Close Encounters of the Third Kind

I decided to research Close Encounters of the Third Kind because of it's obvious sci-fi genre relating to the scene I am editing but also because it is composed by John Williams, one of the greatest composers, I believe. 

The five tone musical structure used in this film to communicate with the aliens is so incredibly iconic; Williams has the ability to create a memorable tonal tune, for example, his two tone motif for Jaws is recognisable all over the world and is purely only two notes played over and over again that immediately sends a sense of fear into the room when it is played. 

The motif for Close Encounters is a five tone progression which universally translatable, is supposed to musically resemble H-E-L-L-O. The scene where the aliens and the humans communicate through sound, the five notes is really striking as you see, unlike other alien films, that both species are happily communication with each other without a problem. This kind of alien sound, I can't really take inspiration from as the aliens in War of the Worlds are hostile and are trying to kill the humans than communicate with them.

The sound from the ship itself as it comes over the mountain, starts as a low rumbling sound and then gets louder as the majesty of the mothership comes into view. As it gets closer to the landing strip, a close up of the ship sounds a low humming sound to match the pulsating lights but the general sound of the ship is a low rumbling that changes in pitch to show a sense of space. I like the idea of having a low humming sound to show the inner workings of alien machinery as there is a part in the War of the Worlds scene where there is a close up of the light pulsating on the alien probe that I could take inspiration from.
