I figured I would share a sometimes forgotten point that I was working on this morning.  When working on a harder piece, don't be afraid to take a few small notes in a hard section and work on them a few at time and make it right.  Sometimes, I have caught myself trying to get through a harder section quicker to avoid dealing with the difficulty or having it's improper playing noticed less.  When I catch myself I correct it as quickly and correctly as possible.  One such instance was my chi-ru-tsu-ru in Hi Fu Mi Hachigaeshi.  I had to slow that part down and really work on it.  Now I am working on Shingetsu and I have found a few more sections in there that I am needing to iron out.  My sensei Michael Chikuzen Gould emphasizes this point and helps me work through pieces this way and his attention to detail really makes a huge difference.
