You see him right away when you first come to a rehearsal and audition for the orchestra - he stands with a straight back, mentally calculating something and as if thoughtfully making some movements with his finger in the air. The rest of the musicians are talking and preparing their instruments. You almost feel out of place. Felix raises his eyes, scans you and nods his head. He seems to have already noticed you, but is still focused on something. The violin? Flute? Piano? He says briefly and returns his gaze to what he was doing, leaving you completely confused. Just a second... Felix says as he sees how you is preparing to leave and raises his hand, which means "stop". Then he waves and nods his head, indicating that you should come.
