Music has been defined as "organized sound," and it's been around since the first birds sang their notes. Over the millennia, cultures have created their own versions of music because -- let's face it -- one person's music is another person's noise. Why is music such an integral part of our lives? Music lifts the heart and soothes the mind, as words cannot. We all have our favorite music styles and musicians -- from Elvis Presley to Andrea Bocelli, from The Beatles to Bach -- and music posters from barewalls.com will bring melody and memories to the walls of your home or office.
