This TED talk is by a well-known and wonderful music conductor, Benjamin Zander from Boston. He has been conducting the Boston Philharmonic for years now and is an excellent communicator and has given guest lectures on music and leadership. As a musician, he uses his music to teach conducting. This TED talk left me teary eyed after listening to this brilliant man. This talk was filmed in 2008 and he helps the world understand why and how classical music can be a powerful transformative tool in this world, which I totally agree. He uses a brilliant example of Chopin's music and also exudes passion in his presentation. From this talk, I took away one most important thing: the climax quote- "I will never say anything I couldn't stand as the last thing I ever say".
Do watch this and I'm sure you will agree with the transformative power of music. In fact, I work very well with classical music. Even though I like both Carnatic and western classical, I prefer and tend to choose western classical as I work for my love of cello, violin and piano.
