugle choruses if you visit the right web site. Purchasing a CD can be convenient because it features calls for different situations and purposes, some of which the operator of a camp might not even know about. It is much more practical than having a member of staff learning to use a bugle, especially in a seasonal business.
