Computerized tutor in 'smart piano' helps realize a childhood dream

At the age of 27, Zhao Yutian achieved his childhood dream - to play the piano. He could not read the score, but with the help of his iPad and the lights on his keyboard, his fingers danced to Chopin's Nocturne.

Zhao's family could not afford a piano when he was a boy. But now, although "with no more worries about food and clothes", the Internet entrepreneur no longer has the time to learn to play the piano from the very beginning either. But now, he has the smart piano and he can learn to play a tune within a few days, if not hours.
