I must disagree with the advice previously given, especially about doing things behind your teacher's back.
Let me guess your ethnicity: you are Chinese or some other rice-staple derivative.Your teacher is Caucasian.Asians and Caucasians have different communication styles. He's probably older so don't expect him to learn how to improve his communication skills because he may not be aware he needs it. But you do.Asians tend to have some weird thing about regarding teachers with respect and stand to be distant from them because they are viewed with reverence. This is a mistake in Western cultures. Westerners like the status but they don't like the behavior Asians use for reverence which is to speak little and do everything they say. Instead, they like to be complimented for their knowledge and abilities and use chit chat to communicate.Here is how you'll improve your communication skills. Ask him about how he started playing the piano. If he said his mother made him, tell him your mother made your play, too! (But only if it's true.) Try to get him to talk about difficulties he's had in the past and what he did to improve his abilities. If you can make a transfer from his response to how you would like to improve your own abilities, and be challenged, make it known.During the conversation you can prime him by using these terms: excel, strength, speed, dexterity, facility, technique. Priming is the insertion of an idea that relates to a larger piece. Notice that these priming words relate to the playing aspect of piano. What will happen if you use these words in conversation is you steer it toward this topic. This is where you can build up an idea in your teacher's mind and then when the opportunity arises, you transfer these ideas onto yourself, and how he can help you improve them.Communicate!
I've just started with a new teacher for less than 2 terms. my teacher is good but how do I get him to push me more?
