Dude, you are brilliant. My wife comes from a very musical family, but her sister has a 30-year-old heretofore undiagnosed developmental disorder, and she shows great interest in keys/strings and loves music, showing an appreciation for it, but she lacks the coordination to play these instruments.
Fortunately, she can feed herself, write her name, employ skills for self-maintenance, etc., so hopefully with that degree of dexterity, and based on your comment, a Theramin might be a great way for her to enjoy making the music that is likely in her genes and be a positive force in her life.
Thank you for mentioning this application of a Theramin! I gotta look into this after I check your link. Cheers!
