Apocalypse now.

Apocalypse Now Clip
It starts off with lots of loud noise, this is good as it makes the audience believe that something is going to happen, you can hear the helicopter propellers going and the men are shouting over the noise to give it a realistic feel, then music is started this is attack of the Valkyries, it goes very well with the theme of the film, the sound of the helicopters is called diegetic sound, it is what we can see on the screen, it is what we are taking in and this is portrayed to the audience very well through this. This clip is also useful as it gives the audience an insight into what is going to happen in the scene, it shows that they are going to take flight for some reason and it most likely to go and fight.
The music which is getting played of the top is a non-diegetic sound, this is because it has been edited in after, although it has been made to give the idea that it is a diegetic sound due to the fact that you see a man turn on the radio, you here it blasting out between the helicopters, this is a very motivational piece of music and is used to show the soldiers getting into the right frame of mind for what they are about to go and do.
In the clip there are some sound bridges, this is what links the clips together, there is one clip of a man blowing a trumpet in-between the helicopters taking off and when they are in flight, this just keeps the audiences mind switched on.
There is a classic piece of music which is played over the top of the clip when they are flying above the river on the way to there destination, this could be foreseen as a happy piece and in some cases a worrying piece, this shows the different ways in which it can be portrayed, this is parallel sound.
