Should we mention at the bottom that a copy is being sent to the prosecutor? What do you think? This piano teacher has just gone completely crazy this year. She shakes the younger child's head to make their brain work, crumples sheet music, throws around hands, presses on fingers until they hurt, pushes against their back, and screams nervously over a single mistake. She behaved similarly in front of me (pressing with pain in her back, correcting every finger painfully throughout the lesson, while the daughter stayed silent and endured it, sweating profusely, but who knows... with what force she presses?). In general, she screams at other children too, hitting them on their elbows if they droop. Meanwhile, she whispered to the daughter the entire lesson and was on the verge of a breakdown, which was obvious. She didn't let the child proceed to the exam... saying, 'shameful to play like that'... although they've been to a tutor... and out of 4 pages of pieces, the daughter makes a mistake in only one, in a single line (memorized incorrectly, we're re-teaching now), and in the other, a small measure hasn't been practiced either, so they can't play the Scherzo directly at a mega-fast tempo. In general, nothing critical. But the teacher said... 'shameful'... Bach gives you a 3... so we won't be presenting this in November at the concert. In other words, she's not letting the child proceed with the submission. I'm about to write a complaint about the rude treatment of the child directly to the director.
