<P>... a lean, loose - jointed Negro who had commenced plucking a guitar beside me while I slept . His clothes were rags; his feet peeped out of his shoes . His face had on it some of the sadness of the ages . As he played, he pressed a knife on the strings in a manner popularized by Hawaiian guitarists who used steel bars...The effect was unforgettable . His song, too, struck me instantly...The singer repeated the line ("Going' where the Southern cross' the Dog") three times, accompanying himself on the guitar with the weirdest music I had ever heard . </P> <P> Handy had mixed feelings about this music, which he regarded as rather primitive and monotonous, but he used the "Southern cross' the Dog" line in his 1914 "Yellow Dog Rag", which he retitled "Yellow Dog Blues" after the term blues became popular . "Yellow Dog" was the nickname of the Yazoo and Mississippi Valley Railroad . </P> <P> Blues later adopted elements from the "Ethiopian (here, meaning "black") airs" of minstrel shows and Negro spirituals, including instrumental and harmonic accompaniment . 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". </P> <P> Since the 1890s, the American sheet music publishing industry had produced a great deal of ragtime music . The first published ragtime song to include a 12 - bar section was "One o' Them Things!" in 1904 . Written by James Chapman and Leroy Smith, it was published in St. Louis, Missouri, by Jos . Plachet and Son . Another early rag / blues mix was "I Got the Blues" published in 1908 by Anthony Maggio of New Orleans </P>
