Autistic mute discovers he can sing

You would never imagine that the song you are about to listen

in the video above, it is from someone who has never

spoken a full sentence and is still non-verbal! 
His name is Kyle Coleman who is 25 years old. 
He was diagnosed with Autism at the age of three.

This is exactly what I see on Tommy. Tommy can memorize songs. If someone who doesn't know him, hears him singing, that person would think that Tommy is verbal. Specially, when he is singing a song  and he suddenly changes the lyric. The new words  that he has introduced sometimes rhymes with the song.  My neighbor was the one who noticed it last year. He keeps doing it that even his  Aids at school have noticed it. Just last Sunday, I heard him singing:

Blue Bird, Blue Bird in the tree...

and he suddenly changed it to:

Blue bird, blue bird in the window

(while he was looking outside through the window). 

All kids like music, as well as, most kids with Down syndrome respond well to music, but they don't develop "affinity" as kids with Autism.

Here is where I see Tommy's Autism diagnosis being stronger than his Down syndrome diagnosis. Tommy has totally developed affinity with everything related to music including his voice for singing. He has a melodic voice for signging and can copy the high pitches on a song, including the ones in The Star-Spangled Banner. The way to get into his world is through music. The best way for Tommy to learn language is through songs. The best way to introduce a new concept is through songs. This is why at home and at school we sign for everything we are teaching to Tommy. Even for route counting, school uses song so 

Tommy can count at the tune of the songs. He is even learning the Pledge of Allegiance through the song of Lee Greenwood! When he was learning to recognize sight words, he could recognized them by picking the cards; howsoever, I knew he could say the words. So I began to sing the words and Tommy immediately began to read his high frequency words. We are also using visual resources to support what we teach through music, but the first choice is music. 

You may have seen this video before,
But you probably didn't pay attention on the way
 Tommy is reading. He is signing the words!
