The blues music became popular in America during the early 1900's. Guitar, piano and harmonica were the basic blues instruments. Blues style had started with mainly the instrumental type of music but later singing also played a key role in most blues songs. This music was mainly originated by the African-American community in the southern United States. The origin of the style is also closely related to the religious music of the African-American community. The original blues songs were played by slaves and poorer white people mainly conveying sorrow and defiance. Later the style developed into various forms such as country and played a great role in development of rock and roll.
