Someone's signature quote said something about great composers don't borrow [musical ideas], they steal it!So, if you want to learn how to phrase and to play expressively, emulate your teacher! It will get you started.One thing to keep in mind: the only way you learn something is through immitation. If you want to memorive something, repeat it over and over. This is the same with movements, etc. Why do you remember something when you were a toddler? Because you have repeated it in your mind over and over and over (with meaning). Even if you do not purposely recall a memory, something may remind you of it and that memory is recalled. Blah blah blah.In short, ignore your own advice of not wanting to emulate your teacher. Imitation will get you started. The creative process is what will allow you to be self-sufficient.
