The exact year in which the musical style called jazz began is subject to debate, as are the origins of the word and what exactly qualifies as jazz. Certainly, the term had come to be used by 1915 for a form of music based on New OrleansRagtime music. Some of the earliest standards first appeared in 1915, and some musicians who went on to become famous in the golden age of jazz were born in that year.

Some credit the first jazz recordings to Afro-Creole pianist Jelly Roll Morton. His "Jelly Roll Blues", which he composed around 1905, was published in 1915 as the first jazz arrangement in print, introducing more musicians to the New Orleans style.
