The purpose of a lesson is to check on progress and introduce new material based on that progress. The purpose of the lesson is not to practice or be entertained. A private lesson is not a band class. It should be considered a privilage to study with any teacher. Immediate gratification is not to be expected when it comes to music.
Music begins once technical problems have been solved.
Highest respect is mutual and expected. The student should make a genuine effort to devote time to practice. Look for solutions not excuses. The answers you seek can usually be found in the practice room. The only bad question is the one that is never asked.
