This “wee theremin”, the Gakken Theremin, is sized for a Barbie doll, but Ken Moore proves that it’s actually “playable”.

For my wife’s baby shower our friends Sarah and Mika got us a tiny Gakken Theremin so we can get our girl a head start as the next Theremin virtuosa. It’s a fun but very sensitive instrument, and since Sidney can’t even get her hand in her mouth yet I’ll wait a few more months before starting her lessons. THANKS SARAH AND MIKA!
