Music teachers should let you listen to a good recording of the music they want you to learn.
An early memory of piano classes, my teacher wanted me to sight read/play Clair De Lune and for many years I never knew how beautiful a piece it could be. I could always play things much better if I heard them first, but then I imagine that would have been like cheating or something. Years later after I quit her classes (and took up other instruments, and just played piano for fun) I heard it and was like “THAT is what I was trying to play?? No wonder she thought I sucked so badly…”
