page 2.  I have to tell you that the 30 day challenge contained a lot of pearls, such as posture, hand position, finger arch, and focus.  I've completed day 4 of the 5 day challenge and am definitely able to play at the edge of my ability.  No, I can't finger shift at 120 bpm on all the parts yet.  But I know what I'm going to challenge every day, and can maximize the value of my weekly in-person lessons with good questions.  One more day, then join the others on this week's challenge!
