Your music teacher isn't "responsible" for your progress. You are.
Let me explain.
Good music teachers are responsible for giving you accurate academic information and, when appropriate, stylistic suggestions.
"You", the student, have to practice as prescribed by your teacher, listen to the music that you want to be able play and use what your learn in your lessons as a springboard for further exploration.
I have often told students that I am here to "crack open the door to an extremely large room. You are free to explore any part of it but you've got to walk around."
I met a guy last year or so who complained incessantly about how bad every teacher he had had was. He was also a guy that found it hard to practice even the smallest things from week to week and one day he got upset with me when I tried to explain to him why he might not be grasping a particular concept. All I could do is throw my hands up and say "I don't think this is gonna work out ". But I was really thinking was "bro, maybe it's not them… It's you." But of course I don't think that would've gone over that well. My whole point is that the student has to be willing to be in charge learning and growth when the teacher isn't around.
