A theremin kit can be the difference between being an amazing musician at a particular instrument or giving up out of frustration. The new Theremini by Moog allows such intense tuning that it can single-handedly correct a new musician's mistakes.
The theremin itself is not a new instrument. The original theremin was patented in 1928 and since then has been helping musicians with learning and perfecting their crafts. The difference between the Theremini and the average theremin though is not only the accuracy but the ability to be as accurate as possible.
The Theremini is a theremin kit with the ability to make it so you'll never play another wrong note ever again and it does this with just a pitch control knob and hand movements. You can't replace a trained music instructor but this is pretty close.
