Works

The combination of classical music, the musical atmosphere present around Texarkana (including work songs, gospel hymns, spirituals and dance music), and Joplin's natural ability have been cited as contributing to the invention of ragtime: a new style that blended African-American musical styles with European forms and melodies and first became celebrated in the 1890s.

When Joplin was learning the piano, serious musical circles condemned ragtime because of its association with the vulgar and inane songs "cranked out by the tune-smiths of Tin Pan Alley." As a composer, Joplin refined ragtime, elevating it above the low and unrefined form played by the "wandering honky-tonk pianists... playing mere dance music" of popular imagination. This new art form, the classic rag, combined Afro-American folk music's syncopation and 19th-century European romanticism, with its harmonic schemes and its march-like tempos. In the words of one critic: "Ragtime was basically...an Afro-American version of the polka, or its analog, the Sousa -style march." With this as a foundation, Joplin intended his compositions to be played exactly as he wrote them—without improvisation. Joplin wrote his rags as "classical" music in miniature form in order to raise ragtime above its "cheap bordello" origins and produced work that opera historian Elise Kirk described as "more tuneful, contrapuntal, infectious, and harmonically colorful than any others of his era."

Some speculate that Joplin's achievements were influenced by his classically trained German music teacher Julius Weiss, who may have brought a polka rhythmic sensibility from the old country to the 11-year old Joplin. As Curtis put it, "The educated German could open up the door to a world of learning and music of which young Joplin was largely unaware."

Joplin's first and most significant hit, the "Maple Leaf Rag", was described as the archetype of the classic rag and influenced subsequent rag composers for at least 12 years after its initial publication, thanks to its rhythmic patterns, melody lines, and harmony, though with the exception of Joseph Lamb and James Scott, they generally failed to enlarge upon it. Joplin used the Maple Leaf Rag as inspiration for subsequent works, such as The Cascades in 1903, Leola in 1905, Gladiolus Rag in 1907, and Sugar Cane Rag in 1908. While he used similar harmonic and melodic patterns, the later compositions were not simple copies but were distinctly new works, which used dissonance, chromatic sections and the blues third.
