What do you think changed music the most in the 20th Century? My vote was for set drumming. In days before jazz, percussion was split up between many people playing a composer's score. After set drumming, people began to be the whole rhythm sections themselves, thus facilitating improvisation and personality. It paved the way for jazz, rock, etc. Set drumming changed music forever, even before electrification and more prominently than electrification. For instance, there are many, many all acoustic groups out there, but they have a set drummer. Can't do music today without set drums, unless you're an orchestra.
