Concord Hymn

"Concord Hymn" (original title was "Hymn: Sung at the Completion of the Concord Monument, April 19, 1838") is a poem by Ralph Waldo Emerson written for the 1837 dedication of the Obelisk, a monument in Concord, Massachusetts, commemorating the Battle of Concord, the second in a series of battles and skirmishes on April 19, 1775, at the outbreak of the American Revolution. 

The "Concord Hymn" was written at the request of the Battle Monument Committee. At Concord's Independence Day celebration on July 4, 1837, it was first read, then sung as a hymn by a local choir using the then-familiar tune "Old Hundredth".

The poem elevates the battle above a simple event, setting Concord as the spiritual center of the American nation, removes specific details about the battle itself, and exalts a general spirit of revolution and freedom— a spirit Emerson hoped would outlive those who fought in the battle. One source of the hymn's power may be Emerson's personal ties to the subject: his grandfather William Emerson, Sr., witnessed the battle at the North Bridge while living at the Old Manse.

Emerson's line "the shot heard round the world" is a fixture in the lore of the American Revolution.
