It could be very easily argued (because it's true) that the music addressed by this lecture was the inevitable result of the evolutionary trajectory of all of Western music . Nevertheless the compositions of Arnold Schoenberg represent a hugely compelling intellectual/artistic achievement that could only have come from true visionary genius . Learning to hear and appreciate the free atonality 1908-1923 and 12 tone music of Schoenberg can and will allow you to hear all of music with fresh phonological ears . This is music beyond the precipice the Tao the Ching where Yang becomes Yin and Yin becomes Yang . It is nothing to fear it can re-illuminate and re-inform your musical world . It is where all of music history was heading . My god don't you want to know? This lecture ends with "The Berg Violin Concerto" ; five posts it took to get to the end . So on my channel there are 4 more posts continuing this lecture .
