In a Small Town
Read the Text
Toscanini was a great musician. He lived in America. One day he came to a very little town. He was walking along the street when he saw a piece of paper in one of the windows. He read:
MRS.SMITH.MUSIC LESSONS.
TWO DOLLARS A LESSON.
Then Toscanini heard the music. Somebody was playing Tchaikovsky.
“Mrs. Smith is playing,” he thought, “she isn’t a very good musician. She doesn’t play Tchaikovsky well. I must show her how to play it.”
He went up to the door of the house and rang. The music stopped and soon a woman opened the door.
“Are you Mrs. Smith?” asked Toscanini. “My name is Toscanini and I want to show you how to play Tchaikovsky.”
