Relinquishing Junk

There are numerous types of sounds occurring throughout "Trainspotting". 

The beginning of "Trainspotting" starts off with a small voice-over. This is a clear, prime example of non-diegetic sound as it is not coming from any character (or object) on the screen. Non-diegetic sound is when the source is neither visible on the screen nor has been implied to be present in the action.

Multiple other sounds are also heard from the opening of the scene. This includes the sound of the music being played on some form of radio/stereo or some other form of sound system. Next "Renton" is shown getting himself off the floor, and then shown walking out of the room. The sound of his footsteps are heard, and shown, as he walks rather heavily. This is an example of diegetic sound. Diegetic sound is when the sound source is visible on the screen or whose source is implied to be present by the action of the film: voices of characters. sounds made by objects in the scene or music coming from instruments or other devices. 

In the scene a sound of young infant or a baby is heard making noises. The fact such a young child is present in that type of atmosphere is, almost, sickening - this makes the audience feel almost sad and sympathetic for the child. This however is also an example of non-diegetic sound as the child is not visible in the shot. The sound of the young person though, is completely irrelevant in the scene. The child is never shown. These types of background noises suggest that the "Drug House" is not a pleasant place to be existing in. The different mixtures certainly creates some form of confusion towards the audience. 

Further in to "Trainspotting" a "Sound Bridge is used, "Sound Bridge's"are used when the scene begins with the carry-over sound from the previous scene before the new sound begins, allowing scene to scene to link nicely. A rather immense, loud sound of a train is heard. The volume of the train, and the fact it was a huge shock, (almost as if i was intended to make one jump). This particular sound sounded as if it was some form of warning. Perhaps it foreshadows danger, or an accident waiting to occur later on in the film. The sound however is know as "Contrapuntal sound". When we hear sound that we wouldn't associate with the events on screen, this is called "Contrapuntal Sound". For example: if we were to be watching children playing on the beach, we wouldn't hear slow, saddened music to accompany it as the two styles do not go together.

The sound of a train has absolutely no relevance, nor connection to Renton's determination to permanently stop his intake of heroin. It does, however, allow the viewers to think about what is/may be upcoming in the film and what may happen later on involving a train. Then again "relinquishing" by definition means to give up, to stop, put an end to - maybe this relates to the sudden sound of the train. Maybe an accident occurs, putting an end to something. The non-diegetic sound of the train may be symbolic.

Another sound bridge is used after the sound of the train is heard, the sound flows in to classical music. However the classical music does not fit the scene with the voice over of Renton himself. This is non-parallel to the scene.  Renton is discussing what items he has in order to help him over-come his heroin addiction. The non-diegetic dialog allows the audience to believe that he has a Mental-Health problem. I believe this because a heroin addiction is quite dangerous, and can severely compromise ones health; he seems to casual and calm about the entire situation, despite him stating that his own mother also has a drug addiction.
