As a music teacher,I have always known that music touches the soul.It can 3 6  aII kinds of barriers to reach students in a very special way.It can be the  37  for each child to find their light.1 would like to  38  a story about it.

For a few years I was  39 with the opportunity to teach disabled students.One of my most 40 students was a five-year-old girl called Vanessa,who had difficuIty walking,and could not speak.We  41  sat on the floor for our music lessons and Vanessa liked to 42 on my lap(膝上).One of her favorite songs was“John the Rabbit.”It was a clapping and response song where I sang the call and the students  43  twice while singing the repeating phrase,“Oh,yes”Vanessa liked to  44 her hands together with mine and clap with me.We probably performed that song during every class,Vanessa and I clapping together.But she 45  said or sang a word.

One day,when the song was finished,Vanessa turned around,46  me in the eye,clapped her tiny hands twice and said the words“Oh,yes!” I opened my mouth in 47  and for that moment 1 was the one who could not speak.When my heart 4 8  started beating again I looked over at the assistant teacher to find her also 49  through music we had  made an awesome connection.

Several years later,I met Vanessa on the street in town.She waved with a big  50 on her face and then clapped her hands twice,imitating the song we had 5 1 so many times in our music class.The little girl,52 her connection with music,left an impression on me that will last forever.Every child has the  53 to learn and grow.It is up to us to 54  the way to reach each and every one of our students.We all must find each child’s  55 .
