This piano was created by separating the keys out of an electric keyboard from the controls, to make the controls face upright on an old piano. If you have the urge to ruin a perfectly good piano and an electric keyboard, then you may be interested in this doing this yourself. But if you find another use for 250 hours of your time, kudos to you. As for the music in the video, no comment.
