So DefinatelyNotACheese sent me a fully functional Melodica, for those who don't know what it is, it's a harmonica, but played like a piano with keys, rather than moving the mouth to different places, it's basically a piano with a blow hole! Been having a lot of fun with it, playing along to various tracks on spotify - I'm a professional trumpeter so this kind of geeky music thing was great! May have played the tetris theme tune way too many times already...

Thanks again!
