Bill Keith ( William Bradford Keith, December 20, 1939 – October 23, 2015) was a five-string banjoist who made a significant contribution to the stylistic development of the instrument. In the 1960s he introduced a variation on the popular "Scruggs style" of banjo playing (an integral element of bluegrass music) which would soon become known as melodic style, or "Keith style." Keith was born in Boston, Massachusetts. He attended Amherst College and graduated in 1961.
