All I can say is that my daughter said she hated us and we were horrible parents for letting her quit (in the heat of the moment, but still). She’s playing catch-up right now in preparation for starting her music degree in the fall. If your daughter is going into music Ed, then skilled piano playing is absolutely essential.
We visited St. Olaf and sat in on one of Anton Armstrong’s rehearsals, and what stood out to me was that he worked with them from behind the piano. He is a really skilled player, playing parts and full accompaniments effortlessly. My daughter said she’s never heard a choir so “on pitch” at all times (believe me, she knows because she hears pitch issues that many others don’t notice). He’s known as one of the greatest choir directors, and I think his method using the piano directly (rather than relying on an accompanist) is one of the reasons. It greatly increases the efficiency because he’s not having to communicate what he wants the accompanist to do when working a piece.
