the pianist can also sing. Maybe some kind of narration combined with imperfect key pressed can add up to an accurate result. Maybe it isn't ideal to press buttons as it involves a lot of muscles that could send signals on their own. Typing while wearing data gloves could capture failed key presses, use them for autocorrect. if the brainwaves are also detected it seems possible to gradually get more lazy with your typing without losing anything. Maybe looking at keys on the many dedicated keyboards could be enough to trigger them at least eventually. posture could also do things. Stand while typing for all caps.
