Okay, so I've been taking from one piano teacher for pretty much all my life (1st-9th grade), and I've really enjoyed it. However, lately, her health has been failing, and it's starting to look like I'm going to need to find another teacher pretty soon.
I know any teacher I find is probably going to be much harder than my old one, who was really laid-back. All she had me do was scales, chords, and then whatever music I was assigned (and maybe some ear training or theory here or there).
So... since there's some really great pianists here, what would YOU try to look for in a teacher? Is technique important? Should I be doing arpeggios, cadences, etc.? One teacher I've talked to noted that my "technique" needs work; how do I go about improving that? Also, do I need to find a super-hardcore teacher who's going to demand I practice like a madman, or can a somewhat-rational teacher be just as good (since I probably am not majoring in music in college)? What about piano competitions? I've never been in one; would they be helpful?
