"Taps" is a bugle call that is sounded as a signal for “lights out” at the end of a military day, and during patriotic memorial ceremonies and military funerals conducted by the United States Armed Forces. The official military version is played by a single bugle or trumpet, although other versions of the tune may be played in other contexts (e.g., the U.S. Marine Corps Ceremonial Music site has recordings of two bugle versions and one band version). It is also performed often at Girl Guide, Girl Scout, and Boy Scout meetings and camps. The tune is also sometimes known as "Butterfields Lullaby", or by the first line of the lyric, "Day Is Done". The duration may vary to some extent. Etymology "Taps" is derived from the same source as "Tattoo". "Taps" is sometimes said to originate from the Dutch taptoe, meaning "close the (beer) taps (and send the troops back to camp)". An alternative explanation, however, is that it carried over from a term already in use before the American Civil War. Three single, slow drum beats were struck after the sounding of the Tattoo or "Extinguish Lights". This signal was known as the "Drum Taps", "The Taps", or simply as "Taps" in soldiers' slang. History The tune is a variation of an earlier bugle call known as the "Scott Tattoo", which was used in the U.S. from 1835 until 1860. It was arranged in its present form by the Union Army Brigadier General Daniel Butterfield, a Medal of Honor recipient. Butterfield commanded the 3d Brigade, 1st Division, V Army Corps, Army of the Potomac while at Harrison's Landing, Virginia in July 1862, and wrote it to replace the customary firing of three rifle volleys at the end of burials during battle. Butterfield's version in July 1862 replaced a previous French bugle call used to signal "lights out". Butterfield's bugler, Oliver Wilcox Norton, of East Springfield, Pennsylvania, was the first to sound the new call. Within months "Taps" was used by both Union and Confederate forces. It was officially recognized by the United States Army in 1874. Captain John C. Tidball, West Point Class of 1848, started the custom of playing "Taps" at military funerals. In early July 1862 at Harrison's Landing, a corporal of Tidball's Battery A, 2nd U.S. Artillery, died. He was, Tidball recalled later, "a most excellent man". Tidball wished to bury him with full military
