Im going to have to disagree with that somewhat...i can write my own songs but i dont know any theory...im dumb as a rock when it comes to theory...i know scales by box positions which is a horrible habit but im not sure if you consider that theory...theres plenty of musicians that dont know any theory but still play great..some may just have a good ear..im sure it would be nice to know theory but i dont have anytime
