Music, Mind and Brain group at Goldsmiths, University of London. The scientific data will be analyzed to establish whether people who are untrained but passionate about music can be just as musical as people who have been formally trained. The experiment includes questionnaires and musical tests that evaluate your ability to categorize musical styles, memorize tunes, and recognize the beat in pieces of music. The tests aim to assess general musical ability.
The initiative was recently covered on BBC Radio 4's 'Today' programme.
