So, one day all day I'm getting all my notes right, slotting them almost instantly up and down the scale, all is progress, and I'm in my happy space. It feels good. I've got C major, D major, and E major all working up and down - the only three scales I know thus far. Next day, nothing is working right, I'm struggling to do what I did almost effortlessly the day before and I feel like tearing my own face off in frustration. Anyone else have this type of experience?
