the bugle is used mainly in the military where the bugle call is used to make announcements. a long time ago, the bugle was used in the cavalry to pass instructions from officers to soldiers during battle. in the bible, bugles are found in the time of moses, when god commanded moses to 'make two bugles of hammered silver' in numbers 10:1-3. they were used to assemble the leaders and to give marching orders to the camps.
