One TV series that I’ve watched, under duress of course, is Midsomer Murders. The theme music (you can listen to it here) is played on an instrument called the Theremin (if you’re a fan of Big Bang Theory, watch Sheldon annoy his room-mates on the theremin here). & if you’re interested in learning to play the instrument, a new Theremin mini-kit is available for purchase for a meager US$39.99 here!
