You are also like a river, an ocean breeze, a shaggy willow-tree dancing in the wind. So yeah, the chemistry gets a bit fuzzy, & muddy, and your instruments and meters go into the red and on the fritz. Yikes. You miss connections. You drop things. You struggle thru the motions of the day. Weird. One day totally clicking, and in-tune, the next day is all dissonance, false notes, broken strings. Searching for the right combination of elements. Day to day. It's a grand experiment.
