When Jack emerges with the choir, he is described as a commanding figure with an air of authority. The choir follows him in an organized manner, displaying discipline and military precision. This scene sets the tone for Jack's leadership style and establishes his dominance over the boys.
Jack immediately creates the impression of being someone who is completely in charge of his choir. They obey his orders immediately and you get the impression that this may be at least partially from fear of his temper. Jack's order for them to remain standing in the hot sunshine is unnecessarily cruel, so he is boy who enjoys wielding power but not always wisely. His manner when talking to Ralph and the other boys is arrogant, he thinks he is the best thing on Earth and he expects everyone else to recognise it too. Jack is bossy, insulting to Piggy and dismissive of any people who he considers of little value, which is pretty much everyone except perhaps Ralph, who's power and popularity he envies and coverts.
he volunteers his choir to be the hunters
Jack and his choir were at the top of the mountain when Ralph spotted the smoke from the ship. They were supposed to be tending the fire, which they let go out while they were hunting.
Yes.
Hunters
Jack is the only choir boy
When Jack and his choir first marched down the beach they stopped close to the platform and Jack, alone, vaulted onto the platform to speak to Ralph. When Ralph explained that they were having a meeting and said, "Come and join in." The choir began to scatter from close line. Jack shouted, "Choir! Stand still!" The choir obeyed.
When Ralph is initially elected leader he confirms that the choir still belongs to Jack. Jack says that he wants his choir to be hunters, to supply the boys with meat by hunting pigs. After they light a signal fire on the mountain Jack says that his hunters will take on the responsibility for keeping the fire lit.
Jack has taken on the responsibility of leading and conducting the choir during their performances and practices. He is also responsible for organizing rehearsals, selecting music pieces, and ensuring that the choir members are prepared and on schedule.
Jack and the choir boys.
The choir wear shorts and shirts, a box shaped black hat with a silver badge (Jack's badge is gold as he is the choir leader). They also wear a long black cloak, which has a silver cross on the breast and a ruff around the neck.
Jack hunts with the choir boys and makes them into his hunters.
