Raindrops on a bugle in Arlington National Cemetery as captured during a rainstorm by our @arlingtonmedia team. The bugle is one of the simplest brass instruments, having no valves or other pitch-altering devices. All pitch control is done by varying the player’s embouchure. Consequently, the bugle is limited to notes within the harmonic series. The bugle is used mainly in the military and Boy Scouts, where the bugle call is used to indicate the daily routines of camp. Historically the bugle was used in the cavalry to relay instructions from officers to soldiers during battle. They were used to assemble the leaders and to give marching orders to the camps. The Rifles, an infantry regiment in the British Army, has retained the bugle for ceremonial and symbolic purposes. The bugle has also been used as a sign of peace in the case of a surrender.
