Jazz is a music genre that originated at the beginning of the 20th century, arguably earlier, within the African-American communities of theSouthern United States. Its roots lie in the adoption by African-Americans of European harmony and form, taking on those European elements and combining them into their existing African-based music. Its African musical basis is evident in its use of blue notes, improvisation,polyrhythms, syncopation and the swung note.[1] From its early development until the present day, jazz has also incorporated elements from popular music especially, in its early days, from American popular music.[2] Rock music is a genre of popular music that originated as "rock and roll"
