Though music had become ubiquitous in American life even before the Civil War, the conflict between North and South launched it to new heights of importance.

For the more than 3 million soldiers who joined the Union and Confederate armies from 1861-65, music provided a backdrop for their daily activities, lifted their spirits ahead of challenging battles and kept up much-needed morale as the war dragged on. For those on the home front, the music that emerged from the conflict served as a link to their loved ones, and eventually worked its way into the fabric of American life.

The Role of Music in the Military

Soldiers played a huge role in popularizing songs during the Civil War. Both Union and Confederate regiments would play and sing as they marched and in their camps, spreading their chosen songs to the communities they encountered around the country. In addition to the large military bands assigned to army units, smaller groups of field musicians played instruments such as fifes, drums and bugles to accompany the troops in their daily activities—from wakeup and roll call to drills and marches to light’s out—and even during battle. According to some estimates, the total number of military musicians who served during the war reached nearly 54,000.

Now familiar as the tune played at military funerals, and to end the day at U.S. Army bases, “Taps” first emerged in 1862, when a Union general worked with his brigade’s bugler to work out a new bugle call for lights-out. “Taps” spread quickly to other units in the Union Army, and was used for the first time at a military funeral during the Peninsular Campaign in Virginia later that year.

Popular Songs on Both Sides

The Civil War drove a boom in American songwriting: Historian Christian McWhirter estimates that between 9,000 and 10,000 songs were published as sheet music during the war, including some 2,000 in the first year of the conflict alone.

Out of the many patriotic anthems, sentimental love songs and energetic marching tunes that the war produced, each side had certain songs that were particularly popular among soldiers. Union favorites such as “John Brown’s Body,” “The Battle Cry of Freedom” and “We Are Coming, Father Abraham” exalted President Abraham Lincoln, the union of the states and the antislavery cause. For Confederate soldiers and citizens, songs such as “Dixie,” “Maryland, My Maryland” and “The Bonnie Blue Flag” glorified the Southern cause.

Some songs were popular on both sides, including the spirited tune “When Johnny Comes Marching Home,” which U.S. troops would later sing in World War I and World War II. While camped on opposite sides of the Rappahannock River in December 1862, a few weeks after the Battle of Fredericksburg, Union and Confederate troops reportedly joined together in singing the poignant ballad “Home Sweet Home.”

With Black soldiers making up nearly 10 percent of the Union Army by the end of the Civil War, the conflict also introduced many Union soldiers and other Northerners to African American music. In particular, former spirituals like “Go Down, Moses” (also known as “Let My People Go”) and “Michael, Row Your Boat Ashore” found a wider audience, though the lack of written music and recordings at the time meant that many Black musical traditions were lost to history.

The Legacy of 'Dixie'

Ironically, the most enduring song linked to the former Confederacy was written by a Northern composer. Daniel Emmett originally penned "Dixie" in Ohio in 1859 as the concluding number for a minstrel show. These performances, which were demeaning to African Americans, were a popular form of entertainment at the time and featured white performers, donned in blackface, acting out scenes of Southern life. The song became a popular hit before it was appropriated by the Confederacy as a patriotic anthem during the Civil War, with even President Lincoln later praising it as “one of the best tunes I have ever heard.”

Years after the war concluded, “Dixie” was embraced by white southerners seeking to revive the idyllic image of the Confederacy, along with white supremacy in the South. “‘Dixie’ was part of the score of Birth of a Nation, the movie that helped revive the Ku Klux Klan,” writer Tony Horwitz told NPR in 2018. “It was embraced by the segregationist Dixiecrats in the 1940s. And in the 1950s, it was sung by white women protesting the integration of schools in Arkansas and elsewhere.”

'The Battle Hymn of the Republic'

The story of one of the nation’s most enduring anthems began during the Civil War, when the poet and activist Julia Ward Howe visited Washington, D.C. in late 1861. While touring Union camps in northern Virginia, Howe heard them singing “John Brown’s Body,” which honored the radical abolitionist who was executed for leading a raid on Harper’s Ferry. That night, Howe was inspired to write new, more poetic lyrics to the song, publishing the result in February 1862 in the Atlantic Monthly.

Howe’s version, called “The Battle Hymn of the Republic,” became the version of the song we know best today, with its eloquent anti-slavery message, including the exhortation “Let us die to make men free.” As Andrew Limbong writes for NPR, later generations of very different Americans would use the Civil War-era anthem for their own purposes: The conservative activist Anita Bryant played it at anti-gay rallies, while Martin Luther King, Jr. quoted Howe’s words ("Mine eyes have seen the glory of the coming of the Lord") in his famous “I”ve Been to the Mountaintop” speech, delivered the day before he was killed in 1968.
