The Air Piano is a portable musical instrument that encompasses the functionality of a grand piano. When folded, the Air Piano is small enough to fit in a pocket. When unfolded, it extends to 5 feet. The body consists of lasers and sensors running along a frame that has been segmented for folding. Wiring throughout the body connects the sensors to the speakers on the outside of the frame. The Air Piano also has Bluetooth capabilities to connect to external speakers. Sound is emitted when the path from laser to sensor is interrupted.
