It was the stroke style of banjo that European American performers, who came to be known as blackface minstrels (see minstrel show), initially learned from African American musicians in the early 19th century. (The blackface minstrels popularized the banjo in the 1830s and 40s. Prior to that the banjo was a folk instrument exclusive to African American and African Caribbean musicians.) This was the prevalent form of playing the 5-string banjo until the advent of the guitar style of up-picking in the late 1860s, also referred to as finger-picking. The stroke style of down-picking has survived to this very day in the folk traditions of both the black and white communities of the rural South, where it is commonly referred to as frailing, clawhammer, thumping, among other terms.
