In older people, aortic dissection often results from high blood pressure. The high pressure can cause part of the aorta's wall to deteriorate. Aging itself can cause similar deterioration.
When was jazz founded? Jazz wasn't founded; it evolved from and incorporated various sources (including Spanish military band music, Ragtime, an early form of what is now called blues, and boogie-woâ¦ogie) especially in New Orleans between 1895 and 1915.
Modal jazz developed in the late 1950s, using the mode, or musical scale, as the basis of musical structure and improvisation. Jazz-rock fusion appeared in the late 1960s and early 1970s, combining jazz improvisation with rock rhythms, electric instruments and the highly amplified stage sound of rock. In the early 1980s, a commercial form of jazz fusion called smooth jazz became successful, garnering significant radio airplay.
