That's The Blues

The phrase "the blues" was written by Charlotte Forten, then aged 25, in her diary on December 14, 1862. She was a free-born black woman from Pennsylvania who was working as a schoolteacher in South Carolina, instructing both slaves and freedmen, and wrote that she "came home with the blues" because she felt lonesome and pitied herself. She overcame her depression and later noted a number of songs, such as "Poor Rosy", that were popular among the slaves. Although she admitted being unable to describe the manner of singing she heard, Forten wrote that the songs "can't be sung without a full heart and a troubled spirit", conditions that have inspired countless blues songs.
