I have been dying to find out this, what is your teacher's methods in teaching piano ?
Does he/she demo the new pieces before letting you try on it ? does she play along with you (an octave higher) to check on the accuracy of your notes ?
Once had a teacher who insisted the students getting 100% notes accuracy ( no slip, no stopping in the mid of a piece ) before she goes into dynamic ( p. ff, etc.) Does your teacher teaches the same or similiar way? :-/
