Of the many things we expected to see at IFA 2017, cutting-edge instruments weren't one of them. But Yamaha is using its time in Berlin to showcase the Clavinova all-electric smart pianos, which use an iOS device and LEDs above each key to teach you how to play. With the Smart Pianist application, which will also be available on Android next year, you can learn how to play tracks in real-time thanks to blue and red lights that will come on every time you're supposed to hit a key. (Red LEDs are placed above white keys, blue above the black ones.) Not only that, but if you can read music, there's a chord chart being displayed on the iPad in real-time for whatever song you're playing.
