TheBoringPianist like how Nadia Boulanger was able to guide such disparate composers as Grażyna Bacewicz, Elliott Carter, Aaron Copland, Philip Glass, and Astor Piazzola, among others, with their own unique voices
Oh wow, that’s quite a group! And an excellent example for this discussion.
As to @ranjit ‘s original question… well and actually it gets at what @TheBoringPianist is talking about…
In foreign language pedagogy, there’s an often-discussed concept called “the zone of proximal development.” It’s so common that people just say ZPD and everyone knows what they’re referring to. Anyway, from an online summary: the ZPD refers to the "sweet spot" for learning. It is the gap between what a learner can do independently and what they can do with guidance or support.
I started learning piano over 25 years ago, sometimes people will ask me why I still take lessons. And the reason is the ZPD. I can do more, play more challenging pieces etc., with the guidance of a teacher, than I could just by playing and practicing on my own. And of course, the better teachers are always working in that zone (my current teacher is sooo good at this, figuring just what info or ideas or practice techniques will help me past a rough spot).
So for @ranjit instead of thinking about why teacher 1 disagrees with teacher 2, maybe think “what is this information/instruction doing for me in this moment, to help me get past this challenge.”
Maybe that’s a different way to look at it. Maybe not… 🙂
