If you are in a setting where you can't do the movement, do the breath practice and imagine the movements.

These actions include things like depressing a key (NoteOn), releasing a key (NoteOff), changing a synthesizer program or patch setting and movement of a pitch wheel to alter a note's pitch.

If the quake occurs underwater, as the one in Japan did, the up-and-down movement displaces an enormous amount of water, setting off the tsunami.
