This is a story I heard about ten years ago.
My sister’s friend, Sara, decided to join the choir at their church. Her first night at rehearsal, she picked up the music and took her place in the soprano section.
Sara had sung in choirs before and she could read music pretty well, but she noticed right away that the soprano part was very high and she was having trouble reaching the notes. Also, she thought she might sound screechy because the woman sitting next to her kept looking at her strangely.
At the end of the page, the director stopped to ask if the sopranos were having problems. Sara told him perhaps she should sing alto because the soprano part was so high.
That’s when she discovered she was singing the notes written for the hand bell choir.
