I was fortunate enough to find this marvellous video at howtopractice.com (great resource) today. Robert Duke is Professor in Music and Human Learning at the University of Texas. This video/lecture could not be more important to all educators and all learners – click here if the video is not visible (and thank you to Cornell University for distributing their resources so freely).
