The hand signals are from Zoltan Kodaly's musical hand signs taught to the   
   deaf to teach them music. When used in the movie it was something added by us   
   humans as the aliens were teaching us a language that was tonal and visual but   
   totally new to us we    
   showed that we understood by showing them that we also had visual as well as   
   tonal language
