Nora the cat was just a normal house cat. The owner is a piano teacher, and soon Nora started mimicking the owner's students playing the piano and the owner herself. The owner decided to put Nora on Youtube, and she was an instant success. Later down the road, an expert who was a music composer using computer technology saw the video on Youtube and decided to have an orchestra play around the notes Nora was playing on the piano. Pretty cool....lol
