Ever been listening to a sad song wondering why it sounds so darn sad? Happy, sad, peaceful or angry — there's just something about music that makes us feel a certain way. Apart from any lyrics, there seems to be much more to music than meets the ear. In our investigation of how and why we perceive music the way we do, we talk to physicist Dr. Roy Briere and music theorist Dr. Richard Randall from Carnegie Mellon University, and psychologists Dr. Meagan Curtis from Purchase College and Dr. Shantala Hegde from the National Institute of Mental Health and Neuro Sciences.
