African Americans played the blues as an expression of freedom and sorrow from being enslaved. The blues is an emotional music, either happy or sad-it expresses strong feelings and emotion towards something or someone, and is the musical taste of freedom. Blues is the music of the heart, soul and spirit. Blues is considered to be the roots of America's music and eventually, with much help from musical milestones such as Jazz (1910s), folk(1900s), country(1920s) and Rock'n'Roll(1940-50s), shaped and created the modern music we have nowadays.
