Immovable as a mountain

Here's a good way to keep your practice laser-focused and avoid accidental mistakes:

Take some deep breaths, relax your body part by part but at the same time imagine that your organ is positioned on the platform between the two skyscrapers each around 500 meters tall.

​The key here is your eyes.

If you can penetrate with your gaze the score or the keyboard (when playing without the score), then you'll become immovable as a mountain.

No inattentive audience, no sharps or flats, no pedal passages, or left hand trills can touch you.
