One of the best ways in which sound has been used in both the scenes for getting inside the mind of the characters is the approach of voice- over. In the opening scene, Willard utters the very first line of the film in the form of voice- over, signalling the unconventional utilization of this particular device in the film. His first line is “Saigon. Shit…. Still in Saigon” (Adair, 1981). In a matter of this single line, hearing in alignment with sounds coming from outside the window (music of a marching band), Willard can be seen swearing and showing utter revulsion with respect to the war. At the same point of time, he shows that he simply wants to go back to the jungle as soon as possible. As a number of soldiers involved in any war, though there is hatred in Willard for the war, he is unmotivated and lost in its absence. This provides the audience a meaning of his life.
In this particular scene, there has been a utilization of soundtrack for the reinforcement of notion under the absurdity of war. The use of sounds has helped in the announcement of unnecessary, senseless strike of air. In this particular scene, there is huge significance underlying the concept of “Point of Audition” (Elliot, 2004). Point of Audition helps in describing what isbeing heard by the on-screen character in their world that can be related with the point of view of the on-screen character. The point of audition had been defined by Chion (1994) as two different meanings. 1.) A spatial sense: from where do I hear, from what point in the space represented on the screen or on the sound track? 2.) a subjective sense: which character at a given moment of the story, is (apparently) hearing what I hear (Chion 1994).” One mostly shows concern towards subjectivity with respect to narrative function in the scene and in the entire movie, and even in the opening scene.
In the scene of Do Long Bridge, strange reverbs and acoustics can be seen commenting upon the P.O.A of Lance as he was under the influence of LSD. At the background in this scene, low thuds of chopper seem to create an eerie perception underlying foreboding. Willard and Lance step out of the boat for finding the commanding officer at the outpost. Strange animal sounds and processed cries can be heard, depicting the increased insanity possessed by the soldiers (French, 1999). These sounds tend to be emphasizing and supporting the scene, while not diverting and confusing the attention of listener, but accentuating the sense of craze for war, along with the increased risk faced in travelling up-river. As Lance and Willard crawl across the trenches of the Bridge, they meet some crazed soldier wildly firing in the jungle.
