If you are using a computer, hold down the shift key and press a number or letter to play the black keys.  If you are using a device like a mobile or tablet, you can press the black keys directly on screen. The following illustration shows how Virtual Piano keys are logically mapped to a computer's keyboard.   ADDITIONAL TIPS: TIP 1: The Virtual Piano's black keys are layed out in the same order as on a physical piano. So you will notice the keyboard keys (black keys) are also in groups of 2 and 3 with some keys in between skipped like on a physical piano. TIP 2: The black keys are also known as flats or sharp keys. TIP 3: Each number and letter on your computer's keyboard corresponds to a white piano key.  Use Key Assist on the main piano to see the two different key maps.
