Close Encounters of the Third Kind
Steven Spielberg · 1977
The UFOs sound a five-tone musical phrase. When scientists broadcast it to space, the reply is a series of numbers that turns out to be coordinates for Devils Tower. At the end, the scientists answer the aliens with their own notes. Music is how the two sides first talk.
Where to see it: The Devils Tower finale. Lacombe answers the aliens' five-note phrase with hand signs, and the alien answers back before the ship leaves.
