Answer: A. Jacques-Louis David and John Singleton Copley
Explanation:
Jacques-Louis David was a French painter who made his name with the Neoclassicism style. He was considered one of the best of his era and by being so contributed greatly to the popularity of the Neoclassicism style.
John Singleton Copley was another prominent Neoclassical painter. He was an American by birth but Irish by descent. His paintings were said to be innovative compared to other paintings of the time because his style related to everyday life.
Directors do what they do best, direct people. They send students to their places and begin to start the play. They tell students their lines and explain what they will do, what movements, what accent, guiding the student, directing them.
Orchestra conductors do the same. Most people think that conductors just move their baton to the sound of the song. Incorrect. A baton is moved in a pattern that goes 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4 so that conductors can always direct and tell the performers what beat they're on. So if they get lost they can read their music, see what beat they come into and wait for the conductor to wave the beat.
