     As a music teacher for twenty-seven years, I have always known that music touches the soul. It can break

through all kinds of barriers to reach students in a very special way. It can be the means for each child to find

their light.

     A few years ago, I was blessed with the opportunity to teach pre-school students one afternoon a week.

One of my most memorable students was Vanessa. She was five years old, had difficulty walking, and could

not speak. We mostly sat on the floor for our music lessons and Vanessa liked to sit on my lap.

     One of her favorite songs was John the Rabbit. It was a call and response song where I sang the call and

the students clapped two times while singing the repeating phrase,"Oh, yes!" Vanessa liked to put her hands

together with mine and clap with me. We performed that song during every class, Vanessa and I clapping

together. She never said or sang a word.

     One day late in the school year, when the song was finished, Vanessa turned around, looked me in the eye,

clapped her tiny hands two times and said the words "Oh, yes!" I opened my mouth and for that moment I was

the one who could not speak. Through music, we had made a connection. Several years later, I came across

Vanessa on the street in town. I stopped my car and waved to say hello. She waved back with a big smile on

her face and then clapped her hands two times, mimicking (模仿) the song we had performed in our music

class. This precious little girl, through her connection with music, left an impression on me that will last

forever. Every child has the ability to learn and grow. It is up to us educators to discover the way to reach each and every one of our students. We all must find each child's light.
