The Banjo, the 1800s and the Blues
There is a deep connection between the banjo and the blues, but this influence was no doubt exhibited in different ways in different parts of the country. The fiddle and the banjo were the most popular instruments in African American life from practically the earliest forced importation to the early 20th century - a span of almost 250-300 years. There's been interchange between whites and blacks on the banjo from at least the early 1700s, maybe even sooner.
