Thanks for the suggestions. I do not really mind to let him to do whatever he wants. I am only wondering how his teacher can instract him beauce teaching tradition is very classical oriented and I feel that his teacher apart from changing the repertoire, has no idea what to do with him, she is experementing. The patern here is Bach, Czerny, scales apr. and a a piece. If you do not fit to this, teachers loose reason for existance and they do not know how to motivate the student. I see for example that he is very interesting imporovising with electronic insturments. For example he plays parts of the Mozart sonata facile by changing rithim and adding different sounds and he can go forever by doing this.
