Sound Behind the Door

—The sense of sound— He was curious, he opened the door, he heard a scream, then he yelped. He suddenly banged the door, someone cawed from behind the door, it changed to crackle crackle, then became an incessant echo. He again opened the door and heard, the roomful echo changed to murmuring stream, then turned into rumbling violin. He whined for annoying sound, then he whooped, then he yelled, finally he smiled and yodeled for his curiosity made him aware of many different sounds there are in the behind closed door.
