 | | In addition, it could be argued that jazz would not exist without both instruments invented or developed by Europeans (the trumpet, saxophone, trombone, double bass, etc.) and the previous work of Europeans in music theory, which was explored in different ways by jazz musicians, such as increased use of the seventh chord and extended chords. |
 | | Early jazz influences found their first mainstream expression in the marching band and dance band music of the day, which was the standard form of popular concert music at the turn of century. |
 | | Jazz has roots in the combination of Western and African music traditions, including spirituals, blues and ragtime, stemming ultimately from West Africa, western Sahel, and New England's religious hymns and hillbilly music, as well as in European military band music. |
