I've been "playing" my piano off and on for fifty years. I would go through periods of intense practice trying to push myself to the next level. I could recognize some patterns in the music I was trying to play, but I was basically just sight reading, and I was not getting better. In frustration I'd stop playing until the urge to get better would hit me and I'd start the cycle over again.
Christina's music theory class has been a game changer. Music is starting to make sense to me. There is a very definite structure to how music is written and the more I learn about that structure, the more my playing improves. My fingers are starting to naturally move to the correct places (or at least to places that still sound good even if I'm not playing the song exactly as written). I am enjoying my time at the keyboard more than I ever had, and I'm playing more than I ever have.
So if you really want to start to understand music and to enjoy playing it, I can't recommend this course enough. You won't regret it.
