Music was diverse during this time. People listened to classical and opera; jazz and blues; folk music and pop music. Australian musicians and singers also made it into world stages. Popular music was often connected with social protest movement and civil rights and campaigns. Peace, freedom, choice and difference were strong themes. Ballet was popularized in Australia but both ballet and opera continued to appeal to small minorities of the population. America had an enormous influence on Australian music, and American musicians tended to consistently top the 'pop' charts in Australia. A lot of people were listening to American music.
