Im very far away from being able to control the nuances of volume. Im still at the point, where I'm learning to use my left and right hands independently and play without looking.
And that's what SimplyPiano gets you to - it's a structured program+game that teaches you to read music and gain hand independence using an app.
Im pretty self aware that I will need a teacher at some point. I have been a gamer and had formal teaching in music when I was kid.
I find it hard to believe that a teacher would be able to correct me in real time, while simultaneously having me enjoy the process. Once I start playing half decently, the memory of music is motivation enough.
Not right now.
