That night, Oscar dreams.
Faces look up pooled and expectant. He sits with the others, the violin pinched between chin and shoulder as he's seen others do, his left hand on the strings. The music starts up and the orchestra crashes into its brief life. But is he the only one playing a role? Isn’t the audience applauding and calling out in the wrong places? And the other musicians — they’re competing, sounding their instruments randomly. The conductor points at him. He glances at his music and there is the Yellow Sign — it writhes and squirms and seems ready to reach out for him. He must assuage it. Hastily, he starts to play to its rhythm, building the sound himself note by note.
Oscar wakes up with his heart pounding. He has a vague but compelling sense that something went wrong and that he's lost his only chance to fix it. This is probably the cost of reading Der Wanderer before bed.
