  • Why this patent rocks: This patent appears to relate to the Brock360 Circular Keyboard. The list of inventors includes Lady Gaga’s lead keyboardist Brockett Parsons. Consisting of 288 custom machined keys (24 octaves), the Brock 360 comprises four 72-note keyboard sections. The user stands in the middle and the keyboard surrounds them. If you’d like to see the Brock360 in action, see here for a video of Parsons playing it. If you would like to know more about PianoArc’s circular piano, see here for a link to their website.
