摘要

According to embodiments herein, a circular, semi-circular, or generally rounded piano keyboard is shown and described. In particular, in an illustrative embodiment, the piano keyboard is a fully to nearly-fully circular stage piano keyboard that surrounds a keyboardist, allowing for up to 360 degrees of key-play. Other, e.g., wearable, embodiments of the circular piano keyboard are also described, such as a curved keytar or a curvaceous “keydress.”
