Thanks to “The McClintock Piano Course”, for the first time in my life, I became conscious of the ultimate value of being correctly taught how to play intervals from the very beginning….. Programming correct intervals with your fingers from the score without visual control of the “distance” between the keys is, however, not only a basis for a good piano technique…. Being an Otolaryngologist performing micro-surgery in ears and especially on the vocal cords of singers and professional speakers, I know that the “distant” touch of what you want to “take out,” or “make an incision” is basically determined by what your eyes (and cortex) want to be done. And during micro-surgery, you cannot control what your hands are doing — only the results at the end of your instrument counts….. I am sure that the way your Course has taught me to play the piano will be of great advantage in micro-surgery. But your method is not restricted only to surgery, I feel that it can be of great help to professionals of all kinds.
