Mozart would be rolling in his grave if he heard about the Possessed Hand.
The Japanese Possessed Hand is a recent invention that aims to make musical classes a lot easier. In fact, they might deem music classes obsolete. The Possessed Hand is comprised of a series of electrical wires which are attached to specific areas of your arm. Once switched on, the electrical currents stimulate your muscles at specific times, causing your hand to clamp up. It shapes your hand in chord positions so that you instantly know how to play instruments.
This creepy Possessed Hand definitely won't have music teachers singing in joy.
