For various reasons, I'm teaching DD myself at the moment as we are between piano teachers. This isn't great practice, but I'm sucking it up for the next few months.
When the new syllabus is released in June, I will get her to choose 3 pieces she'd like to learn.
Do you normally start with one piece, and add others as the student gets more confident, or start learning them all roughly the same time?
She'll be working towards Grade 2 if that's any help - so very early on in the journey!
