The word funk initially referred (and still refers) to a strong odor. It is originally derived from Latin "fumigare" (which means "to smoke") via Old French "fungiere" and, in this sense, it was first documented in English in 1620. In 1784 "funky" meaning "musty" was first documented, which, in turn, led to a sense of "earthy" that was taken up around 1900 in early jazz slang for something "deeply or strongly felt".
In early jam sessions, musicians would encourage one another to "get down" by telling one another, "Now, put some stank on it!". At least as early as 1907, jazz songs carried titles such as Funky. The first example is an unrecorded number by Buddy Bolden, remembered as either "Funky Butt" or "Buddy Bolden's Blues" with improvised lyrics that were, according to Donald M. Marquis, either "comical and light" or "crude and downright obscene" but, in one way or another, referring to the sweaty atmosphere at dances where Bolden's band played. As late as the 1950s and early 1960s, when "funk" and "funky" were used increasingly in the context of jazz music, the terms still were considered indelicate and inappropriate for use in polite company. According to one source, New Orleans-born drummer Earl Palmer "was the first to use the word 'funky' to explain to other musicians that their music should be made more syncopated and danceable." The style later evolved into a rather hard-driving, insistent rhythm, implying a more carnal quality. This early form of the music set the pattern for later musicians. The music was identified as slow, sexy, loose, riff-oriented and danceable.
