I never played a note I didn't mean and he was dead seiorus. As a teacher it is important to pass this kind of info along students on their musical journey. They must learn that this kind of intent' comes with knowledge and of course, time (in the form of repetitions and practice).If there were a magic potion invented for musicians, it shouldn't be for perfect performance' but for acquiring all the knowledge, confidence, and skill needed to to play with meaning at every given opportunity. Great post!
