I'm writing this entry with my Bamboo tablet! My hand muscles were fatigued for some reason and didn't get any better the more I played and I didn't really feel like practicing today so just did some Bochsa etudes. To change things up l tried playing Major exercises in minor as I was as playing. My technique went to sh*t as I was figuring out if I was playing in natural minor, harmonic minor, or melodic minor. Ie. no sharps, 1# on the way up and down, or 2 sharps on the way up and none  on the way down. Also, key changes threw me for a loop because the circle of 5ths really does jack for me. I have to do the "it's the key that's a minor 3rd above" thing. It sounded more interesting, at least, and kept me more mentally engaged.
