Read the passage.

Almost everyone knows “Taps,” the haunting melody played by a military bugler at military and memorial services. This tune has twenty-four solemn notes, one for each hour of the day, and all the notes are part of a single chord.

“Taps” had its beginnings in Europe. It . . . functioned as a kind of curfew call. It warned [soldiers who were late returning to their barracks] that they had only a short time to return to base. Troops who were roaming at liberty needed to report to their officers, or they would be disciplined.

One evening during the Civil War, General Daniel Butterfield, a Union officer, fondly and sympathetically recalled the French tune. Somehow, “Taps” had crossed the ocean. Butterfield made his speech to his comrades, asking those in the group that the melody be played each evening at sundown instead of a bugle named “Extinguish the Lights.” The tune soon spread to the Confederate army, and it was even played at the funeral of Confederate General Stonewall Jackson.

These days, “Taps” no longer symbolizes a curfew call. Instead, it functions as a solemn farewell. When its twenty-four notes ring out at a state occasion, mellow and true, they often bring tears to the eyes of the spectators in attendance.
