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.
The 1950s saw the emergence of free jazz, which explored playing without regular meter, beat and formal structures, and in the mid-1950s, hard bop, which introduced influences from rhythm and blues, gospel music, and blues, especially in the saxophone and piano playing.
