Maybe climbing last night made my arms and fingers TO BE RECKONED WITH. Because I just sat down at the piano and everything worked . There are these fast 6/8 rhythms I've been trying to play for months over "Such Great Heights" and some syncopated stuff over "Take Five" that I hear clearly in my head every time I play them, and I finally was able to pull off the coordination necessary to play them to some degree without it sounding shitty.
