Ok, I'll reply one last time, pianoloverus and then I think we should agree to disagree. Because the last thing I want is hard feelings flying back and forth 🙂
At no point did I talk about skill level. It goes without saying that a skilled musician has more, well, skills and that they know a lot more about their field than a mere beginner does. As you said, that goes for anything in life, be it profession, sport, math or even general life experience.
Of course they know more about technique, more about best practices, more about anything musical. That wasn't the point I was trying to make at all, quite the opposite. Don't forget: I spent my life among musicians. Not just my parents, but as you can imagine our house was almost always filled with other professionals - both orchestra musicians and music school teachers - which made me listen to (and hear talking about) classical music a lot. I am well aware of the gruelling practicing that is needed to become (and stay) that skilled. The fact that I wasn't ever seriously interested in learning to play doesn't mean I didn't observe and learn in other ways. Even in my own music I can easily point out several ways in which I still sound terrible - and I shudder to think of all the ways I need to improve on that I'm not even aware of.
What I was trying to point out was that you sound like you are trying to say that what comes out of the mouth of professionals or advanced learners is always profound and "the way". And that is where I vehemently disagree. You may remember from those same discussions in PW that even advanced players could get in quite the p-sin' contest over those things, which means one of two things. One, (as you said recently) that both viewpoints cannot be right - which means advanced players do NOT always get it correctly. Or, two (and that is my take), that there might be more than one angle to look at something.
What I'm seeing in this thread is a great example of that - some say toh-may-toe, others say toh-mah-toe. I could nuance what I said earlier that of course my dad could (and did) read music. Of course my mother didn't have a sieve for a brain and could (and did) look away from the sheet every now and then. Things aren't all that black and white. I thought that should be obvious. I am absolutely convinced that those "non advanced" players in this thread that talked about their memorizing vs reading abilities meant their words with more nuance that you give them credit for.
Again, I actually agree with the things you said in this topic. As for your many posts, I can also say that I agree with the vast majority of them. And the posts I don't agree with, I usually still respect as food for thought. But that is not because I'm thinking of you as an advanced player or semi professional. It just means that your thoughts align with mine, mostly.
I hope I managed to say all this without ruffling feathers for anyone 🙂 And this long post got looooong. So I'll stop here and consider it a truce (and quits) 🙂
