No sound. I can't hear the music without hearing aids. I can't understand the words with hearing aids. All I can do is sing what I can understand from the lyric. Someday I will get the help I need to be able to sing the lyrics that I created and didn't created and have sound added to them. If you wonder how this song goes without any sound, just focus on signs and body language and you will find your rhythm along with what emotions will rise inside you. If you don't understand any of what is being shown in the video, I suggest you to take classes on ASL ;) ASL is nothing but gem.
