"jig", "rag", and "coon songs". These labels were sometimes used interchangeably in the mid-1890s, 1900s, and 1910s. Ragtime was also preceded by its close relative the cakewalk. In 1895, black entertainer Ernest Hogan released the earliest ragtime composition, called "La Pas Ma La". The following year he released another composition called "All Coons Look Alike to Me", which eventually sold a million copies. Tom Fletcher, a vaudeville entertainer and the author of 100 Years of the Negro in Show Business, has stated that "Hogan was the first to put on paper the kind of rhythm that was being played by non-reading musicians." While the success of "All Coons Look Alike to Me" helped popularize the country to ragtime rhythms, its use of racial slurs created a number of derogatory imitation tunes, known as "coon songs" because of their use of racist and stereotypical images of black people. In Hogan's later years, he admitted shame and a sense of "race betrayal" from the song, while also expressing pride in helping bring ragtime to a larger audience. The emergence of mature ragtime is usually dated to 1897, the year in which several important early rags were published. Harlem Rag by Tom Turpin and Mississippi rag by William Krell were both release that year. In 1899, Scott Joplin's "Maple Leaf Rag" was published and became a great hit and demonstrated more depth and sophistication than earlier ragtime. Ragtime was one of the main influences on the early development of jazz (along with the blues). Some artists, such as Jelly Roll Morton, were present and performed both ragtime and jazz styles during the period the two styles overlapped. He also incorporated the Spanish Tinge in his performances, which gave a habanera or tango rhythm to his music. Jazz largely surpassed ragtime in mainstream popularity in the early 1920s, although ragtime compositions continue to be written up to the present, and periodic revivals of popular interest in ragtime occurred in the 1950s and the 1970s. The heyday of ragtime occurred before sound recording was widely available. Like classical music, and unlike jazz, classical ragtime had and has primarily a written tradition, being distributed in sheet music rather than through recordings or by imitation of live performances. Ragtime music was also distributed via piano rolls for player pianos. A folk ragtime tradition also existed before and during the period of classical ragtime (a designation largely created
