When enthusiasm for a piano rises in the concert pianist, it is a wonderful thing. Their spirit soars, their talents fully manifest, and the listener gets emotional.

What can stir this response? Consistency note-to-note, a well-integrated tuning, and responsive repetition. They elicit confidence. And confidence taps all knowledge, feeling, and sensibility directly, without instruction from little voices in the head, without reference to who is listening or what they might think. Scales, memorization, and all forms of effort are transcended.
