Harriet Tubman was born around 1822 on a plantation in Dorchester County, Maryland. Harriet Tubman was an escaped enslaved African American woman who became a guide on the Underground Railroad, leading enslaved African Americans to freedom through coded music as communication before the Civil War.
Singing as a form of communication is deeply rooted into the African American culture. Harriet Tubman being born into slavery and in the African American community, was accustomed to these types of songs that were passed down from ancestors throughout slavery. Most enslaved people were illiterates and used only music to express their feelings. Later when she had a chance to escape, she decided to free other enslaved people and that music would be the best way to communicate and lead them to freedom.
"I had reasoned this out in my mind; there was one of two things I had a right to, liberty, or death; if I could not have one, I would have the other; for no man should take me alive; I should fight for my liberty as long as my strength lasted, and when the time came for me to go, the Lord would let them take me."
