Are you blessed with a musical brain? If you care to find out, the BBC is now running an experiment – How Musical Are You? – that assesses your overall relationship with music. It includes questionnaires and tests designed to see whether you can group together different musical styles, memorize tunes and recognize the beat in a piece of music. It all takes about 25 minutes, and, when you're done, you will receive some (desirable or undesirable) feedback. This experiment was designed by researchers at the Music, Mind and Brain Research Group, University of London, and your participation will contribute to their research into the musical brain. Note: You will need to register with the BBC to participate.
