I have been turning a lot of my middle school students onto Rabbath. They all really like his etudes so I am meeting with great success. As I have gone through the books I have noticed a lot of misprints. With that said, here is my question. The last etude in book 1 has a dotted 16th-32nd note bar that begins on the first semitone of the G - string (first finger to open D) and then continues the same pattern by shifting to the D - string and playing second finger to first finger on the A - string (typical tritone fingering). Why the shift? (student question, actually). I usually try not to shift unless absolutely necessary. I understand that this is an ETUDE but would I be shot dead for teaching them to not shift? I hope that this is clear enough. If not I will spell it out again.
