thots (I am not asking you to answer these questions. I am signaling that there are these questions.)
"I don't want you to see you nod, I want you to really understand what's going on."
In what way does she want you to demonstrate this understanding? Like, what does she want you to do? For example, teacher explains something concrete. Student shows, "Like this?" Student indicates what s/he doesn't understand, instead of politely nodding. Student takes it home, works with it, and next lesson says "I worked with it, but I don't understand this part."
/ You will never get anywhere with this sloppy fast practice like this even if you practice 100 times/ do not think that you can just slack off, do not find any excuse for yourself..."
How to practise is a big bugaboo that we often see with teachers; i.e. they don't teach how to practise. "Please teach me how to practise." - and then see if this teacher knows how to teach it.
I came away from my first lessons, which were on violin, with the inkling that there was a "how" that I was just starting to get as far as I had figured it out. The piano teacher I work with stresses the "how" greatly. He teaches it to all students, even those who have had music lessons before, because too often this is missing. In his case, this includes
- "chunking" music into smaller sections, to be practised separately
- "layering in" different elements in those sections during the week, such as getting the notes and fingering; adding things like dynamics when the first is solid
- working in shorter periods of maximum concentration (focus on particular things), maybe several times a day, rather than one long session
- more things
Obviously how you play in front of her might not even reflect how you practised. For example, if a teacher makes me feel uncomfortable constantly, I might end up rushing (or in my case: freezing up and going blank)
Her "feedback" is imprecise and thus sloppy. It's not really "teaching", is it?
she never starts on time for her lessons because she'd always go overtime with her last student(she was 40 mins late one time). and she Never apologized for being late.
That part shows poor attitude, and is not professional.
