No time to write at the moment, but I wanted to put this down before I forgot.
One hour of practice today. About 20 minutes on scales, arpeggios, and inversions. More time than I'm "supposed" to spend on them, but I find them therapeutic.
About 40 minutes on the fugue. Lots of drilling on small sections. I played one small section probably 40 or 50 times. It sounded much better after all of that.
I like this drilling ad infinitum thing. Like the scales, they're therapeutic, and that's what I need right now.
