You are in a lounge room. Walk outside the room through the door. Take a right, go up the steps. At the top of the steps continue straight ahead, staying to the right of the large white pillars. When you reach the piano, stay to the right and go on the playing side of the piano. There is a little crevice with some storage with what looks like books and pottery. Go into the corner of that studio, to the dark poorly lit corner, where you will be staring at a mostly empty desk with a yellow light on the left side and some sort of measuring glass on the right and you're done.
