Jazz fusion (also known as jazz-rock) is a musical genre that developed in the late 1960s when musicians combined aspects of jazz harmony and improvisation with styles such as funk, rock, rhythm and blues, and Latin jazz. During this time many jazz musicians began experimenting with electric instruments and amplified sound for the first time, as well as electronic effects and synthesisers. Many of the developments during the late 1960s and early 1970s have since become established elements of jazz fusion musical practice.
