Here is another thing that I do as a music teacher. I really encourage students to play a major role in their own learning. I get a lot of confusing responses from this. I will ask the student what song they would like to learn to play. Basically, I am asking the student: what do THEY want from the lessons??
What this does is it tells the student, "Hey! You are important to me!" I am also letting them know they have a voice in their own learning. Another thing that it does is it gets the student to set their own goals. I then re-enforce this idea by letting them know that I am not judging their choice. Essentially, it's their decision and I am going to support them in it. I want what they want.
This creates a win-win situation. They know i am on their side! Amazing results do come from this!!
