How did classical music influence jazz music?

Jazz music is a slope of classical music without strings instruments and the beat gets faster Listen the musics of Duke Ellington like that and you'll se what i mean: Rockin' in Rhythm from the 30's: Rockin' in Rhythm from the 60's: It changes the rhythm through the years but it continues the same

Though I am no specialist I find the question interesting. I would start by watching the tools, the musical instruments that are currently used in both classic and jazz music. The most obvious I can think of is the piano. Two features in playing the piano : rhythm is given by the left hand and melody by the right hand. This holds true in both classical and jazz music. What about musical formation , You can find quartets and quintets in both classic and jazz music. There must be a lead instrument : for example flute in classic and saxophone in jazz. There has to be bass too, which holds true in bithe musical genres. There are orchestras, to play classical symphonies and standards in jazz. In terms of singing, you can find great soloists in both classical and jazz music.
