My son has completed a 100 day challenge several times with his Suzuki violin class. Like many activies, repetition and a disciplined commitment are the cornerstone of aquiring new skills. Violin is no different in this regard. As an example, I’ve included the preface from Suzuki Violin Book 3. I truly believe that Dr. Suzuki would have been fast friends with Dr. Carol Dweck (Growth Mindset researcher). At the conclusion of today’s group lesson one of the other students offered my son a new, blank 100 day challenge sheet.
