1. A piano training device, comprising:
- a keyboard comprising a plurality of illuminable keys, each illuminable key of the plurality of illuminable keys having an associated electroluminescent light source,the electroluminescent light source being oriented to transmit light toward a front surface of the key, the key being configured with a light guide comprising an elongate rigid body extending in a longitudinal direction of the key, the elongate rigid body comprising;
a light receiving surface at a rearward end of the elongate rigid body and facing rearwardly to receive light from the electroluminescent light source;
an intermediate body portion, intermediate to the rearward end and a forward end of the elongate rigid body, the intermediate body portion forming a light channel for transmission of light through the light guide;
a light redirecting portion at least a portion of which at the forward end of the elongate rigid body and below a top surface of the key, at a forward end of the key, comprising an optical guide element that redirects light from the electroluminescent light source upward; and
a light release surface facing upward;
wherein the light guide is configured to redirect light transmitted from the electroluminescent light source from under a top surface of the key through the top surface of the illuminable key by receiving light from the electroluminescent light source through the light receiving surface, passing the received light through the intermediate body portion, redirecting the received light upward such that the redirected light exits the elongate rigid body through the light release surface.
