A young boy glides his fingers along the piano keys
There is no evidence that the boy glides his fingers along the keys. Instead, he may be playing deliberately or in a stacatto style. Additionally, amputees have been shown to be able to play instruments with their feet; we cannot be sure he is playing the piano with his fingers.
