The conductor appears in relatively few of the ninety-nine exercises, "Comedy" (Part 5), "Casual" (Part 7), "Biased" (Part 7), "Reactionary" (Part 9 ) and "Opera English" (Part 10 ) being most notable. Throughout his various appearances, however, the character of the conductor is portrayed consistently. He is essentially surly, officious, and self-important, making him an intriguing parallel, in some ways, to the similarly self important Young Man. This also makes him a source of tension; very few people are comfortable being confronted with mirror images of themselves.
