A Blue Melody, a Shufflin' Beat

Blues is a vocal and instrumental form of music based on the use of blue notes—a note that is sung or played at a lower pitch than the rest of the song that gives the blues its characteristic, often sad sound. The lyrics usually have a predictable rhyme, and the music also has a repetitive pattern that typically follows a twelve-bar structure. While the blues may tackle serious subjects, it also brings joy to the singer and audience.
