237: What is musical “superlearning”?

Have you been feeling stuck on something challenging in music? A section of a piece, a specific technique, an overall plateau, or maybe practice goes fine but then everything falls apart in live performance. Have you felt like you just don’t have enough time for learning your instrument and learning new music? Maybe you feel like you’re putting in the time and effort but just don’t seem to be getting much payoff in terms of results.
