DCStudio, I usually enjoy your posts and we've had some wonderful exchanges in the past. But I have strong feelings about people, whether teachers or other, writing that they know what another person is thinking, how they are feeling, what their true motivations are, and similar. I will explain why.
First of all, it takes a long time to truly know somebody. In a teaching situation you would imagine regular lessons and thus interactions of at least a year, because a lot of impressions can be gathered. Even in this scenario there can be major misunderstandings and misinterpretations for quite a few reasons. Contrast this to reading a few words from an anonymous person you don't know at all, whom you have never met, never worked with.
My strong feelings are due to a number of experiences. I suggest that any teacher who wonders why their student does this or that, that this teacher ASK the student, and LISTEN, and that the student initiate communication as well - especially if you sense some kind of underlying concerns that the teacher is not articulating. You may well be dealing with mutual assumptions about each other. That's on the in-studio, with-own-teacher/student plane.
I will not let it all hang out in a public forum. Suffice it to say that on-line statements about what someone believes are a person's underlying thoughts can be destructive, misguided, and invasive. Not only can it be incorrect, but it can affect a person negatively quite badly. If you tell someone "Your timing is off." or "You are playing a C# when it should be D#." then the person has a concrete thing to look at. Either the timing is off, or it isn't. Either it's a D# or it isn't. But when you tell them what they are thinking, and they are induced to doubt their own thoughts and feelings, it makes a real mess. Music has a personal element to it, so it makes a mess on a number of planes. Please don't do it.
And TERAN --- since you have a teacher, trust your teacher who is working with you, especially if you are working together well. When people make statements about you on the Internet, consider that they don't know you. Do not get embroiled in explaining yourself and wanting others to get it right. The more you explain, and the more you don't get understood, the more it turns into a negative circle. I've been that route. You know who you are. Your teacher knows who you are. Your close friends and family probably know who you are.
