Etudes, can you be more specific? what do you mean by a teacher should teach you all of music, not just playing piano??I mean, you cannot say you can play piano, but you can't read music sheet paper.My teacher does teach me some basic music theory, but from now on, I am like playing sheet music, which is according to my level, and teach me new music concept from it if something is new in the piece, and I suppose to make notes of it.But nothing as I said, Ear training, and Harmony analysis.
My teacher taught me up until gr. 2 rudiments, and then I went to two other teachers for history, harmony, analysis and counterpoint. My piano lesson is supposed to be an hour a week, but usualy lasts at least an hour and a half. I usually work on around eight songs at a time (advanced rep. ARCT) we usually have time for three pieces each lesson. I just play through the piece and she gives me her opinion on expression and dynamics, keeps me on track. She taught me ear training, sight and technique as well when I was at that level.
ohhh...thanks Lagin,so, in your case, Piano lesson teaches, and ONLY teaches you how to play piano....hmmm...
