When my daughter was five, we gave her a piano as her birthday gift, with great excitement; she began learning piano under the teacher’s guidance. However, when she was no longer curious about it, she became sick of it. After all, it is a tough job to learn piano, not to mention the daily routine of practice. Therefore, every time, I had to urge her again and again, either to force or offer her some profits for the practice. She always felt uncomfortable sitting on that stool, so she would either scratch her nose or ears, or hide in the bathroom for quite a long while.

Her first teacher left and moved somewhere else; my friend introduced me to an American teacher. The American teacher’s way of teaching was complete American style. After practicing, she would give my daughter some good comments on the excellent part (despite it being just a small one), and then point out what should be improved. What’s more, every time she came, instead of beginning the lesson right away, she would first play some music. She said, “To learn playing the piano, you should learn not only the skills of playing, but more importantly, to feel the music and love it.”

To my surprise, my daughter gradually became fond of piano lessons. Sometimes she even would like to show off a little bit in class after her skill had reached a certain level. Her confidence and sense of achievement were enhanced with the appreciation and acknowledgement from her teachers and classmates.

Surprisingly, my daughter said to me one day, “Mom, I was lucky because you didn’t give up my piano lessons.Learining piano is like climbing a mountain. You’ll feel tired when you are on the way. When you look down from where you are, you will realize that you have been making progress. But if you stop, you will never take one more step.” Hearing these inspiring words, I could not hold back my tears, thinking: that is the very thing I want to teach her, something that is more important than learning piano.
