When the ragtime era started to fade it was gradually replaced by the steady rise of early jazz (from 1915 and onwards). Early jazz bands played ragtime but also blues. A historic boost for jazz was the first jazz recordings in 1917 by the Original Dixieland Jazz Band (ODJB). ODJB had a very different instrument setting than the traditional local orchestras so contemporary arrangements by Leroy Walker for the tunes presented by ODJB gradually added a saxophone section but kept the string section.
It's understandable that the resulting arrangements do not quite catch the actual recorded sound but they are never the less interesting. Many of the tunes below became jazz standards for decades to come and none more so than The Original Dixieland One-Step. For several reasons no contemporary arrangement of this tune was published. I have therefore contributed my own arrangement, to no small part based on a transcription of the clarinet, cornet and trombone parts made by Robert Veen.
Later arrangers like Elmer Schoebel and Mel Stitzel were jazz musicians as were of course Jelly Roll Morton and they skipped the string section except 1st violin and added banjo.
