blues music originated as a mixture of ___ and ____
Origins of the blues Blues later adopted elements from the "Ethiopian (here, meaning "black") airs" of minstrel shows and Negro spirituals, including instrumental and harmonic accompaniment.[18] The style also was closely related to ragtime, which developed at about the same time, though the blues better preserved "the original melodic patterns of African music".[19]
Electric blues Electric blues refers to any type of blues music distinguished by the use of electric amplification for musical instruments. The guitar was the first instrument to be popularly amplified and used by early pioneers T-Bone Walker in the late 1930s and John Lee Hooker and Muddy Waters in the 1940s. Their styles developed into West Coast blues, Detroit blues, and post-World War II Chicago blues, which differed from earlier, predominantly acoustic-style blues. By the early 1950s, Little Walter was a featured soloist on blues harmonica or blues harp using a small hand-held microphone fed into a guitar amplifier. Although it took a little longer, the electric bass guitar gradually replaced the stand-up bass by the early 1960s. Electric organs and especially keyboards later became widely used in electric blues.
