The Civil War songbook : complete original sheet music for 37 songs
Excerpt from "Confederate and Union Civil War Song Lyrics"
The story of the Civil War can be told entirely through the music of the time. Both sides sang songs about every aspect of the conflict. Music has long been important in the lives of all people. The Civil War soldiers and civilians were not exceptions. The average soldier had a lot of time on his hands. A favorite pastime was singing. Music gave soldiers a way to express their emotions and experiences. They sang in camp and on marches. There were songs for entertainment, to lift morale, to give courage and to remind them of their loved ones at home.
