Being on the lookout for the new in the moment, whatever the moment, is quite the opposite attitude from what I expected a music teacher's life to be. The best teachers I ever had mystified me at the time I was studying with them -- in my late teens and early twenty's.
Fenner Douglass, himself a young organ teacher at the time, listened with an open mind, never dictated, always reacted as if equal to equal. I didn't appreciate it sufficiently at the time. Perhaps I expected him to be more authoritarian.
Hans Neumann, a much older European piano teacher, made quite clear that he was himself interested in what I brought to my lessons -- in fact, I realized at one point that he assigned me problematic works out of curiosity as to what I would make of them. But I was enough older by that time, a veteran of battles with other teachers .
