I went to perform at Mount Elizabeth Hospital where in Orchard road.  The piano placed at the hospital emergency department lobby (level 1). I was the first person to perform, because there is emergency place and the ICU at the second floor, so all the performers should play very softly. Otherwise would make patient feel uncomfortable, and we are actually going to make some nice music to patient. So in the end, I choose to play the Beethoven Pathetique Sonata second movement.
