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.”
Mrs. Smith was very glad to meet the great musician. She asked him to come in. Toscanini played Tchaikovsky for her and went away.
