A classic course, for free

There are umpteen playlists on YouTube comprising Western classical music which claim to improve concentration. I can't vouch for them but if you wish to pay attention to what you're listening and not treat it like a mere background score, then here's a course that could help. I stumbled on Yale professor Craig Wright's open course on Listening to Music on YouTube a couple of weeks ago and have been watching one 45-minute lecture every day since. Wright makes concepts like the theme, motif, rhythm and tempo easy to understand even if you have never played an instrument. And since the Symphony Orchestra of India's spring season commences next week, it's perhaps time to test your ear for music.
